Okay, there are a few factual inaccuracies here. First, GPS is not designed to give a view of more satellites to US territory than the rest of the world. The orbital planes are equally spaced around the Earth. GPS.gov: Space Segment

Second, the term "GPS" can sometimes be used to refer to any device capable of receiving satellite navigation signals. Many chips actually receive, GPS, GLONASS, and Galileo signals, all in one device.

However, you are correct that GPS is not as reliable in the high latitudes. The orbital inclination of the satellites is only 55°. Galileo is only 56° inclination, and GLONASS, as you might imagine, has a higher inclination, at 64.8°, because the Russians have a lot of arctic territory and care about coverage there more than other countries.


Yep, that analysis is spot on. There are no benefits. In the best case, it's useless. In the worst case, it's going to get someone a ticket.
You can disagree as much as you like and quote as many sites as you want. I see my satellite count on my Trimble GPS screen from early morning till evening day in, day out. My system is worth more than most peoples vehicles. I have surveyed in South Africa, Australia & Canada - You might know a lot more about radar/laser but my knowledge and first hand experience of GPS I'm sure outweighs most! Satellite numbers during the middle of the day are far higher than those at night - do you think this is coincidence? If the planes were equally spaced don't you think you'd have the same amount of satellites roughly at all times of the day.... I challenge you to look at this on even a less high tech device. Do you even know what the difference is between the L1, L2C & L5 Signals without Googling? Back in the day when there was fewer satellites there were "windows of time" where GPS worked and others where they didn't - sound equally spaced? Don't believe everything you read online. I have first hand knowledge of this and merely trying to share being someone in the know.

I'm well aware of the different "GPS", My work device is capable of receiving: GPS, GLONASS, Galileo, Beidou (CHINA) and also QZSS (JAPAN) - I need not be lectured, I had a professor for that. I trust that was for anyone that didn't know! I have had up to 33 Fixed Satellites at a time with the total in view being 41 (Less than 10 degree mask gets dropped). How do you think I can survey at accuracies of less than 20mm in trees. As I said I stand corrected but the ALP Device only uses GPS - The American One and likely at best L2C signals - these are cheap units, we buy them for C$85. Probably only worth C$25 at most. Does that sound like a highly capable chip to you?

I would guess that this has something to do with transmitted signal strength rather than number of satellites actually visible from your location. On the daytime side of the Earth, the satellites are getting sunlight on their solar panels, which isn't true on the nighttime side. But unless the orbits are eccentric (and GPS satellites are not eccentric, because they have a well defined and constant height at all times), there cannot be a significant variation between number of visible satellites on each side of the Earth (daytime vs nighttime). Since circular orbits all have the same orbital period and trace roughly the same paths relative to each other at all times. You're trying to suggest that the orbits are setup so that more of them always are visible from the daytime side of the Earth and we know that these orbits are the same height above the ground at all times, which is actually physically impossible. The only such "orbit" that exists is at the L1 Lagrangian point between the Earth and the Sun. And of course an object at that point won't stay exactly at that point without continuous stationkeeping because there's more to the Solar System than just the Earth and the Sun. I guess you could put a bunch of satellites near the L1 Lagrangian point and let them "orbit" that point, which would make them all visible only on the daytime side of the Earth, but that's not the way any satnav constellation operates.

LOL, I think the delay problem also has to do with AL using a crappy chip that can't sample fast enough when a vehicle accelerates. What a joke.

High 5 for someone knowledgeable on GPS here. In the Army we used to have Rockwell DAGRs that were absolutely terrible - at that point I figured I'd need to learn everything I could if I wanted to survive and the way geolocation works is literally three-dimensional math. I'm sure quick fix technology has come a long way since then but it seems like you know what you are talking about.

I can agree with you all that to us it's an unnecessary step, but for now we are stuck with it and can acknowledge that ALP should weigh consumer input.

Devils advocate, if GPS is so easy to get past, why not just do it in your car?

In the same breath, we KNOW about this and if you KNOW that your particular setup lags, why not be more cautious when you expect it to drop out and also try to both improve your odds for less lag and communicate your issues directly with ALP directly? Sure BRD is here, but information coming from one angle only does so much.

