Add Tianmu-1 satellite

[amilan17]

Initial request

Apply WMO codes for Tianmu-1 Meteorological Sounding Constellation: Satellite Instrument | Satellite Identifier in this website. https://codes.ecmwf.int/odb/satelliteidentifier/

The Aerospace Tianmu Satellite Science and Technology Co., Ltd company operates the Tianmu-1 constellation, which has 23 satellites in operation, producing approximately 30,000 radio occultation profiles daily. We are engaged in the ROMEX data agreement and share occultation data with ROMEX/EUMETSAT/ROMSAF, indicating our active collaboration with relevant authorities. We would like to apply our satellite identifiers for the convenience of ROMEX further data assessment and operational application.

• Jeff suggests one entry for CCT5 for the cluster of satellites, IF needed, the satellite sub-identifier (001016) can be used to identify a particular satellite in the cluster
• @SimonElliottEUM please bring this request to CGMS as needed

Since this is a LEO satellite, I'm suggesting code figure 540 in CCT C-5 for this new satellite cluster as noted above, and pending agreement from CGMS.

waiting for confirmation from CGMS... @jbathegit will update branch

[SimonElliottEUM]

@amilan17 @jbathegit I can confirm that there were no points raised by the CGMS Task Group on Satellite Data and Codes. So we can move forward with this proposal.

The branch is now updated
