PART 25--SATELLITE COMMUNICATIONS--Table of Contents
 
                  Subpart B--Applications and Licenses
 
Sec. 25.141  Licensing provisions for the radiodetermination satellite service.

    (a) Space station application requirements. Each application for a 
space station license in the radiodetermination satellite service shall 
describe in detail the proposed radiodetermination satellite system, 
setting forth all pertinent technical and operational aspects of the 
system, including its capability for providing and controlling 
radiodetermination service on a geographic basis, and the technical, 
legal and financial qualifications of the applicant. In particular, each 
application shall include the information specified in Appendix B of 
Space Station Application Filing Procedures, 93 FCC 2d 1260, 1265 
(1983), except that in lieu of demonstrating compliance with item II.F 
(two degree spacing), applicants are required to demonstrate 
compatibility with licensed satellite systems in the same frequency 
band. Applicants must also file information demonstrating compliance 
with all requirements of this section, specifically including 
information demonstrating how the applicant has complied or plans to 
comply with the requirements of paragraph (f) of this section.
    (b) [Reserved]
    (c) User transceivers. Individual user transceivers will not be 
licensed. Service vendors may file blanket applications for transceiver 
units using FCC Form 312, Main Form and Schedule B, and specifying the 
number of units to be covered by the blanket license. Each application 
must demonstrate that transceiver operations will not cause interference 
to other users of the spectrum.
    (d) Permissible communications. Stations in this service are 
authorized to render radiodetermination service, and may not render 
other services except as ancillary to the radiodetermination service.
    (e) Frequency allocation policies. Each radiodetermination satellite 
service licensee will be assigned the entire allocated frequency bands 
on a non-exclusive basis. Coding techniques and power limits as set 
forth in paragraph (f) of this section and orbital spacing shall be 
employed to avoid harmful interference with other radiodetermination 
satellite service systems.
    (f) Radiodetermination satellite service. Licenses shall coordinate 
with radiodetermination satellite system licensees to avoid harmful 
interference to other radiodetermination satellite systems through:
    (1) Power flux density limits;
    (2) Use of pseudorandom-noise codes (for both the satellite-to-user 
link and for the user-to-satellite link); and
    (3) Random access, time division multiplex techniques.


Licensees shall coordinate with 1.6/2.4 GHz Mobile-Satellite Service 
system licensees to avoid interference to 1.6/2.4 GHz Mobile-Satellite 
Service systems.
    (g) License conditions. All authorizations in the radiodetermination 
satellite service shall be subject to the policies set forth in the 
Report and Order, including compliance with appendix D, and the Second 
Report and Order in General Docket Nos. 84-689 and 84-690 and to any 
policies and rules the Commission may adopt at the later date.
