Subject: ACE Weekly 6_30_99

ACE operations were nominal over the past week.

Over the past month, the FOT has noticed delays in commanding during the
precalibration phase with the DSN station. During realtime, there has been
no impact to commanding or telemetry.

Coordinated with JPL Comm and IP NOCC to test command system and determine
the nature of the observed delays in sending TEST blocks and NO_OP
commands. The results of the test were indeterminate. Possible cause may
have to do with ISIS.
IP NOCC is continuing investigation.
