7.6 Specific Requirements On Tests
7.6.1 General
AVI-2137/CREATED/R
All specific support test equipment must be compliant with the intended purpose, within its useful life
and calibration.
AVI-2138/CREATED/R
For tests performed with automated test scripts, batch files or generally with software, the test
procedures and reports shall provide the relevant test-step information in the software source code or
in the printout/protocol of each test software item. The test report shall include configuration control
information (compilation date, checksum, version or revision number, etc.) for each software item
used for the reported test.
7.6.2 Avionics SCOE Functional Tests
AVI-2140/CREATED/R
The Avionics SCOE functional tests shall verify the operation, connectivity and functionality of each
supplied Software Module and Spacecraft Interface.
7.6.3 Avionics SCOE to EGSE Interface Tests
AVI-2147/CREATED/R
The proposed test schedule shall include verification of the Avionics SCOE to EGSE Interfaces:
• Avionics SCOE to CCS.
• Avionics SCOE to RTS
For the Avionics SCOE to CCS Interface, this may be achieved with the use of hardware stubs simulating
the missing EGSE (and initially for the RTS interface).
AVI-2149/CREATED/R
For the case of the RTS, final testing of the Avionics SCOE to RTS interfaces shall include testing
with an actual RTS in the loop.
AVI-2150/CREATED/R
As a minimum these tests shall verify the operation of and bench-mark the achieved latency times, of:
• RTS Models commanding Avionics SCOE outputs to the Spacecraft.
• Updates at the Avionics SCOE inputs being detected by the RTS Models.
• MIL-STD-1553B and SpaceWire BUS transfers.
AVI-2151/CREATED/R
Final testing of the Avionics SCOE with the RTS shall be conducted on site at Astrium Ltd.
