342 Topcon Postioning is now offering a sophisticated surveying tool in the shape of an auto-collimating total station for surveying professionals looking for a motorised solution. The firm says that this rugged waterproof total station benefits from the latest TSshield technology for advanced security and maintenance. The system can also be upgraded to Autotracking when the customer is ready to advance further to robotic applications. The GT-503M can be used for Tunnel Guidance and Periodic Monitoring applications.


Key features include direct drive motors capable of turning 85°, in a small and lightweight package that is auto-collimating. This also features the LongLink Communications system with a range of 300m, advanced angle accuracy and the TSshield advanced security and maintenance package. The system offers an 800m non-prism range and a 4,500m prism range, as well as a laser pointer and sunlight readable display.

The new dual SIM module allows the customer to insert their own data SIM card in the GT-503M total station to communicate directly to MAGNET Enterprise. The telematics card installed can communicate to the TSshield servers, which can then review if the total station has any existing error codes, the version of the firmware that is installed, as well as the total station geographical location. From this information, a message can be sent to the total station and advise the operator if further action is available or necessary. The new dual SIM module allows the customer to insert their own data SIM card in the GT-503M total station for real-time site communications.

The GT-503M can find a prism and lock within the field of view simplifying the steps for the operator to find the prism. There is no need to focus the GT-503M to find the prism.
