A Tracking, Telemetry and Control (TT amp C) station is used to support polar satellites during the launch phase and when in service in their nominal orbits.

When improved prediction confirms the conjunction within the avoidance manoeuvre box (5 kilometres along the orbit and 2 kilometres both radial and out of orbital plane), an assessment is made as to whether to execute the manoeuvre or not.

If an identified object is predicted to pass within the warning box near the orbiter (25 kilometres along the orbit and 5 kilometres both radial and out of orbital plane), the Space Surveillance Network is requested to make additional observations and use them to compute a more accurate orbit of that object.

The procedure is executed by the United States Eastern Test Range and provides clearance of 200 kilometres along the orbit and 50 kilometres both radial and out of orbital plane for manned vehicles.

The M Star system had 72 operational LEO satellites in 12 inclined orbital planes.

There are three general classes of orbit that may be suitable for small satellites the geostationary orbit (GSO), the highly elliptical orbit (HEO) and the low Earth orbit (LEO).

Basic orbital parameters Geostationary orbit

These are time in orbit, projected area, orbital altitude and orbital inclination.

Indeed, the peace must be comprehensive, covering all tracks.

The ground stations periodically adjust the orbital locations of these satellites.

2. The spacing between GEO and the graveyard orbit

Both constellations comprised four satellites equally spaced in each of eight orbital planes that were inclined at 55 degrees, and spaced 45 degrees apart at the equator.

The following ESA geostationary satellites have been re orbited OTS 2 (orbiting 318 km above GSO), GEOS 2 (260 km), Meteosat 2 (334 km), ECS 2 (335 km) and Olympus 1 (due to a failure, this satellite has been left at orbit 213 km below GSO).

And she was going along the tracks, and the tracks split.

It has a fairly substantial number of asteroids between the orbit of the Earth out through to the orbit of Jupiter.
