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.
The LMR Master Technical Data Sheet provides a list of options and the
Note
measurements that require GPS (Option 31).
