This Fortnight in GEO

This Fortnight in GEO follows Luch/Olymp, TJS-3, Shiyan-12, SJ-20 and SJ-17 maneuvers during the second half of August 2022.

– Russia’s Luch/Olymp decreased altitude by 115km to slow its westward drift.

– TJS-3 continued drifting eastward toward its early-July position and was briefly in the vicinity of ELEKTRO-L3, a second-generation Russian geostationary meteorological satellite.

– SY-12(01) decreased altitude and reversed drift. It is now drifting eastward and was expected to be in the vicinity of Astra 1L, 1M and 1N communications satellites.

– SY-12(02) continued its eastward drift and was not in the vicinity of other satellites during this period.

– SJ-20 maintained its position at 33.5°E.

– SJ-17 continued its westward drift.

The graphics on page 8 show Luch/Olymp’s altitude change and slowing westward drift, SY-12(01)’s altitude decrease and drift reversal, and SY-12(01) passing near Astra 1L, 1M and 1N on 26 Aug 2022.
