Common datum or common survey is critical for successful employment of TA WLR assets. The specific survey data required for each TA WLR system is described as follows: AN/TPQ-36: Grid zone. Site location (UTM coordinates within 10 meters CEP). Distance from near stake (radar location) to far stake (orienting point). This distance should be at least 250 meters. The minimum distance is 100 meters. However, the further out the distance the better the accuracy that the system will report. Azimuth from near stake to far stake (0.4 mil PE). Vertical angle from near stake to far stake (0.5 mil PE). Altitude of the near stake (10 meters PE). AN/TPQ-37: Grid zone. Site location (UTM coordinates within 10 meters CEP). Distance from near stake (radar location) to far stake (orienting point). This distance should be at least 250 meters. The minimum distance is 100 meters. However, the further the distance the better the accuracy that the system will report. Azimuth from near stake to far stake (0.4 mil PE). Altitude of the near stake (3 meters PE). AN/TPQ-53: Grid zone. Site location (UTM coordinates within 10 meters CEP). Distance from near stake (radar location) to far stake (orienting point). This distance should be at least 250 meters. The minimum distance is 100 meters. However, the further out the distance the better the accuracy that the system will report. Azimuth from near stake to far stake (0.4 mil probable error (PE). Vertical angle from near stake to far stake (0.5 mil PE). Altitude of the near stake (10 meters PE). AN/TPQ-50: Grid zone. Site location (UTM coordinates within 10 meters CEP). Distance from near stake (radar location) to far stake (orienting point). This distance should be at least 250 meters. The minimum distance is 100 meters. However, the further out the distance the better the accuracy that the system will report. Azimuth from near stake to far stake (0.4 mil probable error (PE). Vertical angle from near stake to far stake (0.5 mil PE). Altitude of the near stake (10 meters PE). MODULAR AZIMUTH POSITIONING SYSTEM 3-43. The AN/TPQ-36(V)8 and AN/TPQ-37(V)8 radars are equipped with the Modular Azimuth Positioning System (MAPS). MAPS provides required survey for these systems. However, MAPS requires external survey support to provide the initialization data and update points required for operation. MAPS
