SATELLITE TEST FACILITY
Measurements taken with the Test
Laboratory included the effective radiated power of the spacecraft under various access
conditions, the receiver sensitivity and transfer characteristics, the performance of the
beacon transmitter and of the spacecraft power-sharing circuitry as well as recordings of
amplitude and phase jitter. The phase delay through the spacecraft transponder was also examined.
The accuracy of the in-orbit tests was of the same order as that obtained by the spacecraft manufacturer prior to launch. The degree of accuracy was achieved by continuous calibration and adherence to a carefully designed test protocol.
The test facility was also used to:
- Measure the radiated power of remote earth terminals, using any convenient satellite as a link.
- Carry out tests on other nation spacecraft on a repayment basis.
- Support the R&D work of associated groups.