You mean, put a GPS signal generator and Faraday cage in the car and then place the GPS receiver into it? That's definitely possible, but of course the problem here (other than the fact that GPS signal generators are bulky) is that now we have yet another component that can fail and leave you unprotected.

Just FYI: The first time I brought this issue up on this forum (not in a public section though), as far as I can tell, was in August of 2017. I've been complaining about this literally for years and nothing has changed. It got to the point where when my car was totaled and I needed new ALP heads to replace the ones that I did not remove from my old car, I simply opted to not buy a Tx head.

I do wish I could agree with you on the daytime / nightime but the satellites move so quick I really don't think it is an issue.

GPS satellites (the American ones at least) zigzag across the horizontal plane of the Earth up to certain latitudes but not higher. Places closer to the equator thus have more of a chance of receiving more satellites as the distance to both extremes is less than from one extreme to the other - it also helps the Elevation mask (Inclination as you mentioned) dramatically. This could have been done on a vertical plane but what good does a GPS signal do over the Arctic or Antarctic.

Satellites do 100% have the ability to remain relatively (it doesn't matter if it moves slightly) geostationary. Corrections would just be sent from various ground stations much like they do on moving satellites. This is how TV broadcast satellites work. The ground corrections from specific base stations (makes my system look like childrens toys) sent up are what make GPS work, as they say in the event of a Zombie Apocalypse don't rest your hope on GPS, it's probably gone on the 1st day!

Is it possible maybe to use some sort of software to log the communication with the antenna and build some piece of hardware to loop that data back to the ALP cpu?

This sounds like it's an opportunity for some testing out of tunnels....
Personally I think the Going to the Sun Road in Montana would be a great place!!! Tunnels and Mountains!

The GPS will just be transmitting lat/long/alt in some standardized format. The computer is parsing this data to get speed. You'd have to spoof the readings (either by fooling the GPS as mentioned or sending it false readings that always have you moving at X speed). Again, still a failure point.

Fwiw, I'm researching systems to add to my car, and this flaw is making me seriously consider TMG over ALP at this point.

Yes, but there's a huge difference between geostationary and something that's only visible from the daytime side. An object in a circular low earth orbit orbits the Earth approximately every 90 minutes. As the orbits get further and further from Earth, their orbital period gets longer and longer. A geostationary orbit is simply an orbit that:
1) Has an inclination of 0 degrees (is above the Equator) AND
2) Has an orbital period equal to one sidereal day, or around 23 hours and 56 minutes (one day is actually 24 hours long but the motion of the Earth around the Sun contributes the additional 4 minutes or so to each day). This is the amount of time the Earth takes to make one revolution in inertial space. Thus, it says above the same point on the ground at all times.

This happens at an altitude of exactly 35,786 km and at no other height. Further out, objects take longer to orbit the Earth than one sidereal day and, when viewed from the ground, they tend to move "backwards" compared to objects closer than geostationary height.

When you're talking about satellites only being visible from the daytime side, they're actually not orbiting Earth at all in the traditional sense. As in, they're not circling it but rather they're hovering at a fixed position relative to both Earth and the Sun (independent of which way the Earth or the Sun are rotated at any given moment), which only happens at and around the L1 Lagrangian point.

I wouldn't think a module which connects to the same port that repeats a constant loop of output data would be no less reliable than the antenna itself....

You're taking me back to University days. I don't dispute your facts. My point still remains this is set up for America first especially during daylight hours. GPS satellites are not all positioned equal, although all in relatively close altitude to each other the small differences are intentional and make a profound difference. The maximum latitudes they extend to also differ slightly - again making profound differences. This is not by chance but very carefully calculated for America's benefit, the rest of are just glad GPS is not a Geostationary system which it could easily have been set up as.

I'm sure you're familiar with the term RAIM prediction then. On older aircraft equipment, RAIM is harder to acquire at night, just as you stated. US Military requires a valid RAIM predict before dropping any sort of laser guided ordinance. If you're going to thread the needle with a Paveway near allied troops on the ground, you NEED valid RAIM predict in order to "be legal".

To keep things on topic, I think the ALPs GPS is cheap, as per one of my previous posts.

