Various World Radiocommunication Conferences have revised Appendices 30 and 30A to the Radio Regulations.
The Bureau is using the revised Appendices 30 and 30A as adopted at WRC-12 in its examination of the regulatory and technical aspects of submissions to modify the Plans/Lists. It is also publishing the related Special Sections, that contain the filed satellite network characteristics and coordination requirements.
Pursuant to Footnote 32 to Article 9A of Appendix 30A
, the Bureau has computed power control values for all assignments in the Regions 1 and 3 feeder-link Plan as adopted by WRC-2000. For assignments in the Regions 1 and 3 feeder-link List, the Bureau has calculated power control values only for those with a request to use power control. For more information on the implementation of power control, please see Circular Letter CR/356
. Calculated power control values in tabular format:
This information also exist in the "pwr_ctrl" table of the SPS database (BR IFIC 2762 and later).
The latest reference situations resulting from these modifications to the constantly evolving Plans/Lists are contained in the zipped SPS Version 7 database below.
Space Plans Systems (SPS) Version 7 Database
NOTE 1 - The technical characteristics and reference situation (EPM) for the Appendix 30/30A Plans & Lists and for pending Article 4 networks are provided in the Space Plans Systems (SPS) Version 7 database (MS Access 2000 format).
In order to properly view the SPS database, SpaceCap
(v7.0.0 or later) or SpacePub
(v7.0.0 or later) software is required. SPS (v22.214.171.124 or later) is required to perform an MSPACE analysis on the networks contained in this database. Note that this database does not yet contain data for Appendix 30B
networks (The Appendix 30B database is here
NOTE 2 - Reference EPM values provided in the Regions 1 & 3 Plan and List files were calculated taking into account the interfering effect between Plan and List assignments and a 9° orbital separation limit. The user should set the MSPACEg options accordingly.
- The following software needs to be installed to perform an analysis on the various Space Plans.
The Bureau has produced video presentations to assist administrations in using the SPS/MSPACEg software application:
shows how to run MSPACEg for Appendix 30
Region 1 & 3 downlink assignments.
shows how to run MSPACEg for Appendix 30A
Region 1 & 3 feeder-link assignments.
shows how to run MSPACEg for Appendices 30
Region 2 assignments.
