I have bought a sunken PH1 around a year ago, managed to get it fly, but it is not able to see the GPS signal properly.

I have hooked up the board to my saleae and I have wrapped this tool to read the Saleae logic analyzer output CSV:

It turned out that it see some satellites, but the link quality is very poor: CNO (Carrier to Noise ratio) was mostly 0 and sometimes 28-30.

So I have replaced the ublox receiver module (to an uBlox 6T), it see more satellites, with better CNo (27-33) but still no signal lock in the system.

I have ordered today a ANT1575-2540A from the TME and we will see.
There is a ALM-1912-BLKG in the antenna path, but I have not been able to source it yet. And my hopes to the antenna is pretty high :D.

Schematic diagrams for the Tyco Mutator RC car (gathered from the FCC site).

Back in the days when I was kid I would give a lot for these docs when my car broke down. (It is waiting since then for the BL conversion...)
