DESCRIPTION
The K6-12 Work Station is designed for automatic verification of a user GLONASS/GPS navigation equipment by means of transmission of coordinates, time and frequency units.
The K6-12 Work Station may be used in metrological laboratories, services of legal metrology, repair shops for testing and maintenance of a user navigation equipment.
SPECIFICATIONS
The Work Station provides:
