Information for "orbit-compare-01.pdf" This PDF is a plot of three satellites, for a 12 hour duration starting at Midnight, on December 16, UTC. The three satellites are from orbital elements obtained from NORAD (updated Dec 15). They are: Orbview (Microsat) TRMM SAC-A (Hitchhiker Payload Ejected from STS-88 on Dec 13) SAC-A should be very similar to UASAT's orbit. Its very near 51.6 degrees inclination, and an average altitude just under 400 km. From preliminary estimations, its orbit lifetime is between 1 and 1.8 years (depend on guesses you us for size and mass). 12/15/98 Chris Lewicki
