Hi Jan,
Thanks! Due to policy considerations, unfortunately it would not be appropriate for us to release the preliminary TLE directly before deployment.
But I can share some low-precision information that should be enough to build a rough orbit for preparation:
Orbit: approximately 530 × 545 km
Inclination: approximately 97.5°
Separation is expected at around 11:35 local time (UTC+8).
At the time of separation, the spacecraft should be roughly*near the southernmost part of Vietnam.
Passes predicted from this information may be off by several minutes, but hopefully it is enough to build an approximate orbit for initial preparation.
You can use the ASRTU-1 decoder for Harbin MicroSat as well.
