A position measuring system for a remotely controlled video camera was designed and built. The camera is intended to be used with the modified Advance Development Model of the AN/SAR-8 Infrared Search and Target Designation System (IRSTD) in use at the Naval Postgraduate School. The video data collected by the camera will be correlated with the infrared data from the IRSTD to develop a background data base that will be used in the development of signal processing algorithms. The measurement system uses two Hewlett Packard HEDS-6000 incremental optical encoders, two Motorola MC68705U3 microprocessors and two digital display devices to measure and present the camera's azimuth and elevation angles to an operator at a remote location. The azimuth can be measured over a range of 360 deg with a resolution of + or - 0.0213 deg and the elevation can be measured over 24 deg with a resolution of + or - 0.138 deg. The resolution is limited primarily by hysteresis, which is due to the backlash in the gears between the transducers and the axes of interest.
