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.
