Topcon A7 prism series and mounts provide multiple configuration options

A new series of lightweight, compact, robotic prisms 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, and 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.
