1 Open sky, all SV RF signal level = -130dBm, Number of GPS SVs > 6, Number of Glonass SVs>5, Number of Galileo
SVs>5, Number of BeiDou SVs>5
2 TTFF values show results in worst conditions (as an external host user): timing measurement start when GPS control
request is sent on AT command interface and stop when NMEA frames (1Hz update) display 2D fix information.
3 Scenarios used for accuracy measurements simulate car travel including direction, altitude and speed variations.
4 The performance are obtained by using external Pre-SAW and LNA for conducted test setup at Room temperature, it is
used to simulate the active antenna
as customer’s application.
5 1Hz Navigation used for all tracking/navigation tests.
6 GNSS constellations used: GPS + G G Beidou
7 Accuracy data are provided Circular Error Probable, CEP-50 / CEP-95. Means that 50%/95% of the positions returned
calculated have an error lower or equal to the accuracy value.
8 Tracking sensitivity is the lowest GNSS signal level for which the device can still detect an in-view satellite 50% of the
time when in sequential tracking mode..
9 Acquisition sensitivity is the lowest GNSS signal level for which the device can still detect an in-view satellite 50% of the
time.
Note:
All GNSS characterization data are measured in conducted RF path with GNSS simulator at room
temperature.
