Building an extremely small ARPS Tracker

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

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!
