Abstract:

Development of the ID-551APN-105 Earth Rate Directional Reference ERDR is described. Two models were constructed. The prototype model differs from the developmental model in that there are only two units instead of four, due to improved packaging. Improvements of the electrical configuration, such as the use of twospeed integrators, were made in the prototype to improve the performance over that of the developmental model. Both systems were subjected to bench testing to determine compliance with specifications. A minimum flight test program was followed to further evaluate the system performance. Results of the flight test program were on the whole successful. Most problems were solved and the ERDR-Doppler system is capable of operating with the expected accuracies. Author
