Arrows on STIR +

[ExoticRadar]

Have any of you noticed the little arrows that light up on + ?
I noticed it last week when i marked a spot on the +. And when i drove away, little arrows appeared on the far left of the display showing me where i was relation to the marked spot via gps. The arrows display at 0,45,90,180,270 degrees. It would be so easy now to have escort/bel now just make a lil program. So we can have the arrows like the v1....
I would pay for that software upgrade.

Lets use this thread to cast your vote. If u would pay a reasonable fee for arrows to be on the STIR + like the Valentine arrows. Say "yes" or forever hold your peace
If there is a groundswell of "yes" votes i will forward to the right person at Escort/Bel

The Plus knows where to point the arrow because it knows GPS coordinates of the marked location relative to your current location. Unless it can pin point the radar location just from the signal (which I doubt), the Plus doesn't know your relative location to the radar. The only way it would be able to do that if it had additional receiver(s)/antenna(s) to determine the direction of the signal (by analyzing which sensor/antenna receives the strongest signal).

X2... the V1 has 2 antennas, which allows it to determine the direction the signal is coming from. The STi-R+ has only 1 antenna. It would be a neat upgrade though, add a 2nd receiver module to mount on the back of the car, plug it into the CPU, and have instant arrows for radar & laser.

I know the v1 has 2 antennas (Large Front horn. Small rear horn). Im just not sure if 2 antennas is required to get a "right" red arrow alert from a 45 degree of axis radar source.
Does a small rear v1 horn antenna thats facing towards the rear at 180. Even pick up a 35 or 40 degree radar source miles ahead? Seems a bit of a stretch to me. But ill be the first to say i dont know how v1 does it.

Even V1 can't accurately calculate the exact location of the source. It's all in the signal analysis and algorithm used to "guess" where the source is. My guess is that most of the time, when V1 alerts, both antennas are actually picking up the signal (due to signal reflection). Then the input from both of them is analyzed, and based on the "strength" of the signal from each antenna, the V1 makes an educated guess on the general direction of the source. And if both antennas are picking up the signal of the same strength, then the source must be beside you. I'm sure it's more complex than that, but you get the idea...

I would think they Escort would need to add a rear antenna to get arrows. This would make the STi R Plus much better. Arrows are very Important.

That raises a question. If you have a v1 out in the desert where there is literally no objects to get radar reflection. How then is the V1 rear horn able to pick up anything? It cant...I have seen videos of v1 working in this environment. I understand what your saying...

In order to get a 180 degree alert sure...youll need a rear antenna. But to get an alert at 45 or even 90 degree. 1 horn is able to do that. The issue resides can the LNA in a + distinguish between a 0, 90 270 degree radar source. I dont know...Ive looked at the LNA in the + and the part # doesnt reference. But the x band LNA does. So i might be able to get the schematics and see if its able to do that.

Of course the + with radar locating arrows would be awesome. My v1 came through with another "from behind" locating shot today. The + alerted first, but the v1 let me know where it was coming from.

The same algorithm would still apply. If it were shot from the front, only front antenna would be able to pick up the signal, so the software would "guess" the front direction. Likewise for the shot from the rear. If it were to be shot from a perfect 90 degree angle, then I guess it would come down to the ability of each antenna to pick up an off-axis shot like this. If both antennas were able to do it, then you would get an accurate guestimate of the direction (side arrows). If only one of the antennas was able to pick up the signal (let's say the front one), than you would probably only see the front arrow light up. And if neither was able to pick it up, then obviously the V1 wouldn't alert at all.

To my understanding and from what I've read, the V1's rear antenna has an extremely wide "field of view" versus the front antenna with a much narrower "field of view".
