Tracs-Cub Mk II


The Tracs-Cub Mk is a low cost, high performance EGNOS/WAAS GPS smart antenna designed specifically for precision farming applications.

The unit maintains the accuracy standards the industry has grown to expect from the company by utilising a Thales 12 channel GPS receiver designed to receive free differential EGNOS/WAAS correction messages. The unit also provides a dedicated RS232 port for optional external RTCM messages.

The light-weight, plug and play unit provides NMEA RS232 and J1939 CAN bus messages for flexible interfacing to agricultural vehicle systems. It can be used in conjunction with all Tracs agricultural products including the Tracs-Bar and hand-held data logger.

An optional magnetic mount kit enables the antenna to be removed and reinstalled quickly and securely on a variety of vehicles.

Features include:
Internal 12 channel EGNOS/WAAS differential receiver
RS-232 and CAN J1939 ports
Optional external RTCM input
Protected against vehicle power supply transients
Optional magnetic mount
