Spectrum and Satellites orbits management
The ITU Radiocommunication Sector ITU Radiocommunication Sector plays a vital role in the global management of the radio-frequency spectrum and satellite orbits, managing the detailed coordination and recording procedures for space systems and earth stations.
The Second Session of the Conference Preparatory Meeting 2023 (CPM23-2) prepared a consolidated report supporting the work of World Radiocommunication Conference 2023 (WRC-23) and based on:
- Presentation, discussion, rationalization, and updating of material from responsible groups, addressing WRC-23 agenda items, while taking into account contributions from ITU Member States and Radiocommunication Sector Members relating to the regulatory, technical, operational and procedural matters to be considered by the conference.
- Inclusion, to the extent practicable, of reconciled differences in approaches as contained in the source material or – in the case where all efforts to reconcile differences have been exhausted – alternative approaches with justifications were included.
Results of the processing of space notices and other related activities
In 2022, were processed: 1’208 Coordination and notification requests; 393 Requests for broadcasting-satellite and associated feeder links Plans; and 226 Requests for fixed-satellite service Plan.
Terrestrial notices
In 2022: 63’893 Notices were recorded in the MIFR/Plans; 11’311 High-frequency broadcasting requirements were processed; 25’530/ 407 Monitoring observations concerning the monitoring programme at 2 850-28 000 kHz/ and 406-406.1 MHz were processed; and 1’007 Reports of harmful interference were received.
Improvement of ITU-R software
The Radiocommunication Bureau (BR) continues to produce software applications and databases to best facilitate the use of ITU-R outputs by ITU membership. In 2022, BR continued to update the software that enables users to query and analyse the Table of Frequency Allocations (TFA) in Article 5 of the Radio Regulation, as well as other texts including WRC resolutions, referenced ITU-R Recommendations and rules of procedure. This application extracts regional and country-specific regulations for the presentation of regional or national tables of frequency allocations.
Progress in terrestrial services
- Development of the software and tools for processing coordination requests (RR No. 9.21) and HAPS notifications (validation, examination, and publication tools)Migration of the TerRaSys database from Ingres to SQL Server.
- Development and enhancement of the eTerrestrial web platform, integrating eMIFR, ePropagation, eValidation tools for all terrestrial services and specific eFXM and eBroadcasting tools (eQuery, ePub, eTools and MyAdmin).
- Enhancement of the online tools for GE84[1] (GE84 compatibility and optimization tools) to include the consideration of terrain elevation in the field strength calculations.
- Re-engineering and modernization of High Frequency Broadcasting software dealing with the application of Article 12 of the RR.
- Modernization of the Maritime Service Publications (List V, List IV and Maritime Manual) to improve the user experience. The project includes the creation of the sales platform desktop and mobile applications to retrieve information and anti-counterfeit solutions.
- Development of a new online platform HITS – Harmful Interference to Terrestrial Services – for treatment of the reports of harmful interference and infringements.
- Re-engineering and integration of eValidation to WISFAT 2.0.
Progress in fulfilling the BR Space Information Systems roadmap (RAG-19, 2012)
- Rewrite legacy software for technical examination: PFD, Mspace.
- Design and development of the BR Space Information System (BR SIS): BRSIS-Capture to replace SpaceCap, migrate SNS database on Ingres to SQL Server, migrate SRS MDB to SQLite, review SNTrack, review SNS Online and merge with SNL Online.
Achievements resulting from activities for space applications
- Implementation of Resolution 907 (Rev.WRC-15): Use of modern electronic means of communication for satellite network-related administrative correspondence.
- Implementation of Resolution 908 (Rev.WRC-15): Electronic submission of satellite network filings.
- Release of a tool to assist administrations in communicating to the Bureau, at notification stage, the coordination status with respect to affected administrations.
- Migration of the BRIFIC (Space services) from a DVD format to an online mechanism.
- Implementation of instructs the Director of the Radiocommunication Bureau 2) and 6) of Resolution 186 (Rev.Bucharest 2022) and the publication of CR/495 published on 26 January 2023 about Online Information of Space Radio Monitoring Facilities.
