Abstract:

A feasibility study to design a system for determining vehicle attitute by means of radio frequency techniques was conducted in accordance with the provisions of Exhibit A to PR No. 63-211. Various techniques to perform the attitude determination were evaluated. It was concluded that the use of an inverted interferometer with transmitter installed on the vehicle would meet the system requirements. Using at least two ground stations, the yaw, pitch, and roll axes of the vehicle can be measured to an accuracy of 0.1 degree during the early launch phase. In subsequent phases of flight the accuracy of yaw measurement is reduced. A detailed antenna analysis was provided by Smyth Research Associates on subcontract to Cubic Corporation. This analysis estimates the magnitudes of the measurement errors contributed by the antenna baseline on the vehicle. The operation of the transmitting interferometer is examined in detail in this report and preliminary system design parameters are established. Recommendations are given for areas requiring further study. Author
