Before this, I think we would need a Really Rugged Tracker.

Something that can be attached to the outside of a backback and be
operated in all possible rain and temperature conditions.
Integrated SIRF III GPS, OT1+ tracker engine, proper sturdy
connectors for external power and RS-port for bidirectional NMEA
feed for external GPS. Frequency-agile TX/RX radio, I'd say minimum
2W out. Internal battery that must be able to be field-replaced without
special tools maintaining IP67 protection must be capable of 8 hours
of SAR operations field use in all temperature conditions.

Yes, it sounds not cheap. But proper APRS depolyment in SAR enviroment
requires this.

If we could integrate Bluetooth, it could be quite easy to connect to a general-
purpose terminal like Nokia N810. It is not IP67, but could be stowed in the
pocket.

Any rugged GPS units with open source platform inside, so that APRS messaging/
agile waypoint capabilities could be enhanced?
