Emergency Periodic
Profile (LRRP only)
Radio is in emergency operation and given time interval after the last location report expires.
The GPS icon is displayed in the status area when GPS has a location fix. Optionally, your service provider may
configure the radio to always display the GPS icon, even outside of GPS coverage or before the radio has acquired a
location fix, i.e. right after being powered on. In this configuration, the GPS icon blinks until a location fix is
acquired.
This is a selling feature.
GPS Military Grid Reference System
The Military Grid Reference System (MGRS) is the geocoordinate standard used by the military for locating points
on Earth. The MGRS attempts to represent the entire surface of Earth on a worldwide grid. The grid is based on the
UTM (Universe Transverse Mercator) between 80°S and 84°N latitudes and UPS (Universal Polar Stereographic)
systems.
The UTM area is divided into 60 longitudinal strips, each 6° wide. The strips are numbered 1-60 beginning at the
180°-174° W (Zone 1) and increase to the East. Each strip (or Zone) is then divided (horizontally) into 8° latitude
bands.
