Book excerpt: This report cicals with the problcm of determining the trajectory of a spacecraft from on-board optical measurents without a priori information. Only sufficient information to determine the trajectory is used, and it is assumed that this preliminary estimate will be improved later by the use of differential corrections and redundant data. Five basic types of measurements, representing instruments considered feasible or within the state of the art, are considered. The effects of random and bias type measurement errors and interpolation errors arising from nonsimultaneous measurements are analyzed. Only observations of the central body and two stars are considered. Within certain limitations all five types of measurements will give satisfactory results. Two important factors discussed in the report are the proper choice of stars and the calibration for eliminating bias errors.

This book was released on 1971 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Onboard procedures requiring only simple calculations have been developed for midcourse and approach guidance for translunar trajectories. For midcourse guidance the procedure relies solely on an optical range measurement. The approach-guidance procedure requires a star-to-body measurement and may require a range measurement, depending on the distance to the moon. For both procedures the velocity-correction vector is applied in a fixed inertial direction. In the approach-guidance procedure either one or two guidance maneuvers are applied, depending on the accuracy desired and tile distance to the moon. An error analysis showed that perilune radius can be controlled to a onesigma accuracy of about 30 km.
