Beidou Satellites Misclassification - Bert Hubert's writings
2 days ago
- The author is deeply involved in GNSS monitoring and uses automated orbit matching via TLEs and the sgp4 library.
- Four Chinese BeiDou satellites (C21/C22 and C25/C26) are misidentified due to swapped tracking codes after paired launches.
- Official BeiDou designations indicate C21 as MEO03 and C22 as MEO04, but US Space Control Squadron data shows different matches.
- The misclassification seems to be a simple reversal (e.g., M11 and M12 swapped), which is easy to correct.
