Orbital elements based on amateur observations

Database of amateur observations using radio

Primary source of unclassified orbital elements
2018 - Launches to Orbit and Beyond

Listed are launches, irrespective of outcome, that were irretrievably committed to flight towards orbit or intended to accelerate the payload to escape velocity. The following notes should help with understanding the launch lists.

Launch times are in UTC and are from the launching agency or estimated by 'walking back' along the ground track to the launch site. Most orbit data and decay information comes from SpaceTrack but it occasionally contains inconsistencies (eg - incorrect re-entry dates or early sets of elements allocated to the wrong object) that need to be corrected from other sources.

To fill the gaps where elements are not formally published, usually because they have a classification of "Secret", some orbits are based on amateur observations using visual and radio techniques. Such data is published near-daily by Mike McCants, and the source observations along with observers' derived orbits can often be found in the web-based Seesat-L discussion group. Occasionally, early orbit data are published by satellite owners. In extreme cases, orbits are estimated from public data.

Space-Track occasionally fails to allocate names to objects in its catalogue. The SATNOGS online database of radio observations sometimes provides pointers to which Catalogue Number belongs to a satellite being tracked by its contributors.

Apogee and perigee are measured against a spherical Earth situated at the focus of the orbital ellipse and with a radius of 6378.145 km. Shown is the Anomalistic Period, or time to complete one circuit of the ellipse. It is not the same as the time taken to complete one circuit of the Earth. Care should be exercised when comparing with other published orbits because they may have been derived using a different model.

Users can go straight to specific launches by pointing to the page URL followed by the three digit launch number, eg - https://www.OrbitalFocus/Diaries/Launches/Launches.php?year=2018#001

Life <1 day
Classified US Government payload. Purpose, mission outcome and orbit unknown. Appears to have re-entered the Earth's atmosphere on the day of launch, an event that is unlikely to have been intended. SpaceX reported that the launch vehicle completed its mission as planned. The launch azimuth suggested it was heading for an inclination of about 50°. Originally scheduled for launch 2017 Nov 17 from Kennedy SC but launch delayed (and launch pad switched) because of an issue with a Falcon 9 payload shroud on another mission.

Small satellite from the University of Surrey, England. Released two Cubesats for use in orbital debris removal experiments. 2019 Feb 8, a harpoon capture device was demonstrated by firing at target carried by an inflatable boom extended from the satellite body. RemoveDEBRIS was intended to extend a drag device to take itself out of orbit. It failed to deploy when commanded 2019 Mar 4 and the orbit decayed naturally.

43874
in space
Probably military in nature and maybe intended for signals intelligence gathering (SIGINT). Initially in co-orbit with TJS-3 payload 2 and was probably attached to it on arrival at their original GEO station. Commenced eastward drift 2019 May 20 to begin a stop-start journey around the geosynchronous belt. From 2019 Sep - Dec, it stopped alongside Shijian 13 (42662/2017-018A) at 111° east, then 2020 Feb - 2021 Aug it was co-located with Shijian 20 (44910/2019-097A) at 88° east before commencing a westward drift. 2021 Oct it settled near 59° east alongside 2018-110C from where it had originally departed, remaining there until 2022 Jul 5. Continued to follow GEO belt and made further stops 2022 Sep 13 at 88° east near USA 233 (38070/2012-003A)) and 2023 Feb 8 at 137°.5 east near USA 298 (45465/2020-022B).

in space
Probably military in nature and maybe intended for signals intelligence gathering (SIGINT). Placed at 59° east with a simultaneously-launched TJS that may have originally been attached to it. The latter departed station 2019 May 20. Stayed on station until 2021 December when it was raised to graveyard orbit. This satellite is listed by Space-Track as a rocket body named 'TJS-3 AKM', an abbreviation for 'apogee kick motor'.
