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. TLE bulletin
files are updated 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 satellites have been removed from this week's AMSAT TLE
distribution:
MESAT1 remains on this distribution. No signals have been detected from any
other amateur spacecraft launched as part of NASA's ELaNa 43 mission.
ELaNa 43 OBJECT A NORAD Cat ID 60203 No amateur signal detected
ELaNa 43 OBJECT B NORAD Cat ID 60204 No amateur signal detected
ELaNa 43 OBJECT C NORAD Cat ID 60205 No amateur signal detected
ELaNa 43 OBJECT D NORAD Cat ID 60206 No amateur signal detected
ELaNa 43 OBJECT E NORAD Cat ID 60207 No amateur signal detected
ELaNa 43 OBJECT F NORAD Cat ID 60208 No amateur signal detected
ELaNa 43 OBJECT H NORAD Cat ID 60210 No amateur signal detected
Zhou Enlai NORAD Cat ID 43156 Decayed from orbit on or about 17 July 2024
TEVEL-5 NORAD Cat ID 50998 Decayed from orbit on or about 18 July 2024
The following satellites have been added to this week's AMSAT TLE
distribution:
GRBBeta NORAD Cat ID 60236 IARU coordinated downlinks on 145.935 MHz,
436.785 MHz and 2405.000 MHz
ROBUSTA-3A NORAD Cat ID 60241 IARU coordinated 9k6 GMSK with AX.25 downlink
on 436.750 MHz
Thanks to Nico PA0DLO for identifying the two new spacecraft.
