ABSTRACT


FOS Binary Sea.rcb and Firmware Tazget Acquisition was tested under
tbe newest (3.9) version of flight software at LMSC. All cotrections
of the previous version of flight software TA were verified, and no
new bug. ware discovered.

The ta.rget acquisitions were simulated by illumina.ting the science
apertures with the blue LED~ in the same way that aperture
acquisitions will be done in flight. The largest errors were 16% of
the a.perture elze in the Y direction, and about 30% of the aperture
size in X. These errors are due to the non-uniformity of the
illuznination from the LED., and the large size of the ecience
aperturee, and arc satisfactory.
