DIGITAL OPTICAL TRACKING SYSTEM
Abstract
This space-position measurement system comprises two Askania Kth 53 cine-theodolite instruments with digital encoders mounted externally on their azimuth and elevation axes, readout electronic equipment including multitrack tape recording and playback subsystems, and a conversion subsystem for entering digital data in a Burroughs 205 computer. Digitally, angular position readings are possible to !1 part in 32768, and by a small modification, ca be extended for azimuth angles to !1 part in 65536. Sampling rates are 1, 2, 4, 8, or 16 per second. Instrument dial angular position capability is five seconds of arc, for which film recordings are available for visual scanning. Time, recorded in binary code, is accumulated each 2-second period in groups of eight frames each. Time correlation exists within the system, and is possible with external systems.
