EggfinderTx --> Mapsphere, In-flight Position and Altitude Peformance?

It's actually easier with the B6 board... just connect the output of the uBlox to the left pin of the RUN jumper (leave off the jumper...), and you can pull GND and 3.3V from the LCD interface header. There's nothing special about the LCD's expected format... it just wants to see standard NMEA data, which any GPS should be putting out.

Chris, Kurt,
Thanks for the good information.

Here's a couple of photos of two hacked EggFinders. The signal out from the GPS module is soldered to the second pad closest to the board edge. The circularly polarized Ublox Chipset I have both in and out wires soldered but it
isn't necessary.



Sorry, my camera isn't that good. Kurt

For those of you that want to convert TRS Eggfinder NMEA logs, please find attached excel spread sheet.
It reads in the file EggFinder.nmea
You then need to set the Launch altitude and the Landing Timer - this is to be set to the NMEA Line number that occurs first after landing. It is used to suppress the Apogee reporting that occurs after the TRS lands.
There is the ability to extract to a NMEA or GPX

Note that the extract process validates the NMEA checksum resulting in a smaller but cleaner log.
