Phil,
Here are some parameters from a set of 200 that I thought you might
be able to use to get a set of AMSAT standard keplerian elements for
UOSAT-B.
Launch. 17:57.00 UTC March 1, 1984
UOSAT-B deploy. Launch + 4300 seconds.
Following values are at the time of UOSAT-B deploy.
Rotation of line of Apsides, + is in the direction
of the orbit: -3.12357 deg/mean solar day
Ascending node right ascension (ECI system): 175.3923 deg
Eccentricity: .4139783 E-3
Apogee: 372.62 n.mi
Perigee: 369.46 n.mi
Inclination: 98.25967 deg
Nodal regression, east is positive: 1.00073 deg/mean solar day
True anomoly: 226.9766 deg
Argument of perigee: 174.16983
Instantaneous geocentric latitude: 40.629187
Instantaneous longitude, positive west: -29.650437
Period: 98.5 min
Time since perigee: 3726.775 sec (may be bogus, since 50 seconds
later, this value is 3549.826)
Let me know if there are any other values or info you need.
The figures I've got are for the second stage. The last time the second
stage and uosat-b are in similar orbits is launch +5453 seconds. At that
time, the lat. is 67.208371 and long. is 127.766825.
[The preceeding messages have been relayed from Harold Price, NK6K, who
is with the U of Surrey launch campaign team at Vandenburg Air Force
Base. I will be posting additional information on the launch of UoSAT-B
as it arrives. -Phil, KA9Q]
