Number of satellites – used to calculate the location. In general, more satellites provides better
accuracy. The maximum is 12 satellites.
• Easting – refers to the eastward-measured distance expressed in meters.
• Northing – refers to the northward-measured distance expressed in meters.
NOTICE: Skipping each digit of easting and northing coordinates decreases the accuracy by
the factor of 10.

GNSS Accuracy
The GNSS Location Service accuracy depends on the GNSS coverage and the selected accuracy
mode.
In good GNSS coverage (at least -137 dBm or in open sky), the location accuracy presents as follows:
•
In high accuracy mode, the accuracy is:
- 5 m for 50% of location reports.
- 10 m for 95% of location reports.
• In power optimized or normal mode, the accuracy is:
- 20 m for 50% of location reports.
- 50 m for 95% of location reports.
NOTICE:
The presented values depend on variety of factors, for example the view on the sky. To
optimize the GNSS performance the radio should have the clearest possible view of the open
sky.
