Method and installation for calibrating an airborne goniometry apparatus

An installation for calibrating an airborne goniometry apparatus, said installation comprising a generator, wherein said generator comprises a calibration generator, configured to share with said airborne goniometry apparatus a calibration sequence and a start time of said calibration sequence, said installation comprising:

• a first clock receiver, coupled with said airborne goniometry apparatus, configured to receive a clock signal and provide a clock to said airborne goniometry apparatus, and
• a second clock receiver, coupled with said calibration generator, configured to receive a clock signal and provide a clock to said calibration generator;
• wherein said first clock receiver and said second clock receiver are configured to receive the clock signal from a same source, external to said airborne goniometry apparatus and to said calibration generator, and to provide an identical clock, wherein said identical clock comprises a reference clock.
