Updated October 5, 2023
As of October 5, 2023 at 15:00 ET, Luch (Olymp) 2 [Norad ID 55841] has significantly slowed and appears to be parking near ~3.2° East, within ~60 km of another GEO spacecraft.
Slingshot’s object profiling algorithms identified multiple parking maneuvers. The Slingshot Global Sensor Network has verified Luch (Olymp) 2’s location. We are continuing to track this developing situation.
A Brief History
When Luch (Olymp) 2 [Norad ID 55841] launched in March 2023, it was unclear how closely its behavior would mirror its predecessor, Luch (Olymp) [Norad ID 40258], a well-known interloper among geosynchronous satellites. Since Luch (Olymp)'s launch in September 2014, it has approached and loitered near other satellites in geosynchronous orbit, sparking international concern.
In recent days, Slingshot’s machine learning-based object profiling engine has identified multiple maneuvers by the new Luch (Olymp) 2 satellite that are highly reminiscent of the behavior exhibited by its predecessor – suggesting that perhaps Luch (Olymp) 2 is now picking up where Luch (Olymp) left off. This behavior has resulted in numerous close approaches with other satellites in geosynchronous orbit.

Machine Learning-Based Object Profiling and Alerts
Slingshot’s machine learning-based object profiling engine processes data from multiple sources to continuously and autonomously monitor the behavior of all GEO spacecraft – providing near real-time automated alerts of anomalous behavior by spacecraft in geosynchronous orbit, and generating valuable insights for space operators and nearby satellite operators.
Shortly after Luch (Olymp) 2 initiated its maneuver on September 26, 2023, Slingshot’s maneuver detection algorithms determined that Luch (Olymp) 2 had begun drifting westward at a rate of ~1°/day, before slowing its drift to ~.3°/day on October 2, 2023, near ~3° East, where it appears it will visit another “neighborhood” of GEO spacecraft.
Optical Tracking & Data Validation
After detecting the Luch (Olymp) 2 maneuver, the Slingshot Global Sensor Network validated the behavior identified by Slingshot’s algorithms and provided additional insights regarding the nature of the activity, with two projected close approaches of ~16 km and ~61 km taking place near ~2.9° East and ~3.1° East, respectively.
The above image shows the Slingshot Global Sensor Network’s optical tracking of Luch (Olymp) 2 as it drifted past a number of GEO satellites on its journey from ~9° East to ~3° East.
Where to Next?
In addition to providing analytics on past movements, Slingshot’s object profiling engine offers live alerts and analytics on activities in the space environment, flagging anomalous movement and behavior as it occurs, as well as predicting future events and encounters.
Slingshot's algorithms predict future events by leveraging past satellite behavior and analyses of satellite "neighborhoods" to project the most probable future events – and have predicted where Luch (Olymp) 2 is most likely to complete its current drift.
Slingshot’s object profiling engine and the Slingshot Global Sensor Network will continue to keep a watchful eye on Luch (Olymp) 2 and all other satellites in GEO.
