The Apollo/Saturn S-II telemetry data processing systems are described from concept through development and fabrication. The systems are large-scale, dual computer-controlled systems that accept PCM, PAM, PDM, FM/FM, and FM data and are capable of processing raw data for display as time-history digital plots, tabulations, or oscillograph recordings. Stored-program decommutators which eliminate distribution patchboards for each data word are integrated into the system, thus, providing a flexible means of routing data with a minimum of human error. High-speed digital plotter/printers produce final annotated plots of selected channels for engineering reports, Small general-purpose computers are integrated in the system to establish data flow discipline. The computers function as an entry for operation control and for preparation and loading information to all programmable equipment, interconnecting digital equipment, process monitoring, and diagnostic testing of subsystem operation. Versatility of computer or manual systems control provides an optimum telemetry data processing environment. Advanced techniques are briefly discussed as related to these and other telemetry data processing systems.

Double integration of the longitudinal acceleration of a sounding rocket is useful as a simple means of determining its trajectory. Reasonably accurate altitude calculations can be made by this method except when surface winds alter the launch angle of the rocket. Surface wind velocity corrections can be introduced to correct velocity and position information in the horizontal direction, but accurate wind correction data is difficult to obtain for all rockets. A special solar aspect sensor was designed to be used with a commercially available magnetic aspect sensor for rocket attitude determination. This attitude data allows the longitudinal acceleration to be broken more accurately into three vector components. A feasibility study of the aspect system was made using three Aerobee-150 rockets. A digital computer trajectory program was written to utilize aspect and acceleration data for trajectory analysis. It is evident that rocket attitude data is a useful supplement to the longitudinal acceleration data for trajectory determination. More accurate magnetic aspect data is necessary, however, to refine the longitudinal acceleration technique.
