[Isocops] [Ibexops] IBEX AUWA Contact DOY 269 @ 1100 UTC

[Dan Hobel]

John and Lisa,

Could I get some more information on these AUWA Doppler issues?  Could you please provide the following:

-        Reason for failure

-        Current Doppler bias at AU, AK, HI

-        Current standard deviation at AU, AK, HI

-        Historical Doppler bias at AU

-        List of good vs bad AU supports over the past few months

-        Have you confirmed both HS and LS UTDF files demonstrate the same bias

-        Any other relevant information like ascending/descending, spacecraft antenna, downlink data rate, expected range rate/Doppler, etc.

I am trying to understand and isolate the issue to equipment, configurations, or references so these answers will help us focus on the issue.

Thanks,
Dan

Hello again everyone,

The AUWA 1400 UTC backup tracking pass also failed for Doppler measurements and is causing many of our tests to fail. FDG is calling both the 1100 and 1400 AUWA passes failed contacts.

Thanks,

Good morning everyone,

The Australia 1100 UTC ascending contact failed for Doppler. There is a backup tracking contact also with AUWA at 1400 UTC.


Thanks,
