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]
