Flight software uses checksum to validate the uplinked data . Executive (40 Hz process) sends command to proper destination, either hardware or software . Each block load contains the address in memory to place the data . ... Checksum on block load is verified before block is stored in memory . Block loads can be designated for any one of three stored command processors . ... Most stored commands are uplinked from the ground and executed once . ... Previous slide . Next slide . ...

... The location of the +1st spectral order relative to the source positions in the direct imaging filters F098M and F105W are determined, field dependent trace and wavelength solutions are derived, and the absolute throughput is quantified. ...
