Abstract :
The new station delay calibration system, to be implemented in the VSL TWSTFT station, will perform a complete calibration of the ground station delays. The new dual-stage quad-mixer satellite simulator promises improved repeatability and less susceptibility for environmental influences. The true power of the system is the multidirectional transceiver operation within the satellite simulator. This allows including additional measurement paths, enabling absolute measurement of the path delays. Hence, the new station delay calibration system is completely stand-alone and no additional, time consuming, periodic VNA calibrations are required.
