     Operational Limits

     Altitude < 18,000m (60,000ft) Velocity < 515m/s (1,000knots)

     Time To First Fix (TTFF) a) Cold Start 60sec (typical) In a 'Cold Start' scenario, the receiver has no knowledge of position, time or the satellite constellation. The receiver starts to search for signals blindly. Cold start time is the longest startup for this module b) Warm Start 40sec (typical) In a 'Warm Start' scenario, due to a backup battery the receiver knows its last poison, the approximate time and the constellation almanac. Thanks to this it can quickly acquire satellites and gat a position fix faster then in 'Cold Start' mode. c) Hot Start < 3sec (typical)

     In a 'Hot Start' scenario, the receiver has been powered off for less then 2 hours since the last valid navigation solution. The GPS uses its last Ephemeris data to calculate a position fix. Re-acquisition time 3sec typical (within 60sec GPS signal obstruction)
