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.
