The Commission adopted a Notice of Proposed Rulemaking (NPRM) to streamline its procedures for reviewing satellite license applications. Before 2003, the Commission used processing rounds to review those applications. In a processing round, when an application is filed, the International Bureau (Bureau) issued a Public Notice establishing a cutoff date for other mutually exclusive satellite applications, and then considered all those applications together. In cases where sufficient spectrum to accommodate all the applications was not available, the Bureau directed the applicants to negotiate a mutually agreeable solution. Those negotiations took a long time, and delayed provision of satellite services to the public. The NPRM invited comment on two alternatives for expediting the satellite application process. One alternative was to replace the processing round procedure with a "first-come, first-served" procedure that would allow the Bureau to issue a satellite license to the first party filing a complete, acceptable application. The other alternative was to streamline the processing round procedure by adopting one or more of the following proposals: (1) place a time limit on negotiations; (2) establish criteria to select among competing applicants; (3) divide the available spectrum evenly among the applicants. In the First Report and Order in this proceeding, the Commission determined that different procedures were better-suited for different kinds of satellite applications. For most geostationary orbit (GSO) satellite applications, the Commission adopted a first-come, first-served approach. For most non-geostationary orbit (NGSO) satellite applications, the Commission adopted a procedure in which the available spectrum is divided evenly among the qualified applicants. The Commission also adopted measures to discourage applicants from filing speculative applications, including a bond requirement, payable if a licensee misses a milestone. The bond amounts originally were $5 million for each GSO satellite, and $7.5 million for each NGSO satellite system. These were interim amounts. Concurrently with the First Report and Order, the Commission adopted an FNPRM to determine whether to revise the bond amounts on a long-term basis. In the Second Report and Order, the Commission adopted a streamlined procedure for certain kinds of satellite license modification requests. In the Third Report and Order, the Commission adopted a standardized application form for satellite licenses, and adopted a mandatory electronic filing requirement for certain satellite applications. In the Fourth Report and Order, the Commission revised the bond amounts based on the record developed in response to FNPRM. The bond amounts are now $3 million for each GSO satellite, and $5 million for each NGSO satellite system.
