FREGAT DEB
This catalog entry represents debris associated with a Fregat upper stage rather than an operating satellite. Objects like this are an important part of the space-sustainability story because fragments can remain in orbit long after the mission that created them has ended.

Immediate discovery
Why this satellite matters
Debris tracking uses the same orbital mechanics as satellite tracking, but uncertainty matters more. Small changes in atmospheric drag and incomplete measurements can grow into larger prediction errors over time.

Mission
Mission and purpose
Objects in this category may be crewed stations, modules, cargo vehicles, or other spacecraft directly connected with human activity in orbit. The exact role depends on the individual object.

Real orbital values
The mathematics
The current two-line element set reports approximately 12.4455 revolutions per day. Dividing 1,440 minutes by that value gives an estimated orbital period of 115.7 minutes.

Launch and deployment
The orbital catalog lists the launch designator as 2011-037PF. A fully sourced launch story, launch vehicle, deployment sequence, historical weather, and documented delays have not yet been added to this page.
Orbit
LEO orbit explained
Low Earth orbit is the region closest to Earth used by most crewed spacecraft, many science missions, Earth-observation satellites, and large constellations. Objects move quickly and commonly complete an orbit in roughly 90 to 130 minutes.
LEO can provide detailed Earth views, lower communications delay, and easier access than higher orbits, but it covers less area per spacecraft and is more affected by atmospheric drag.

Questions to explore
- Why do low-orbiting stations circle Earth many times per day?
- How do crews receive power, supplies, and communications in orbit?
Evidence
Sources and data notes
Current identity and orbital elements come from CelesTrak’s public GP data. Calculated orbit values are derived from the current TLE and may change after catalog updates. Mission-history claims are added separately and require authoritative sources.
