Keplarian elements are probably generated by Norad. Most stuff in orbit
is tracked by them occasionally. They maintain 'The Catalog' of most
observable stuff in orbit. Individual missions may be tracked by
assorted people interested in where the vehicles are. Additionally people
may transcribe one element set into other readable formats.
As for the actual tracking, its not that hard of concept. An initial
guess (like a propagated old element) is used to estimate where the
satellite should be at the time of an observation. Some sort of
measurement is made. This can be time of passage overhead, range and/or
range_rate from radar, or even satellite to satellite position/velocity
measurement. The estimated information is compared to the measured info
and an error measurement is generated. The error is used to modify the
estimated position. Through repeated measurements the estimated position
(hopefully) converges to the true position.
The keplarian elements are a more convenient representation of the
position, velocity,and time (state vector) of the satellite.
If you really want to know more say so. I've had several classes on the
subject.

hi, mitch wa4osr here in mobile, alabama usa... you need to subscribe to
The Radio Observer magazine published by Robert M. (Bob) Sickels,
7605 Deland Ave., Ft. Pierce, Florida 34951 USA. This magazine is
"...devoted to the radio astronomy amateur..." and is a very good
source of low cost electronic circuits, antennas and ideas for the
amateur radio astronomer. Bob has been credited with discovering
several astronomical radio sources. It is not a fancy magazine but
is a labor of love from a dedicated and talented amateur.

SB SAREX @ AMSAT $STS-58.019
SAREX Keps & Update for 10/25/93
The SAREX school groups have completed another round of outstanding
contacts the past few days. Today, the Nashua HS in Nashua, New Hampshire
had an outstanding horizon-to-horizon contact. A total of 12 questions
were answered by Astronaut Rick Searfoss who is from the "Granite State" of
New Hampshire. On Sunday the Eastern Heights JHS, in Elyria, Ohio, the
Ernest Elliot School in Munster, Indiana, and the Space Center Intermediate
School in Houston, Texas all had superb contacts with the crew on the Space
Shuttle Columbia. At the Space Center Intermediate School 19 students had
the opportunity to talk to astronaut Bill McArthur, KC5ACR. This contact
ties a SAREX record for the highest number of questions answered during a
direct contact.
The above successful contacts have cleared three school group backup
passes for possible general QSO opportunities. While we cannot fully
guarantee availability, there is a high probability that the STS-58 crew
will be ready and waiting to take general calls over the continental U.S.
on these passes. These opportunities include passes on orbit 145 at
MET 9 days 0 hours 6 minutes (10/27 at 14:59 UTC), orbit 178 at MET 11 days
1 hour 42 minutes (10/29 at 16:35 UTC) and orbit 192 at MET 11 days 22
hours and 29 minutes (10/30 at 13:22 UTC).
The following represents the official SAREX Keplerian element set for
10/25/93 as generated by Ron Parise, WA4SIR, of the Goddard Space Flight
Center:

NOTE - This element set is based on NORAD element set # 025.
The spacecraft has been propagated to the next ascending
node, and the orbit number has been adjusted to bring it
into agreement with the NASA numbering convention.

STS-58 Western R/S Times 10/26
Below are the rise and set times for STS-58 for selected US cities
over the next three days. This data was generated to help hams without
orbit programs to participate in the SAREX activities. Please note that
the times shown are UTC and NOT LOCAL TIME. This listing includes only
those passes with an elevation greater than 5 degrees. For information
regarding SAREX frequencies and operations procedures, check your
local PBBS, or bulletins from W1AW, W5RRR, W6VIO or WA3NAN.
Symbol key: rise = time that shuttle appears above horizon
tca = time of closest approach to observer
set = time that shuttle disappears below horizon
el = maximium elevation above horizon
geo = geometry: A = Ascending orbit, moving south to north
D = Descending orbit, moving north to south
E = passes east of observer
W = passes west of observer

They didn't hear it from me, but could have. On Sunday morning at ~8,
K?5AXA (I really did hear him, just can't remember the call) was "pinning"
the LCD meter on my IC2SRA using a 5/8 wave antenna on my car. I heard
him call CQ 3 or 4 times before working someone. I called him a few times
on 144.95 and 144.97. Are they still using the same uplink frequencies as
before? Do I remember them correctly (144.93, 144.95, 144.97)? Has anyone
ever worked the Shuttle using other than high power and directional
antennas?
