The activities under the SAAF project address the ancillary functionalities and autotest capabilities that coupled with a power producing SAS (Solar Array Simulator) would provide full simulation and verification of the power and dynamic aspects of a spacecraft Solar Array (SA), see figure below:
SAAF Conceptual Diagram
The basic functionality of SAAF can be decomposed into three principal blocks:
Key challenge was to keep the design generic enough to satisfy the needs of both telecom customers in Europe and USA.
The product provides a major reduction in validation time for telecom customer during AIV and re-configuration of facility for different S/C.
The Autotest capability provides satellite integrators with an automated tool for verifying the performance and safety of the SAS equipment and harness before it is connected to the spacecraft. It provides the following major features:
The SA Initial Deployment simulation capability provides satellite integrators with the ancillary functions related to the initial deployment of the spacecraft SA, namely:
The SA Through-life Simulation capability provides satellite integrators with emulation of the SA sensors and actuators (aside from provision of power itself) which operate during the nominal power harvesting phases of the mission:
As described in Contract and CCN1.
Current status is completed.
