Regarding AlSat 1 and its APRS payload, I thought that 145.825 MHz was the accepted frequency for all APRS on satellites. So I'm curious how that qualifies as not coordinated if they're following established procedure?
Thanks in advance for any additional knowledge you can share,

All,
Doppler measurements show that AstroCast 0.2 is object 44083, 2019-018F. Downlink: 437.1729 MHz.
Doppler measurements show that AISTechSat 3 is object 44103, 2019-018AB. Downlink: 436.7302 MHz. Note that this frequency has NOT been coordinated with the IARU.
Doppler measurements show that the PS4 stage of PSLV C45, with the AIS, APRS and ARIS payloads attached, is object 44104, 2019-018AC. The APRS payload of AMSAT-India is called AISat 1 and has downlink frequency 145.825 MHz. Note that this frequency has NOT been coordinated with the IARU.
Doppler measurements show that the 6U Cubesat M6P is now about 50 s behind the PS4 stage. TLEs for M6P are not yet available. The downlink frequency of M6P is 437.265 MHz. Note that coordination of this frequency has been DECLINED by the IARU because there is no amateur radio involved in this mission.
