Description
The Trimble Active Track 360 (AT360) Target is a 360° active target used for robotic surveying. It is designed to be used with the Trimble S3, S6, and S8 Total Stations as well as the Trimble VX Spatial Station, but it can also be integrated with the Trimble V10 Imaging Rover.
AT360 has an integrated 360° active LED ring for tracking and reflective foil for distance measurements. The LED’s emit one of eight unique ID channels which can be selected from the panel to ensure that the correct target is tracked every time on a site where multiple targets are used. This unique Trimble technology also assists in maintaining target lock where adverse tracking conditions may exist and eliminates the potential for false lock onto other reflective surfaces.
The Trimble Active Track 360° Target is powered by a single lithium-ion battery that can last up to 12 hours in normal operating conditions. It can also be powered by an external power supply via cable connection for applications that require permanent installation.
