GPS CONCEPTGPS CONCEPT

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

CONCLUSIONCONCLUSION

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.
