Speed Advisory Trailer Signs (SATS) or VMS Radar Signs - these are trailer mounted, self-powered (solar) Variable Message Signs equipped with a radar speed detector which can then display the detected speed readout and log these detected speeds which can then be emailed for later analysis. These signs are fully programmable, feature packed full matrix graphic displays. They can be used for traffic management on road projects, mining sites, in school zones, car parks, or to notify of changes in speed zones, and other applications.

The Data Signs VMS S5 can be used as a speed advisory sign, or it can be used as a small VMS trailer.

Performance: Detection Range is typically 90+ m (300+ feet) for compact vehicles on open and level road with radar mounted at least 1.5 m (5 feet) high and pointed straight into oncoming traffic. May vary with installation and road conditions. Detection range specified is typical for speeds between 10kph and 110kph.

No Ongoing Calibration Required: During the manufacturing process, the speed measurement accuracy of each and every radar by an automated test system by using a digital Doppler target simulator.
