Adding GPS to the V2 cubesatsim displays its Lat Lon and Elevation

[W7DGP]

Earlier this year I was reviewing cubesat sim info provided by AMSAT and found that a GPS module can be added to the V2 cubesat. Info from Alan Johnston, KU2Y recommended some modules and how to wire one to the cubesat. My module of choice is HiLetgo GY-NEO6MV2 NEO-6M GPS Flight Controller Module 3V-5V with Super Strong Ceramic Antenna for Arduino EEPROM APM 2.5 I bought at Amazon for $8.99. The module is wired to J12 on the Main Board. Only 3 wires are needed: Vcc Gnd and module Tx to J12 RX2. I used very flexible wire so I could later tuck the module and antenna into available spaces. Overall the only difficulty was disassembly of the cubesat to reveal J12 with room for a soldering iron, wires and fingers. J12 is on the Main Board (the one in the middle of the stack). After completion and some close inspection, I decided to see how it works. I set the sat up outside in a Styrofoam box to keep it out of the rain (I live in the Seattle area) and pulled the flag. I used config -p (show payload) to display the data. Within a few payloads, GPS data was showing added to the end of the payload data: "GPS 47.7464 -122.1938 86.60" As shown, the cubesatsim already has the GPS software running so the NMEA sentences get translated and posted to the payload data. I believe the last number, 86.60 is elevation because I'm 90 meters above sea level. I also changed the mode to APRS (config -a) and brought up Direwolf on my Fox In A Box and the GPS data shows being transmitted in an APRS packet.
