1 Project goal
This project has the goal to assemble a lowest possibly imaginable power saving and absolute supercompact highly packed APRS traching transmitter.
2 Ingredients
At last, I got all my ingredients collected:
- EM-406A, a 20 Channel SiRF III GPS Receiver from USGlobalSat with Antenna
- Open Tracker SMT
- Radiometrix HX1-144.800-3 300 mW transmitter
3 Data
3.1 Datasheets
- http://www.sparkfun.com/datasheets/GPS/EM-406A_User_Manual.PDF EM-406A User Manual
- http://www.datasheetarchive.com/pdf-datasheets/Datasheets-3/DSA-56110.pdf RadioMetrix Module Datasheet
- http://www.sparkfun.com/datasheets/GPS/NMEA%20Reference%20Manual1.pdf NMEA Reference
3.2 Other data
4 Project plan
- Find a cabling arrangement that works
- Program the Opentracker SMT
- Rearrange all the three components on minimal space
- Build a suitable case
5 Tests
- Since I have my APRS relay station ready to go anyway, I just need the tracker to start tracking!
