Transitional measures for coordination between the mobile-satellite service (Earth-to-space) and the space research (passive) service in the band 1 668-1 668.4 MHz for a specific case
This resolution has been abrogated and is no longer in force. Version history is available below.
Preamble
The World Radiocommunication Conference (Geneva, 2007),
Considering
that WRC-03 made a global allocation to the mobile-satellite service (MSS) (Earth-to-space) in the band 1 668-1 675 MHz and a global allocation to the MSS (space-to-Earth) in the band 1 518-1 525 MHz;
that the band 1 660.5-1 668.4 MHz is allocated to the space research (passive) service;
that in the band 1 668-1 668.4 MHz, mobile earth stations and space research (passive) stations are subject to coordination under No. 9.11A;
that the relevant coordination threshold condition is given in Appendix 5;
that before WRC-07, Appendix 4 did not contain the relevant information for the request for coordination for passive services;
that before WRC-07, Appendix 4 contained all necessary data for request for coordination for MSS systems, and coordination information was submitted after WRC-03 for some MSS systems;
that there is one satellite system (SPECTR-R) in the space research (passive) service in the band 1 668-1 668.4 MHz for which relevant advance publication information has been communicated to the Bureau prior to WRC-07, and that it is necessary to provide some transitional measures for the treatment of this information by the Bureau,
Noting
that Report ITU-R M.2124 contains an assessment of sharing between the mobile-satellite service and space research (passive) service in the band 1 668-1 668.4 MHz;
that the satellite system SPECTR-R is associated with the RADIOASTRON project, which is an international project for a space very long baseline interferometry system,
Resolves
that, in the band 1 668-1 668.4 MHz, mobile-satellite service systems that exceed the relevant coordination threshold condition shall be coordinated with the SPECTR-R system operating in the space research service (passive), for which advance publication information was received by the Bureau on 7 December 2005, provided that the complete coordination information is received by the Bureau within the time-limit mentioned in No. 9.5D.
