16 February 2016 ATP 3-09.02 D-1 Appendix D Azimuth Determining System (ADS) The azimuth determining system (ADS) is currently used by the USMC as a means of hasty survey. This is an approved capability for Army units if they have obtained the proper equipment. The ADS is approved by TRADOC Capabilities Manager (TCM) Brigade Combat Team (BCT) Fires; however, units must use their own funds to purchase the equipment. AZIMUTH DETERMINING SYSTEM HASTY SURVEY CAPABILITY D-1. The ADS is a hasty survey capability that uses two (2) DAGRs in conjunction with each other (see figure D-1). The ADS is properly set-up and initialized over the Orienting Station (OS). The azimuth from the OS to the EOL will be determined by transporting the “master” DAGR from the OS to the EOL. Master Slave Figure D-1. Dual DAGR configuration D-2. The operator sets up over the OS and initializes the system. He disconnects the “master” DAGR from the “slave” DAGR and sets up the master over the EOL. First option, a second tripod with antenna pole receptacle mounted on it, may be set up over the EOL connecting the master to the antenna pole receptacle upon arrival. Second option, if the operator has a telescopic range pole with an attached circular leveling bubble, he may attach the master to the range pole after disconnecting the data cables, walk to the EOL, steady and level the range pole by stabilizing with his body. D-3. Once the EOL data is stored in the DAGR, the operator re-connects the “master” to the “slave” at the OS. The ADS will then compute a single continuous phase line over the orienting line and provide an absolute position and elevations for the OS and EOL and a processed azimuth to the EOL.
