Function
USER SEGMENT OF SATELLITE-BASED POSITION LOCATING SYSTEM. ANTENNA PICKED UP SATELLITE SIGNALS & SENT THEM TO RECEIVER-SIGNAL PROCESSOR WHERE DOPPLER SHIFT OF MOVING SATELLITE WAS MEASURED. PAPER TAPE PUNCH PLACED DATA ON TAPE. PAPER TAPE READER INPUT DATA INTO COMPUTER WHICH TRANSLATED IT INTO GEOGRAPHIC POSITION.
Technical
PART OF EARLY SPACE-BASED POSITIONING SYSTEM, USED IN NAVIGATION, SURVEYING, ETC. IT MADE USE OF DOPPLER EFFECT MEASURED BY TRACKING SINGLE SATELLITE, & THUS WAS FAIRLY SLOW. IT WAS SUCCEEDED BY MUCH FASTER & MORE PRECISE GPS SYSTEM BASED ON RADIO SIGNALS FROM SEVERAL NAVSTAR SATELLITES.
