•
Time - indicates when the last time the location was calculated. The time is provided in Universal
Time Coordinated.
•
Letter Code - grid zone or square on the map for different coordinate standard
•
Latitude - expressed in degrees, minutes, and seconds.
•
Longitude - expressed in degrees, minutes, and seconds.
•
Number of satellites - used to calculate the location. In general, more satellites make for 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.
