● ●

24 SATELLITES IN 6 ORBITS, 6-9 ARE IN VIEW OF THE GPS RECEIVER AT ANY TIME REQUIRES A MINIMUM OF 3 SATELLITES FOR LOCATION AND 4 FOR ELEVATION UTILIZES PRECISE TIMING FROM SATELLITE TO RECEIVER TO DETERMINE LOCATION AND ELEVATION REQUIRES LINE OF SIGHT TO SATELLITE RCVR COMSEC ALLOWS MAXIMUM ACCURACY

PLGR Cold Start or Standby ●

Cold Start: – If PLGR has not been used for a month or more or if the Almanac is old – Present position greater than one degree from last known position

●

Standby: – PLGR has been used within a few days AND present position within one degree of last known position 9

CONCLUSION The PLGR is a great tool for navigation, but it takes training to ensure continued proficiency in the use of the device and still requires each soldier to understand military map and land navigation techniques. 53
