Activities:

RIONET - Testing and configuration continue for String 1 on the Restricted
IONet.  DSN monitor data is not yet being delivered.

ROBOTT - ROBOTT v1.0.3 upgrade will be installed on String 1 on Monday
07/09/2007.  This upgrade is needed for ROBOTT to work on the Restricted
IONet.

Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the
Library on April 28, 2006.  Installation in the ACE MOC will not occur until
after the MOC is converted to the RIONET.

DSN/SPS/FDF - FDF is now delivering a 12 week predictive ephemeris which
will satisfy the DSN SPS requirements.  However, the original problem (ACE
viewperiod files starting in the future) was fixed when SPS corrected their
own timer configuration.

Planning continues for integrating ACE operations into a multi-mission ops
center (MMOC).

============================================================================
Anomalies:

None

Update on AR#G07-0055 - Problems with String 2 were fixed by replacing the
front end workstation motherboard.  Replacement parts, however, are becoming
scarce.
