Ongoing Activities:

Attitude Training - The OE's have begun training the remainder of the FOT on
attitude determination.

Clock Calibration - A new TPOCC release to address the clock calibration
issue is under development.  String 3 development testing is expected to
begin mid-October.  Three DR's will be delivered in this release.  
	DR 22309 - Extend the number of years in the Clock Calibration file.

	DR 22411 - Clock Calibration Numerical Error
	DR 22446 - Increase precision of offset in clock report.

RIONET - The transition to the RIONET on String 3 will occur after the next
ROBOTT delivery.  

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

Automation - The ROBOTT SPS release test summary report has been finalized.
The next full ROBOTT release is not expected until after the TPOCC/Clock
Calibration release.
