There looks to be at least one sat using the amateur band on this launch: https://www.spacekidzindia.in/sdsat-pass/
I’ve not found much information on the official page, and then this popped up on twitter this morning:
… so it looks like its using LoRa, on 435.50 MHz. Doesn’t appear to be coordinated. I don’t know yet if it’s transmitting anything else.
UPDATE: Looks like it will have FSK and CW beacons - https://twitter.com/SpaceKidzIndia/status/1365423016776187907
GHRCESat at 437.500 Mhz (uncoordinated) and at 436.000 Mhz (uncoordinated)
JITSat at 437.500 Mhz (uncoordinated) and at 436.000 Mhz (uncoordinated)
SSIETSat at 437.500 Mhz (uncoordinated) and at 436.000 Mhz (uncoordinated)
So in practice we have 4 satellites with frequencies filed as radio amateur satellite service by WRC in India, flown by ISRO and uncoordinated with IARU.
All 4 will be monitored in our Network, flagged as misproper frequency use in DB and reported. If anyone has any contacts with those teams, please reach out.
It seems that OBJECT B(47700) is part of the rocket, so it is not the right OBJECT to follow.
After some observations, it seems that TLE from tinygs fit better SDSAT, which by the way is alive. For example check bellow the image generated with ikhnos:
The wide signal is from INNOSAT-2 but the other one fits the TLE set and it has to be SDSAT. For using this TLE set I have propagated it with strf tools and here is the result:
We are going to use these TLE set for the other 3 satellites from this launch. As OBJECT B it separates too fast from the orbit that the TLE above describe, I’m going to remove (and re-schedule) any scheduled observation after 2021-03-01 00:00. If you had scheduled any of these satellites far in the future, please re-schedule them.
@michel unfortunately it is not. It is ION-MK01 a commercial, non IARU coordinated deployer that transmits at 437.150MHz.
With the TLE set used for this observation you should expect something near the center (not more than ± 15KHz) with a small curve. For example check https://network.satnogs.org/observations/3709485/ from SDSAT (after 300s), this is how much in the center should be and the how much curved.
SDSAT is changed to follow OBJECT X(47721) as it fits better with the current observations. Still to early for identification as we may miss some TLE sets and 17/19 are stil in TBA(TO BE ASSIGNED) from spacetrack, which means we can expect changes, swaps etc…
Nothing received from UNITYSATs. SDSAT is still received and it seems to follow OBJECT W(47721) (renamed from OBJECT X to W from spacetrack). Nanoconnect-2 looks like it is alive and follows OBJECT C(47701), however the signal seems to have different baudrate, so I’ve added one transmitter in DB with baudrate closer to the one that was observed and re-scheduled some of the observations.
EDIT: We are far from identification as still many OBJECTS are still TBA.
SDSAT is received multiple times, it seems that it drifts between 2.7-4.2 KHz. Still OBJECT W(47721) fits well.
Nanoconnect-2 is still received… it definitely transmits in a lower baudrate than 115200, it looks like 9600. By accident(now is fixed) I’ve set it to follow OBJECT E(47703), but still from the receptions we have it fits better to OBJECT C(47701).
The last two are pretty separated from the rest of the group, so I estimate that soon we will be able to identify them.
