NORAD numbers given but no TLE



… will we ever see keps ???


CP6 TLE swapped by NORAD


Colin, VK5HI: ... the CP6 keplerian data being issued for CP6 is definitely incorrect. I have been using the Day227 element set for Hawksat for the last week. Have not encountered any wild frequency excursions. Today I downloaded element sets for Days 233 & 234 and compared them against Day227_Hawksat, with a “simulator” program I have. The CP6 sets show up to 3 KHz deviation at TCA, whereas the Hawksat are just a few hundred Hertz.
I have just used the Day 234 Hawksat keplerian set on the most recent pass, with excellent tracking. The AOS & LOS also align well.
SpaceTrak gives an RCS of .774 for Hawksat and .0575 for CP6, so I cannot understand how they are getting them mixed up…

cp6_35004_23082009

cp6_35003_23082009

Colin, you gave me a good task for this evening, hihi. I tracked CP-6 with TLE OBJ 35004 ( this was the original CP6 TLE) at 1815 UTC.
For the second pass I used the TLE OBJ 35003 (the original HAWKSAT TLE) at 1905 UTC.
You can see the deviation in the first image and a nearly constant – and correct Doppler shift correction – in the second one.
I know it’s hard to determine this exactly because all my passes are low here I Germany. The first pass was 11 deg, the second one 19 deg elevation.

So I agree with you, Colin – fine job!

Alan, ZL2BX: Yes it has seemed obvious that something changed with the TLE’s. Before I
went away in June I had no particular problem but since coming back last week I have seen up to 5kHz offsets during the pass but using the “Hawksat”
TLE’s this reduced to a few Hz with about a 500 to 600Hz difference between Com A and Com B. All very interesting!


Columbia TLE candidate


At this stage NORAD #42702 seems to be the closest fit. LH, LJ and LK are still very close.

Decay



Low Earth orbiting satellites experience orbital decay and have physical lifetimes determined almost entirely by their interaction with the atmosphere. The drag force that such a satellite experiences is due to its interaction with the few air molecules that are present at these altitudes. The density of the atmosphere at LEO heights is controlled by solar X-ray flux and particle precipitation from the magnetosphere and so varies with the current space weather conditions.

Encounters



As a service to the satellite operator community, the Center for Space Standards & Innovation (CSSI) offers SOCRATES-Satellite Orbital Conjunction Reports Assessing Threatening Encounters in Space. This service provides regular information on pending conjunctions on orbit over the coming week.

Twice each day, CSSI runs a list of all satellite payloads on orbit against a list of all objects on orbit using the catalog of all unclassified NORAD two-line element sets (TLEs) releasable to the public to look for satellite conjunctions over the next seven days. Here you can find a list with amateur-radio related satellites.

CelesTrak SOCRATES, predicts the following Orbital Conjunction Threats
