| Overview The Global Positioning System (GPS) is a satellite based navigation system operated and maintained b> ilio U.S. Department of Defense. The GPS consists of a consigliali on of 24 satellites providing worldwide. 24 hour, iliRv dimensionai i.i-D) coverage. Although originally conceived Itir military needs. GPS has a broad array of civilian applications inclinimi; surveying, timing, marine, land, aviation, and vehicle nav igation. Ci PS is the most accurate technology available tor vehicle navigation. My compagne llic disiai ice lo li PS satellites orli i line the earth, a (iPS rccei\ er can calculate an acculale posit inn. Ii TS receivers can also provide precise UTC lime, speed, and course measurements which arc beneficial for vehicle navigation.

Based on AC li II (il'S'™ core of Trimble Navigation Lid. . the receiver features a RS232 serial communication port and a RS232 level pulse-per-second (PPS| output for liming applications or as a general purpose s\nchroni/aiion signal. Two independent serial channels can be selected on llic serial pori: selection is accomplished through an internal jumper or a digital input. The GTS800Ü operale- ti-ine cither of three protocols I limbic Standard Interface Protocol (1 SIP™ '), Trimble ASCII Interface Protocol (TAIP™ '), and NMEA 0183. The module also suppons RTCM SC-104 for DGPS (differential GPS). User sellings, including pori para mei ers and rccen er processine options, are stored in a non-volatile electrically erasable ROM (I I:K< IVI ) that does not require, backup power.
