RE: 2 P3D questions
Hello, All.
I agree with Mark and get the SAME MA using Nova as is displayed on the
downloaded telemetry, with CRCC correct. This is with my using Ken's
dataset number 4 for Keps.
They are:
Satellite: AO-40
Catalog number: 26609
Epoch time: 00328.20006944
Element set: 4
Inclination: 6.4214 deg
RA of node: 245.2971 deg
Eccentricity: 0.7351666
Arg of perigee: 180.5141 deg
Mean anomaly: 180.0042 deg
Mean motion: 2.03021569 rev/day
Decay rate: 7.51000e-09 rev/day^2
Epoch rev: 16
Checksum: 246
This says to me two things:
1. Nova is doing the MA calculation correctly and can be used to tell when
to listen for the 2400 MHz beacon.
2. Dataset 4 is still the correct set of keps to use. I make this latter
point because this has been an item of recent discussion. Dataset 4 also
seems to accurately predict AOS and LOS here.

Cliff,
For what it's worth, at 17:48 UTC, Nova for Windows and the live telemetry
data show the same MA.
