GIBC (Graphical Interface for Batch Calculations) is a software package which provides the user with the ability to carry out calculations on satellite networks which allow determining the coordination requirements on satellite networks, relating to Power Flux Density (PFD) examination, Appendix 8 and Appendix 30B (Annexes 3 and 4), and on Earth stations relating to Appendix 7.

The PFD software examines satellite networks with respect to the PFD limits in Article 21 and in Appendices 30 and 30B of the Radio Regulations (2008 Edition of the Radio Regulations). Three types of PFD calculations can be performed: with respect to terrestrial services, with respect to other space services (Appendix 30, Annex 1, Sections 3 and 6 and Appendix 30, Annex 4) and in application of Annex 3 of Appendix 30B.

The Appendix 8 software determines the coordination requirements of a given satellite network through Appendix 8 calculations and the application of the coordination arc (see Appendix 5, Resolution 55 (WRC-2000) and circular letter CR/180). Since the number of potential cases where ?T/T > 6% is often very large, the program does not attempt to find the worst case for any administration with which coordination is required, but will present one case for which ?T/T > 6%.

Appendix 30B Annex 4 uses C/I as technical criteria to evaluate interference.

Appendix 7 software determines the coordination area around an Earth station.
