ALP and GPS

[angrypenguin]

My understanding of the tx head is that it requires the ALP CPU to be connected to the GPS antenna, and that's for IP protection.

My guess is that it's harder to reverse engineer the thing if a requirement is that the sensor has to be moving at a particular speed or higher. Anyways, (since I don't care to reverse engineer duck all), my question is more from a usability perspective.

Let's say I'm speeding in a tunnel, and there's a cop who dings me. Since the GPS receiver can't connect to a satellite...

1) I guess I'm screwed because for all intents and purposes the ALP thinks I'm not moving? Am I right, wrong here?
2) Is there a way for me to know if/when the system is actively ready and alert?

Right now (I don't have the GPS unit), when the ALP system is ready/active then it goes blue. I assume that at a speed below 30km/hr (since I'm in Canada), it doesn't go blue, and once I go pass the minimum speed it then does go blue to alert me it's ready?

Am I off base here? Thanks

You will be ok in the tunnel provided you get hit over the 18Mph thresh-hold, you may here GPS lost but you are still ok and Im sure the light will stay blue and you will be protected, Tom has told us over and over to not worry about tunnels and we are good to go!!

Thanks - I also now have to figure out where the blip to put the gps receiver. Is it alright if I put it behind a plastic front grill or is the sensitivity relatively poor such that I have to put it in the cabin where there's a direct view of the sun?

EDIT based on initial readings it seems like the receiver is waterproof...

[System]

No problems with tx. There's a 500m tunnel here and defense mode will stay active through its entirety

People have put the GPS under their dash and have had no issues--seems like you can put anyplace you like and be good to go

Thanks. I think for appearances sake I'll put it under the plastic cover that's under the windshield wipers on the passenger side. Therefore it's only one plastic cover between the GPS sensor and the sky. I know the cable is stupid long so I'll run it through the firewall and into the engine bay, and then feed it all the way to the other side and hide it underneath the plastic cover.

Gosh I have too much time on my hands this weekend :p

[System]

Yeah I have mine under my steering wheel with my CPU. No issues there!

[V1Jockey]

I have mine at the base of the windshield below the wipers and it works fine.

On mine with legal tint you cannot see the puck form outside in shade or sun.

I put black electrical tape patch over the LED (it reflects off the glass too) and tried a custom thin patch and found the puck is semi transparent and the light glowed to the sides of it.
So I put a normal width patch and had to curl it over the edge because the LED wrap's the corner.

Being my interior is dark it looks OE back there. And I want to point out the LED is not super imposing bright. It can only be seen at night and with any kind of outside ambient light or glare from lights behind me it can't be seen.

Makes no sense to have GPS, why force a product that does not need GPS to use GPS?

It's also our right to protect users who don't realize they can damage their eyes from sitting there and having IR shot in their face. TX Sensors will not fire if the vehicle is not in motion and GPS is required for anyone wanting to use them.

No reason needed. Just because should be sufficient. ALP customer service is outstanding, and even the CPU upgrade policy is great for those that still had the HW1 CPU!

Really, no body is being forced to do anything.
I speculate we may never know all there is about the GPS integration.
All I know is how many times ALP has saved me large dollars in fines, fees, community service, probation, and insurance rate increases.
If ALP said I needed to add a bobble headed Chihuahua dash ornament in the rear window it would be there. Heh!

Really?

Lets not talk about rights. Much better ways to communicate than that.

Ok, so after searching and asking others it appears the GPS actives jamming if you have TX sensor above 18 mph. If you do not have TX, the threshold is user selectable?

From what others have said ~18mph is the threshold to begin jamming which is certainly acceptable. I was worried it was 25 or higher.

You didnt know that? that has been discussed and hashed around 1000 times lol

[winterbrew]

Yes, 12 to 56 mph (20 to 90 km/h) in 8 user selectable increments.

I've been running mine with GPS and regular sensors for a few years, set to 40 km/h which is the lowest speed limit (school zone) here.

[tphank1]

I have the regular sensors and GPS (got it for the NR) and set the threshold to 12 originally. Still on the fence about getting the TX until I do some more testing with 3 std to be bulletproof against the DECs

just for clarification, if wanting to use a TX sensor, you need the GPS antenna. The GPS antenna plugs into the alp main box? and no other module is needed?
