Hi all,

I finally had some time to complete and write up my analysis of the Malligyong-1
incremental orbit raises from earlier this month:

https://sattrackcam.blogspot.com/2024/06/the-north-korean-satellite-malligyong-1.html

Combined with my earlier analysis of the orbit raises in February, a clear
pattern is emerging.

I expect the next series of incremental orbit raises to initiate on either
Monday 9, Monday 16 or Monday 23 September, 2024. They will raise the average
orbit back to ~503 km.

All the early June orbit raising increments (one per day over 5 days, from June
3 to June 7) happend during late (22-23h local time) evening passes over
Pyongyang, as they did in February.

The sun-synchronous orbit has a repeating ground track after 76.007 revolutions,
i.e. each 5 days.

- Marco
