Chapter 9 — GPS (Option 31)
9-1 Introduction
The LMR Master is available with a built-in GPS receiver feature (Option 31) that can
provide latitude, longitude, altitude, and UTC timing information. This option also enhances
the frequency reference oscillator accuracy in the Spectrum Analyzer mode. Within three
minutes of satellite acquisition, the reference oscillator will have an accuracy of better than
50 ppb (parts per billion).
In order to acquire data from the GPS satellites, you must have line-of-sight to the satellites,
or the antenna must be placed outside without any obstructions. An Anritsu GPS antenna is
required.
9-2 Activating the GPS Feature
Install the Anritsu GPS antenna onto the GPS Antenna connector on the LMR Master.
1. Press the Shift key, then the System (8) key.
2. Press the GPS submenu key.
3. Press the GPS On/Off submenu key to toggle the GPS feature on or off. When GPS is
first turned on, a RED GPS icon appears at the top of the display.
Note
The LMR Master Technical Data Sheet provides a list of options and the
measurements that require GPS (Option 31).
