Orbital elements based on amateur observations

Satellite observers' discussion group

Database of amateur observations using radio

Primary source of unclassified orbital elements
2021 - 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=2021#001

TJS 6 (Communication Technology Test Satellite 6)
2021-010A
47613
in space
Described as a technology test satellite, TJS 6 is probably military in nature and possibly with a missile early warning rôle. Manoeuvred to geosynchronous drift orbit 2021 Feb 5 or Feb 6 and settled at its geosynchronous location after a small number of days. It joined TJS 6 (44978/2020-002A) and they remained together until Apr 16, approaching to within 10 km of each other.TJS 5 then departed for a new location.

Supplies to ISS. Docked with Pirs module Jan 17 at 06:27 UTC under manual control by the ISS crew after a course deviation during the planned automatic approach. Undocked 2021 Jul 26 a few seconds before 10:56 UTC with ISS Pirs module attached in order to clear the Zvezda lower docking port for the arrival of the Nauka module. Retro-fire for 17.5 minutes beginning at 14:01 UTC led to destructive re-entry at 14:42 UTC with any surviving fragments hitting the surface of the southern Pacific Ocean at 14:51 UTC.

Chinese government or military satellite described as being for 'space environment studies and related technology experiments'. A short thruster firing Mar 12 at about 10:25 UTC raised perigee slightly rather than move the satellite into Geosynchronous drift orbit. Smaller firings followed over the next few days. Starting 2011 Mar 21, more than one year after launch, a series of firings by the onboard thruster produced an inclined geosynchronous orbit.

Undocked 2021 Sep 18 at 02:25 UTC and re-docked with the forward-facing port of Tianhe about four hours later, clearing the rear port for the upcoming Tianzhou 3. 2022 Jan 5 at 22:12 UTC, Tianzhou 2 was undocked using Tianhe's robotic arm. After rotating 20° away from the station's axis and back, it was re-docked at 22:59 UTC. 2022 Jan 7 at about 22:00 UTC, Tianzhou 2 undocked from Tianhe and backed away. At 23:55 UTC it was re-docked at the same, forward, port under manual remote control by the CSS crew. Undocked for final time 2022 March 27 at 07:59 UTC. Retro-fire Mar 31 at around 10:00 UTC, whilst passing over central China. led to destructive re-entry above the southern Pacific Ocean at 10:40 UTC with any surviving debris hitting the ocean surface a few minutes later.

Three days after launch, started to reduce its orbit height rapidly, losing about 20 km per day under the influence of a constant force - probably a continuously-acting thruster. The manoeuvre was completed Sep 14.

Launch initially unacknowledged by China for more than one day and was initially declared a failure. However, 2021 Oct 14 at around 14:00 UTC and while at apogee, a thruster firing was used to raise perigee indicating that the satellite was under some degree of control. It had. the effect of counteracting the orbit decay being experienced due to air drag at 170 km. 2022 Mar 30, six months after launch, thruster firings increased the inclination to 63° and the satellite settled into a 'standard' Molniya-type HEO.
