(a) The recipient of an initial license for a GSO space station, other than a DBS or SDARS space station, granted on or after August 27, 2003, must launch the space station, position it in its assigned orbital location, and operate it in accordance with the station authorization no later than five years after the grant of the license, unless a different schedule is established by Title 47, Chapter I, or the Commission.
(b) The recipient of an initial license for an NGSO satellite system, other than a DBS or SDARS satellite system, granted on or after September 11, 2003, must launch the space stations, place them in the assigned orbits, and operate them in accordance with the station authorization no later than six years after the grant of the license, unless a different schedule is established by Title 47, Chapter I, or the Commission.

Compliance with a milestone requirement in paragraph (a) or (b) of this section may be demonstrated by certifying pursuant to § 25.121(d) that the space station(s) in question, has, or have, been launched and placed in the authorized orbital location or non-geostationary orbit(s) and that in-orbit operation of the space station or stations has been tested and found to be consistent with the terms of the authorization.
(g) Licensees of satellite systems that include both NGSO satellites and GSO satellites, other than DBS and SDARS satellite systems, must meet the requirement in paragraph (a) of this section with respect to the GSO satellite(s) and the requirement in paragraph (b) of this section with respect to the NGSO satellites.
(h) In cases where the Commission grants a satellite authorization in different stages, such as a license for a satellite system using feeder links or inter-satellite links, the earliest of the milestone schedules will be applied to the entire satellite system.
