§ 25.283 End-of-life disposal.
(a) Geostationary orbit space stations. Unless otherwise explicitly
specified in an authorization, a space station authorized to operate in
the geostationary satellite orbit under this part shall be relocated,
at the end of its useful life, barring catastrophic failure of
satellite components, to an orbit with a perigee with an altitude of no
36,021 km + (1000·CR·A/m)
where CR is the solar radiation pressure coefficient of the spacecraft,
and A/m is the Area to mass ratio, in square meters per kilogram, of
(b) A space station authorized to operate in the geostationary
satellite orbit under this part may operate using its authorized
tracking, telemetry and control frequencies, and outside of its
assigned orbital location, for the purpose of removing the satellite
from the geostationary satellite orbit at the end of its useful life,
provided that the conditions of paragraph (a) of this section are met,
and on the condition that the space station's tracking, telemetry and
control transmissions are planned so as to avoid electrical
interference to other space stations, and coordinated with any
potentially affected satellite networks.
(c) All space stations. Upon completion of any relocation authorized by
paragraph (b) of this section, or any relocation at end-of-life
specified in an authorization, or upon a spacecraft otherwise
completing its authorized mission, a space station licensee shall
ensure, unless prevented by technical failures beyond its control, that
stored energy sources on board the satellite are discharged, by venting
excess propellant, discharging batteries, relieving pressure vessels,
or other appropriate measures.
(d) The minimum perigee requirement of paragraph (a) of this section
shall not apply to space stations launched prior to March 18, 2002.
