The Telenav GPS OSD Module is a self contained device with Video processor and high accuracy GPS receiver module that provides a video OSD overlay function on a dedicated video outlet.

An internal high sensitivity GPS receiver provides the position overlay data and also the NMEA 0183 RS232 data via a standard serial connector

Interfacing is simple and unambiguous whereby the camera video is applied to the input video BNC connector. Video with the OSD of GPS coordinate text is available on the Video Output OSD BNC.

Two additional buffered video outlets, without text, are available to distribute the camera video to other devices such as a monitor or video recorder.

The GPS antenna couples to the GPS TNC connector on the module.

Power for the module is via an external dc power connector or from an optional V-lock li-ion battery cradle mounted on the top of the module.
