• 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 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.
NOTE: Skipping each digit of easting and northing coordinates decreases the accuracy by the
factor of 10.

GPS Accuracy
The GPS Location Service accuracy depends on the GPS coverage and the selected accuracy mode.
In good GPS 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.
• 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:
