SHIRAN: GEODETIC SURVEY SYSTEM, ELECTRONIC AN/USQ-32(XA-1).
Abstract
SHIRAN is composed of an airborne Distance Measuring Interrogator Set AN/APQ-105(XA-1) and four or more ground-based Distance Measuring Transponder Sets AN/TPQ-24(XA-1). The airborne interrogator ranges simultaneously to up to four ground transponders and records time-indexed range data on magnetic tape in conventional computer format. Maximum slant range to any one transponder is 500 nautical miles, with line crossing accuracies in the order of =10 feet (PE). Ranging operation may be synchronized with photomapping camera shutters for controlled photography missions. This report fully describes the system and the equipment that was developed. The operation of the equipment is explained at the block diagram level. Also described are the rf equipment items especially designed for SHIRAN under subcontract, and the modifications made to SHIRAN equipment to enable its use in the AN/USQ-28 program. The extensive flight tests and comprehensive environmental tests conducted on the developmental equipment are covered in detail. Test results confirmed that all design goals were met.
