N900 Hardware GPS
This is a page outlining the capabilities and what is known of the GPS.
It may be a Navilink GPS, from TI. The Navilink series is detailed here.
The GPS is not connected to the main CPU, but to the processor in the phone module, hence cannot be directly communicated with. [1]
User reports of lock times
With software GPSjinni (from extras-devel), and clock set to reasonable accuracy.
- Lock time after 12h or more of no GPS, with no cell, and no wifi active.
- Indoors >10 min - 2 signals strong, but no lock - no time fix reported.
- After getting lock outside, powering down, and then inside, lock in 2 mins.
- Outdoors - no lock with gpsjinni after 5 min, lock after 1-2 with location applet. Perhaps an invalid result.
- Indoors >10 min - 2 signals strong, but no lock - no time fix reported.
- Lock time after 12h or more of no GPS, with no cell, and wifi active.
- Lock time after 12h or more of no GPS with cell active, but no data connection.
