Digital Tachograph DTCO 3283 for Accurate GNSS Navigation Measurements

Tachographs are designed to measure navigation parameters by signals of navigation spacecraft of global navigation satellite systems (GNSS) GLONASS/GPS, the number of electrical impulses from motion sensors, determine on their basis the coordinates, speed, distance travelled by vehicles, time interval, synchronisation of the time scale of the internal reference oscillator of the tachograph with the time scale of the tachograph's SCSI unit when operating on GNSS GLONASS/GPS signals.
