Dudu7 GPS signal

Arnaud

The accuracy here is exceptional and shows the best reception possible. Even though there are only a few satellites. Usually 5-10 meters accuracy on the DUDU7 at best...
Phone was inside the middle of the car, usually +- 1 or 2 meters on the phone for hours at a time...

I will have to remove everything and reposition the antenna, but I followed the forum recommendations.
Which location is best on your car?

Since the adhesive sticker is on the bottom, there are not many places.

Thank you.

Every vehicle is different, so you'll need to find the optimal position yourself. Also, note that your dashboard isn't level—it appears to be tilted inward.

I will try to relocate the antenna. What is the max amount of satellites that can be expected in view in Taiwan?

Even though I can see 100 with my phone?

This is different. Your phone can detect more satellites but with lower accuracy. The DUDU7's positioning chip is the UC6580, which boasts strong signal reception and high precision.
Even in extremely harsh conditions where phones fail to locate, the DUDU7 can still pinpoint your position.

Arnaud I agree with @DUDU-Meng, the gps on DUDU7 is one of the best I've seen. I've got it connected to OEM external GPS antenna and takes 3 seconds literally from cold start to obtain a fix with 3m accuracy. After some time goes down to 1m.
My phone on snapdragon 8 gen 2, takes probably same amount of time, but even if it's triple frequency, not dual, and seeing 3x more satellites, does not go below 3m of accuracy.
So far, all of the gps problems people have in this forum is the antenna or antenna connection. Also bear in mind some cars have anti heat metallic layer in the windscreen effectively blocking almost all signals.

Good feedback, I will check.
My phone inside the car consistently gets much better reception. I will check my install and move the antenna and report here.

Is their possibly a recommendation for maybe a exterior antenna. Or can we get some specs on the antenna and what the Dudu7 supports for frequencies so we can maybe locate a external antenna?

Arnaud

I fixed my GPS issue by relocating the cable only. I now get about 50 satellites consistently. 😊
Thank you all for your patience and support.
Happy Holiday!

Arnaud What do you mean you are relocating the cable only???What did you do???

Arnaud

My wifi, GPS, power to DVR2K and USB cables were tapped together behind the glove box. By running and coiling the GPS cable by itself ( it is about 1.5m too long), I was able to get most of the expected satellites in a few seconds. I only tested a few times today, but this was 100% better than my precious experiences.

It seems that your previous issue was caused by interference from the entanglement of feeders and other cables.
Congratulations on resolving this issue
