BCCSAT-1 is an educational multi-spectral Cubesat 1U developed by the cooperation between Bangkok Christian College and the King’s Mongkut university of technology north Bangkok. http://bccsat.bcc.ac.th/
Schedule When our cubesat is completely finished it will be launched into space in March 20,2021 06.07 AM UTC at Russia with the Soyuz-2.1 rocket by UNISAT-7 GAUSS SRL to the low earth orbit at 575 km. http://en.roscosmos.ru/21973/ and https://www.roscosmos.ru/30285/

BCCSAT-1 is a technology demonstration satellite in Thailand. High school students in Bangkok Cristian College in collaboration with King Mongkut’s University of Technology (KMUTNB) and the Radio Amateur Society of Thailand (RAST) https://www.youtube.com/watch?v=zEcg5q7ZBw0 are building the satellite.
The project aims to build capacity on systems engineering, space education, and radio communication technology to students. During the project, students will learn about communication technology through amateur radio activities. It also encourages other interested people to receive the satellite signal.
The main missions of BCCSAT-1 include: (1) testing in-house developed satellite transceiver and antenna in orbit (2) experiment of Slow-Scan Digital Video (SSDV) transmission from the satellite (3) take pictures of Earth by cameras onboard satellite
BCCSAT-1 communication subsystem is an in-house developed transceiver and antennas. It has the capability to transmit GMSK modulation signal at 9.6 kbps, FSK for SSDV at 1.2 kbps and receive AFSK signal at 1.2 kbps. The transceiver will send its parameter such as RSSI and temperature to the ground station.
BCCSAT-1 will carry four cameras onboard the satellite and aim to capture images of the Earth in different wavelengths: red, green, blue, NIR, and Red Edge band.
We hope to process the images acquired for the Normalized Difference Vegetation Index (NDVI) and widely used in Science education. The images will be widely distributed among amateur radio community via the experiment of SSDV transmission system and GMSK packets downlink. Moreover, BCCSAT-1 will be able to transmit pre-stored images chosen by high school students.
BCCSAT-1 will provide the multi spectral images by having the total of 5 cameras on board; Red, Green, Blue, NIR, and Red Edge bands. The images we get from these cameras will be used to process for the Normalized difference vegetation index (NDVI), that will significantly provides huge advantage on analyzing the terrain of the country.

Hi Tanan,
Can you please point us to the specifications for your 9k6 and 1k2 telemetry downlinks? Usage of the amateur radio band requires that satellite operators release all their telemetry formats. This allows interested amateurs to be able to have a go at decoding telemetry, and allows projects like SatNOGS to help collect telemetry using the huge networks of volunteer ground-stations.
In particular I would be very interested to decode the SSDV data.
Also, it looks like this frequency was not coordinated with the IARU - or at least it's not showing up on the IARU coordination list ( http://www.amsatuk.me.uk/iaru/finished.php ).

Good day Tanan,
Thanks for sharing the information on the modes being used and the location to additional information.
But regarding your remark that Astroberry is responsible for the IARU coordination and not RAST, there we don't agree and I am very surprised that a Radio Amateur Society is using that argument, you of all should know the function of this coordination and should make sure that it is done.
Regards,

If Astoberry was responsible for coordination, then they have failed at their job, because BCCSAT is not listed on the IARU coordination page. Hence, BCCSAT is uncoordinated and should not be using amateur radio spectrum... Every coordination listing has a responsible amateur radio operator listed - who is that responsible operator in this case?
Finally, while the extra information you have provided is useful (e.g. the documentation of the CW telemetry), it is incomplete. A closed-source binary does not constitute complete documentation of your downlink telemetry. - Table 7.1 shows a list of parameters, but it does not define the data-types, or conversions for each of them. This is necessary to decode the telemetry. - Your software decodes the SSDV imagery, but there is no information in your documentation on how the imagery is encapsulated and transmitted. Is this purely SSDV packets (e.g. encoded using https://github.com/fsphil/ssdv ) encapsulated in AX.25 frames?
