Orbital elements based on amateur observations

Database of amateur observations using radio

Primary source of unclassified orbital elements
2023 - 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=2023#001

in space
Satellite carrier from a company called Launcher with six small satellites and four hosted payloads. Released from launch vehicle at L +01:26:11. Failed to establish orientation due to a problem with its onboard GPS. As a result it was unable to point its solar cells correctly and the internal batteries ran down so planned release of satellites was not possible.

Deployable payloads may include:
PROVES-Yearling (Pleiades Rapid Orbital Verification Experimental System) - 1U Cubesat from BroncoSpace al Calpoly, designed to allow users on the ground to experiment with satellite hardware and software - includes and imaging system.
Celestial - 1U Cubesat from Skyline as a demonstrator of its small satellite platform,
name unknown - 1U Cubesat from InnovaSpace - mission details awaited,
Sapling Sempervirens - 1U Cubesat from Stanford Student Space Initiative to demonstrate smart downlinking of images using a Google Coral camera and Google Coral Edge coprocessor,
name unknown - 1U Cubesat from Italian company NPC Spacemind,
name unknown - 1U Cubesat, unidentified owner.

Hosted payloads include:
CesiumAstro’s Nightingale - to demonstrate advanced phased array communication,

APStar 6E propulsion module

55447
in space
Intended to propel APStar 6E towards GEO. A fault prevented use of its main engine nozzle but, up to January 23, orbit raising used its low-thrust zozzles. Reportedly separated from APStar 6E January 23 at 13:31 UTC. It's first measured orbit indicates that its thrusters were fired some time after it departed from Apstar 6E.
