Abstract:

This manual describes procedures for operating the Transit Orbit Improvement Program on the IBM 709 and 7090 Data Processing Systems. Input and output are stressed the programs are treated essentially as black boxes. To describe input-output, liberal use is made of sample card listings. A typical set of data from Transit 2A is presented together with output listings from a normal run. To describe operations, a comprehensive countdown chart is presented followed by a troubleshooting section based on experience to date. Since the programs are of an experimental nature they contain many diagnostic features not used in daily orbit improvement reference to them is omitted here but may be found in the program listings. Finally, various presets in the program have been adjusted empirically to the data processed from the satellites 1960 Gamma 2 and 1960 Eta 2 Transit 1B and 2A. Should the user wish to use these programs for processing data of different characteristics, he is likely to find the necessity for changing preset values and operating procedures.
