Abstract : The objective of this program is to determine the feasibility of novel laser techniques for Doppler optical navigation. The performance goal is the measurement of ground speed of a satellite, travelin. at a velocity of l0,000 meters per second at an altitude of 300 miles, with an accuracy of 5 meters per second. Doppler measurements, using a laboratory Dppl r simulatr, verified that more tha one complete cycle of Doppler shift must be .eejated by discrete jeflecting elements for Doppler freu ncy to be measured accujately. OKPERATION OF A THERMELECTRICALLY COOLED GALLIUM-AJSENIDE LASER TRANSMITT R WAS DEMONSTRATED. This refjigeration t c;nique mak s injection lasers pjactical. (Author)
