Tracking 16 dBHz.
Hot Start 23 dBHz
Warm Start 28 dBHz
Cold Start 32 dBHz
The sensitivity value is specified at the correlator. On a GPS Evaluation
Receiver using SiRFXTrac2 firmware with the supplied antenna, 32 dBHz is
equivalent to -142 dBm or -172 dBW. Other board and antenna
equivalent to -142 dBm or -172 dBW. Other board and antenna
characteristics will vary.
