Subject: 1 PM status meeting MA2 TCXO Anomaly: HSTAR 13152

Meeting today in S107A at 1:00 as a follow up on the MAT 2 anomaly seen
late last week.ˆ Due to the holiday, folks were asked to stand down and
today is sort of an investigation kick-off meeting.ˆ We will review the
observables and discuss future troubleshooting. ˆ Charts should be
posted to the anomaly briefing page prior to the meeting. We will use
the anomaly call in number for audio and Meeting Place for charts. ˆ

ˆ Flash Report:ˆ
MA2 TCXO Anomaly Status Briefing:ˆ HSTAR 13152 ˆ An MA2 TCXO Anomaly
Status Briefing was held on Saturday December 24thˆ 2011, and authority
was received to continue with non-coherent (non-COHO) supports on MA2
through 11 am. EST Tuesday December 27.ˆ The following information
summarizes the anomaly briefing: ˆ



2.ˆàˆàˆàˆàˆàAction Items:

ˆà
Action 1 òÀÓ Change COHO passes to non-COHO through 11 am. EST Tuesday
December 27.
Assigned:ˆà FOTˆàˆà Status:ˆà Openˆàˆà Required by:ˆà Dec-24
ˆà
Action 2 òÀÓ Establish production of Two Line Element (TLE) sets via Radar
skin-track.
Assigned:ˆà FDFˆàˆà Status:ˆà Openˆàˆà Required by:ˆà Dec-26
ˆà
Action 3 òÀÓ Update, test, and deploy Acquire proc change to add Mode 2 GCMR
before the first forward reacq.
Assigned:ˆà Proc WGˆàˆà Status:ˆà Openˆàˆà Required by:ˆà Dec-29
ˆà
ˆà
3.ˆàˆàˆàˆàˆàWaiver Approvals:

ˆà
None.
ˆà
4.ˆàˆàˆàˆàˆàDiscussion/Agreements:

ˆà
As stated above, authority was received to continue with non-coherent
(non-COHO) supports on MA2 through 11 am EST Tuesday December 27.ˆà As a
result, tracking data will not be collected through the period and, in the
event an MA2 contact fails to acquire as planned, real-time engineering
data will be lost since the Acquire proc would issue COHO GCMRs in
response to late acquisitions.ˆà It was agreed that impacts to HST
operations due to the loss of tracking data will be negligible during the
period.
ˆà
The FDF agreed to pursue production of TLE sets via Radar skin-track
starting on Monday December 26.ˆà They will also assess TLE accuracies.
ˆà
It is not currently known whether the anomaly is the result of an HST
hardware issue or an interfering carrier.ˆà Additional investigation will
resume on Tuesday December 27.
ˆà
It was recommended that the Acquire proc be updated, tested, and deployed
to add a Mode 2 GCMR before the first forward reacq.ˆà This will be pursued
next week by the Proc WG.
ˆà
5.ˆàˆàˆàˆàˆàLiens:

ˆà
None.
