Subj: Changes to AMSAT-NA TLE Distribution for March 22, 2024
Path: IW8PGT<IZ3LSV<I0OJJ<GB7CIP<VK2RZ<PE1RRR<KA1VSC<WG3K
Sent: 240324/0045Z 2469@WG3K.#SMD.MD.USA.NOAM LinBPQ6.0.24
Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. Elements in
the TLE bulletin files are updated daily. TLE bulletin files are updated to
add or remove satellites as necessary Thursday evenings around 2300 UTC, or
more frequently if new high interest satellites are launched. More
information may be found at
https://www.amsat.org/keplerian-elements-resources/
The following satellite has been added to this week's AMSAT-NA TLE
Distribution:
SONATE-2 - NORAD Cat ID 59112 Downlinks on 437.025 MHz, 145.825 MHz,
145.840 MHz and 145.880 MHz have been coordinated by the IARU. Thanks to
Nico Janssen, PA0DLO, for the identification.
The following satellite has been removed from this week's AMSAT-NA TLE
distribution:
BeliefSat-0 NORAD Cat ID 58695 End of mission.
This mission was interesting as BeliefSat-0 is not a free flying satellite.
Instead it is a "hosted payload" on a larger platform, in this case the
spent upper stage of an Indian launch vehicle. The stage was modified such
that it included solar panels and attitude control, so BeliefSat 0 and
other payloads were designed to simply bolt on and plug in to a regulated
power source. See
https://www.isro.gov.in/POEM-3_Mission_achieves_Payload_objectives.html for
details.
While BeliefSat-0 and its host POEM-3 remain in orbit for now, it appears
that BeliefSat-0 has been shut down as there have not been any successful
observations of it in SatNogs for several weeks. POEM-3 will reenter within
the next few weeks "leaving zero debris in space" according to the Indian
Space Resource Organization.
[ANS thanks Joe Fitzgerald, KM1P, AMSAT Orbital Elements Manager for the
above information.]
