DOPPLER OPTICAL NAVIGATOR.
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)
