Earth station qualification is necessary to ensure the performance of the equipment used by the user's earth station fully complies with satellite network operation requirement, in particular, the antenna radiation patterns, the modulation, spurious and inter modulation characteristics, and frequency and power stability.

Whenever an AsiaSat user needs to build a new earth station, expand or upgrade its satellite networks, or replace new network equipment including antennas, amplifiers, receivers, modems and test equipment, AsiaSat engineers work with the user's network operation centre or selected uplink provider to confirm that the design and operation of the network comply with AsiaSat's requirements. Additionally, AsiaSat engineers conduct visits to the customer's uplink site where they also test and qualify the customer's earth station.