I forgot to mention multi pathing as another very possible cause for delay. Basically GPS signals reflecting off mostly nearby human made objects, high rises etc but natural objects too such as if you have tall trees either side of the road . This can cause even the the best of equipment to temporarily get confused - sometimes a full dump of all satellites is required on my work equipment. In places of tall foliage or mountainous regions it is not uncommon to acquire a better fix when the Elevation mask is changed from 10/13.5 degrees to +20 - It does seems counter intuitive as one would be receiving less GPS signals but the quality overall of said signals improves as the poor signals have been removed from the equation - more doesn't necessarily mean better. More, oftentimes means more processing power required and that comes at a cost naturally. Also poor signals require more processing. I can tinker my settings but you can't do that on the ALP.

With this GPS delay in focus I have been trying to see how quickly my led changes to active upon coming out of the Underground parking daily. I'm often up to 500m away from the entrance/exit and well over 30kmh by the time this changes....

I can't say I've ever looked at an ALP Stats file but I still like the idea of a GPS attached, not as a requirement for the TX obviously but having a location and speed at time of jamming is pretty neat.

I personally still run a Garmin in my vehicle, not because I need it for navigation (I mostly Waze) but as it is constantly logging location and speed and stored in a easily accessible file - wouldnt that be nice on the ALP. Never know when you might need that data. Garmins also still work in places of no cell signal - (a very real Canadian problem especially up north). The speed is also true (mostly) as opposed to the vehicles speedometer. Speedometer is also analog and Garmin Digital. I couldn't justify the HUD cost but still debating a aftermarket one. Dashcam strictly has no GPS for obvious reasons!

Just noticed the delay myself after thinking about this post.

I was in traffic, behind other vehicles and the LED for my ALP’s didn’t change from yellow to blue till I was at 45 km/h ( 24.2 mph).

I really didn’t put my foot into it as I was in traffic

I watched tonight in my car, not sure if it has to do with geographical areas or what... But mine turns before my speedometer in my car, my R7 and my phone all hit 20mph. Clockwork. Every time.....

Not minimizing your experience, but sharing mine. Makes me wonder if some aren't having antenna issues.

The thing is, even if it works fine for
50% of people MOST of the time, it only has to fail for you one single time, at the wrong time and boom. Ticket.
Based on a couple observations you’ve made on your own system are you now 100% convinced you’re rock solid in all situations and it’ll always engage on time? You’d bet your wallet, even license on it?

To say nothing of the tons of us where it seldom goes into defence mode right at 30.

A simple software update to remove (or at least adjust) the ineffective attempt at protecting IP and suddenly NONE of us need to worry.

It’s really a no-brainer on their part. If AL wants, we can write a google article on how for $2 everyone can defeat their GPS “protection” at will to study the system operation. But I’ve specifically avoided detailing that, even here, because I’m still hoping they will do the right thing in good faith.

On the contrary, even if it was a $10k piece of equipment it is still a piece of electronic equipment. Electronics are fallable. A head can fail any moment going down the road, a rock can crack a lens, a bump in the road can allow a PT etc. Let's be real here - the only way to safeguard your wallet and license is to maintain < / = PSL.

This is the same way my system has functioned from day one. I agree it's a silly thing to us, but for ALP, an engineer designed it that way for a purpose and as stated before people have been complaining since the TX head rolled out - it doesn't mean it will change just because we think it's dumb or that it should.

I count on my system to be reliable within it's limits - I know if I stop or slow down, accelerate a certain way (in my case this makes zero difference), hit a tunnel etc. I have to make sure it goes into defense mode again by utilizing the status LED which afaik is included in all kits. It's also well documented in regards to how GPS works with TX heads and is a setting option to notify you if GPS drops. I understand people are concerned about PTs during potential fluctuations in GPS, but that's ONLY if you're running a TX head. If you are, at this point you should know the limits of your system. I also agree it's a silly programmed feature, but I also think it's slightly negated by the fact if you are worried about potential tickets in a zone at < 20mph or even a little more a driver should be more cognizant of what their system/car/and they are doing on the road. This may be a complete different tangent, but one I believe is relevant.

Sure it should be reduced or removed just the same, but on some level we have to take responsibility for ourselves first and the documented limits of our equipment. This thread should be titled 'My lack of attention is going to get me a ticket when the gps on my ALP system lags and I don't see it activate/deactivate.' Your status LED tells you what's going on, it isn't an odd unknown if you are or aren't protected.

