Orbital elements based on amateur observations
Satellite observers' discussion group
| 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.
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 SpaceTrack but it often contains errors and inconsistencies (eg - incorrect re-entry dates) 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.
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. Care should be exercised when comparing with other published orbits because they may have been derived using a different model.

| 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. |

| Remote sensing satellite with 1m resolution, possibly for cartography. It's name means "high resolution" in English. It will operate as part of a system to combine data from satellites in orbit with data from sensors flown within the atmosphere by aircraft and operating lifetime is expected to be 5-8 years. |
