Thanks Kayton.

So the tracking data post-anomaly looks good too. That's excellent news. I'm pretty sure that means the downlink is coherent. Let me know if you or others at L3Harris disagree.


Also, Tim took a successful test pass with AK today to validate the fixes that SSC made. So he scheduled two contacts for tomorrow (Friday) morning and hopefully we can get good tracking data from them too. We've shifted the HI01 apogee contact on Monday 27 Feb later because it conflicted with the time slot earmarked for the follow-up ARB (10:00 am eastern). Again, we hope it will provide more good tracking data.

Before the next perigee and potential Master Reset due to the 18 day command loss timer on 4 March, if we decide to perform a Firecode Reset that could result in no downlink for a while, would ~30 minutes of tracking data before the reset be helpful in providing an orbit determination that's as up to date as possible before losing visibility?