Let's take our requests to the manufacturer, rather than bicker amongst ourselves about the few people this really impacts, on a forum not even monitored by a representative of that company.

My comments were purely in regards to my experience with my system and I confirmed that I saw what I always see tonight. Your mere assumption that just because I take the time to confirm before commenting that I dont understand how my system works 100% of the time is short sighted. There are very few people here complaining that there's an issue here. Obviously there's a market for ALP and if this was a problem for even 30% of users wouldn't you think the manufacturer would take steps to combat it? Think about it this way, ALP is already a niche product, and TX head users are only a small subset of that niche market....

Again - no excuses for them, merely pointing out we have a responsibility to ourselves first, and then to voice our concerns not only amongst ourselves - but to the support folks who matter.

Here's the tough question....

Who here has reached out to Radikal LTD?

Also, again - who's to say there isn't an equipment issue with certain antennas that's causing intermittent problems.
-- Double Post Merged: --
Sorry, long rant... I'm not disagreeing with any of you.... But we're all adults here who many installed our own stuff. I'd wager over half of all ALP (or even TMG installs haven't even been tested properly against (minimally) guns from around one's home area.

This is completely ignoring that every single gun is different with potentially different firmware revisions and levels/qualities of calibration.

My comments were purely in regards to my experience with my system and I confirmed that I saw what I always see tonight. Your mere assumption that just because I take the time to confirm before commenting that I dont understand how my system works 100% of the time is short sighted. There are very few people here complaining that there's an issue here. Obviously there's a market for ALP and if this was a problem for even 30% of users wouldn't you think the manufacturer would take steps to combat it? Think about it this way, ALP is already a niche product, and TX head users are only a small subset of that niche market....

Again - no excuses for them, merely pointing out we have a responsibility to ourselves first, and then to voice our concerns not only amongst ourselves - but to the support folks who matter.

Here's the tough question....

Who here has reached out to Radikal LTD?

The company has been contacted directly by members from this area with inside access to AL Croatia, with these same observations and concerns, recently (since this thread). So it’s not like this post is the main attempt to get these issues to the relevant parties. However, making threads like this is still important as it not only shows manufacturers the problem is more widespread than a couple users, but it also lets those who may not be ALP users yet know about big design limitations. That may factor into their buying decision for TX heads (as it has for some that have already posted).

It probably is a small number of customers that this issue affects, relative to the total number of systems in use worldwide. However, I’d argue it is many of their most important customers that this is affecting. If you don’t know already (you probably do), this area (Edmonton, Alberta) is far more heavily enforced (with LIDAR and everything else) than anywhere else in North America. There are more ALP systems in use here than probably any single other city, most users just aren’t on the forums. They found about about AL in the first place through local groups and word of mouth from those of us that were more into the equipment. I’ve installed over a dozen systems, just myself for people over the last couple years. And talked with close to a hundred more about it in that same time frame. Many other active members from here have probably recommended ALP to as many, and installed the same number of systems in that time. There is massive interest in jammer tech because of the absolutely huge threats we face here.

Also, many of the new guns and FW updates are all encountered here first, and much of the testing is conducted here for LIDAR. There is a lot more to consider for AL than just the number of users when it comes to addressing the concerns of what could be perceived to be a small group. A niche market? Maybe. Their most important customers? Absolutely.

I’m not sure why (or even if) there is any ‘bickering’ here though. There is not one good argument to support retaining the GPS limit. So how could anyone possibly argue anything? It’s either ‘it doesn’t affect me, but I support fixing it’ or ‘it does affect me, and I support fixing it.’
I guess there are people that believe the earth is flat, but I’m talking about intelligent people.

Obviously, if I know something isn’t working right (or is failing by design, as is the case here) I’ll work around it. Until just recently, it wasn’t shown to be an issue which could land me a ticket however. Everyone assumed 30km/h was low enough, and that it always armed on time. We now know that’s not the case, and can take steps to deal with that until it’s sorted out.

But just because I can ride my bike safely when it has a flat tire, or choose to walk it instead, doesn’t mean that’s really a great option. Or that I should have to live with it.

Finally, if I assumed that you didn’t know what you were talking about, or how your system works, it’s not personal at all. I deal with every single person I encounter as if they are a total idiot until I’m proven wrong. As it is my experience so far in the world that more often than not, that’s the case.
