With the completion of the NRL evaluation of the experimental model of the Satellite position Prediction and Display equipment SPAD, efforts have been directed toward the consideration of an operational version of SPAD. One possible equipment configuration, which would lead to a substantial savings in cost and development time, incorporates the SPAD functions into the Naval Tactical Data Systems NTDS. By time sharing the NTDS computer through suitable programming, one of the display consoles in an NTDS facility could be used to present a SPAD display without interrupting service to the other NTDS displays. This proposal is based on the premise that no hardware modifications or additions are to be made to the NTDS equipment except for changing certain labels. Also the time required for switching a display console between NTDS and SPAD should be kept to a minimum. It appears that all of the original SPAD features can be incorporated into the NTDS equipment without any conflict with these ground rules. The NTDS-SPAD concept will give an NTDS-equipped ship a satellite display capability at minimal additional cost. Author
