- W1978441049 abstract "The presence of extraneous light sources has often represented a problem to the reli-able operation of stellar sensors. The Bendix Star Sensor Assembly (SSA) is designed to accurately detect faint stars (+4 visual magnitude) with the existence of bright objects (sun, moon, etc.) near the field of view. A measurement was needed of the SS's off-axis light attenuation when operating as close as 40° to the sun. This was accomplished through careful control of a 16 by 10 meter solar-thermal-vacuum chamber. Background scattered light was minimized and mapped enabling accurate photometric testing with the SSA under going simulated solar impingement. The test results showed that the SSA will provide a minimum system attenuation of 10<sup>13</sup>:1 when operating at 40° to the sun. This paper sum marizes the test concepts and techniques formulated and the problems resolved in proving that a) such a test was indeed feasible and would reliably represent an accurate measure of SSA performance and b) the SSA did, in fact, perform to its requirement." @default.
