Sec. 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 less than:
36,021 km + (1000 ·C[R ·]A/m)
where C[R] is the solar pressure radiation coefficient of the spacecraft,
and A/m is the Area to mass ratio, in square meters per kilogram, of the
spacecraft.
(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 all stored energy sources on
board the satellite are discharged, by venting excess propellant,
discharging batteries, relieving pressure vessels, and 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.
