This report describes the results of a preliminary design and analysis of a new spacecraft navigation system which is designed to operate autonomously in earth orbit. The sensor, known as the Space Sextant, in combination with an on-board computing system, will be capable of determining the spacecraft's position and attitude for any orbit in cislunar space with comparable accuracy. The Space Sextant is basically an angle measuring device employing two connected and independently servoed trackers which are capable of approximately 0.5 arc second included angle measurement accuracy. An estimated navigation accuracy of about 800 feet is obtained by measuring angles between the moon's bright limb and the bright stars. An estimated attitude accuracy of about 0.3 arc seconds is obtained by referring the measured star directions to two orthogonal, body-fixed reflecting surfaces.
