All Aquarius electrical interfaces have successfully been connected to the SAC-D Service Platform (S/P). The S/P has now replaced the Aquarius Electrical Ground Support Equipment (i.e., all the non-flight test equipment that was used to connect to Instrument to power and communicate) for the operation of the instrument. Thus Aquarius is now receiving power and commands from the S/P and Aquarius telemetry and hi-rate data are being returned via the S/P. Telemetry and data files downlinked by the S/P match the files collected from an Aquarius direct-access test port, verifying the data flow from the instrument through the S/P. These successful tests represent significant milestones in the Aquarius Electrical Integration process.
