CamNav
GPS encoding for camcorders

CamNav puts technology that had previously been the preserve of big budget installations, into your hands, literally.

Taking GPS positional data from a GPS antenna and receiver (supplied), CamNav ‘attaches’ this data to your video footage via a single lead into the mic input of your camcorder, it doesn’t matter whether it’s digital or analogue.

CamNav is supplied with its own high specification GPS receiver, GPS antenna, data and audio modulation leads for encoding and decoding. An RS 232 output port allows direct interfacing to a PC or other serial data devices. For recording other RS232 data, an auxiliary port allows for input of ASCII messages at 4800 baud to be similarly recorded.

Alternatively, data from an external GPS receiver can be used with the stand-alone CamNav (no internal GPS).

CamNav integrates seamlessly with the CamNav Mapper system to plot the position of the footage onto a laptop or PC based map.

CamNav can be used in both recording and live transmission* applications
