Tracs COM System

The TracsCOM system provides a general purpose, high speed intelligent data link that operates through VHF and UHF radio bands. It can be used for a range of applications, particularly those where highly reliability, speed and data integrity are required. TracsCOM is housed within a lightweight moulded enclosure that is rated to IP65, making it suitable for use in demanding environmental conditions. A marine standard, IP67 rated version is also available. Power output can be 10mW, 500mW or 2W. For more details and technical specifications, please follow the link to the DGPS 4U website.


AsteRxi Satellite Navigation Systems process both high quality GNSS measurements and IMU (Inertial) measurements in order to generate an enhanced integrated position. Dual-frequency GPS/GLONASS receivers are therefore capable of giving extremely precise positions, even in shadowed environments where GNSS-only receivers typically fail. AsteRxi systems also provide attitude information such as heading, pitch and roll, giving you a more complete view of plant and vehicle condition and whereabouts. These systems are available in both dual- and single-frequency configurations.
