A7 prism: Topcon Positioning Systems

A new, lightweight, compact, robotic prism series and mounts have been announced by Topcon Positioning Systems (TPS).

The A7 prism series supports the ability to mount a GPS receiver on top of the A7 prism for an integrated robotic and GPS rover solution. Additional accessories, including a regular top mount and a side-mounting option for the RC-3R, are also now available.

Multiple configurations are now available with the A7 series including:

* The integrated GPS mount and A7 prism pole can be used in a GPS network for real-time GPS coordinates that a robotic instrument then uses for resection;

* With a full-size canister prism and RC-3R side-mount, the unit can take difficult prism shots through vegetation, wetland flag markers, and other obstructed views

* The A7 can also be mounted inverted on a prism pole. By having the ability to mount the prism closer to the ground, construction stakeout can be done with greater precision

* The RC-3R side-mount can be connected at several angles, allowing very high or very low vertical angles of transmission.
