Abstract
A system configured for rough localization of moveable cooperative targets. The system includes at least one laser tracker, having a moveable upper part connected to a base part, an optical target rough location detector automatically detecting a rough location of a cooperative target, a target fine position detector automatically detecting a fine position of a cooperative target within a fine position field of view, motors for changing an orientation of the moveable upper part, a motor controller, and a computer, a first and a second radio frequency telegram (RFT) transceiver (RFTT) anchor-module, wherein each RFTT anchor-module's position is referenced to the laser tracker, a cooperative target associated with a RFTT tag-module and each of the RFTT tag- and anchor-modules an evaluation unit configured for determining a RFT-transmission specific parameter based on the transmission of RFTs between the RFTT anchor- and tag-modules and providing said RFT-transmission specific parameter to the computer.
