(b) Manoeuvre to an orbit for which atmospheric drag or gravitational perturbations will remove the object from orbit within 25 years

Atmospheric drag, distribution of ballistic coefficients and orbit eccentricity are taken into account in the orbit propagation.

aerospace object as involving a different degree of regulation from entry into airspace from outer space orbit and subsequent return to that orbit? 5

With regard to aerospace objects performing Earth orbit flights with flight paths passing through the airspace of another State, it is worth while examining the possibility of codifying in treaty form whatever norm is agreed upon for the peaceful (innocent) passage through the airspace of such States when the object enters orbit and when it returns from orbit.

(g) Ballistic coefficient a measure of the aerodynamic and area to mass characteristics of the object that will influence the orbital lifetime of an object until its entry into the upper atmosphere

Unidentified object is still orbiting.

INTELSAT satellite procurement documentation specifies designs which minimize outgassing and debris generation during transfer orbit deployments and in orbit operations.

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).

For that purpose, mainly three modes of operations were developed first a tracking mode of operation to measure selected objects in low Earth orbit, in geosynchronous orbit and in geostationary transfer orbit.

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.

Sweden participates in the meteorology programmes of ESA and Eumetsat, such as the programmes for development of the geostationary satellites Meteosat Second Generation (MSG) and the polar satellites Metop.

38. The following ESA geostationary satellites have been reorbited so far OTS 2 (orbiting at 318 kilometres above GSO), GEOS 2 (260 kilometres), Meteosat 2 (334 kilometres), ECS 2 (335 kilometres) and Olympus 1 (because of a failure, this satellite has been left in an orbit 213 kilometres below GSO).

However, for objects in high Earth orbit (HEO), such as those in geosynchronous orbit, observations can often be continued during the entire night.

In particular, in addition to the information listed with respect to orbital parameters, further information could be required on the planned flight path of the aerospace object through the airspace above States apos territories.

Whereas the collision risk between an orbiting object and a meteoroid is essentially independent of altitude, the probability of collision between orbital objects is strongly related to altitude, in general being an order of magnitude higher in LEO than in GEO.

(e) Deorbiting at end of LEO and GTO mission this includes both lowering the orbit to reduce the satellite lifetime (e.g. to less than 25 years) and immediate re entry.

To make further progress we really need to look at the orbits of stars that are much further away.

Models have predicted that the orbital debris environment could exceed the meteoroid environment in certain regions of low Earth orbit.

The minimum diameter of observable objects was about 10 centimetres for LEO and 1 metre for geostationary satellite orbit (GSO).

From these data the physical properties are derived like size, shape, dimensions, intrinsic motion, mass, orbit, and orbital lifetime.

These studies have demonstrated that there are significant selection effects where objects in eccentric orbits are less likely to be detected than those in circular orbits.

The following characteristics of orbiting objects are recorded

More than 8,500 catalogued objects are in Earth orbit.
