Hi,
I only just regained access to Seesat-L so I don't know if
Ron Lee already posted this orbit. I obtained the following
Chandra orbit data from the Chandra control room folks - I hope someone
can generate TLEs from these.
Post IUS orbit (where we are now)
Epoch 99204 13:48:51
Alt 330.23 x 72030.56 x 28.4528
SMA 42558.527
Ecc 0.842373
Inc 28.4528
RAAN 196.2671
AOP 270.0155
True Anom 119.3190
Mean Anom 14.5069
Period 24.2710 hr
Planned post IPS 1 orbit (after 9.11pm EDT this evening)
Alt 1200 x 72023 x 28.44
SMA 42990.1355
ecc 0.823711
Inc 28.4448
RAAN 196.0098
AOP 270.3411
Mean Anom 180.5498 (no epoch given!)
Period 24.6412 hr
Burn times currently planned:
IPS-1 206/01:11:27 for 5min 00 sec
IPS-2 207/01:45:05 duration 11:03
IPS-3 212/22:27:21 for 21:07
IPS-4 214/04:46:30 for 11:23
IPS5 216/20:27:07 for 01:45
Chandra is stable and returning data, but the data obtained
through Diego Garcia is apparently a little ratty, we are
eager to get to our final orbit since the DSN is better
configured for us. Instruments appear to be healthy.
