Data capture by the SpaceCap software for networks submitted under Articles 4 and 5 of Appendices 30 and 30A
The “Plan” subsystem of the SpaceCap software application was developed to capture the data items required to be submitted in notices under Articles 4 and 5 of Appendices 30 and 30A (AP30/30A). These data items were incorporated in Annex 2A of Appendix 4 at WRC-2000, as amended in the Annex to Corrigendum 1 to Circular Letter CR/158 of 15 March 2002.
The above-mentioned data items were further reviewed and incorporated in Annex 2 of Appendix 4 at WRC-03. The Bureau upgraded the SNS/SPS database structure (version 5) and the SpaceCap software (version 5) to comply with the revised Appendix 4 (WRC-03). WRC-07 further reviewed Appendix 4. The Bureau has upgraded the SNS/SPS database structure (version 7) and the SpaceCap software (version 7) to comply with the revised Appendix 4 (WRC-12).
The basic characteristics and reference situation of the assignments of the AP30/30A Plans, the Lists and Article 4 networks are recorded in the SPS (Space Plans Systems) database. Its structure is similar to the SNS (SRS_ALL) database, which contains non-planned space service networks, with some differences in usage of the tables and fields of the SNS database.
Currently, the Space Query and Extract System software (SpaceQry) can be used to view and query most of the data contained in the SPS database. SpaceCap should be used to capture data and to import data from/export data to other databases. The Bureau is currently upgrading SpaceQry to provide full functionality for handling AP30/30A notices.
After opening a SPS (Space Plans Systems) database, select the “Plan” button on the toolbar on the top right of the screen in order to open the Plan selection list. If the option titled “Open Plan for Inquiry only” is enabled, access to the information will be read only.
The organisation of data in the SPS (Space Plans Systems) database and the SpaceCap software as well as a description of the principle data entry forms are illustrated in Annex 1. Observations that should be taken into account for capturing the corresponding data items are listed in Annex 2.

DN: 11.7 – 12.5 GHz, ­: 17.3 – 18.1 GHz (Region 1).

DN: 11.7 – 12.2 GHz, ­: 17.3 – 18.1 GHz (Region 3).
­UP:14.5-14.8 GHz (countries outside Europe).
For Regions 1 and 3 feeder-link networks, the user first should select either the 14GHz or 17GHz frequency band for a newly created “Group” of frequencies. The assigned frequencies can then be captured on the Emissions/Frequencies data entry form.
If the user enters first the channel number, the corresponding center frequency in the Plan will be set by SpaceCap that could be modified by the user. If the frequency is entered first, the corresponding channel is calculated using the following formula:
Channel = Integer((Frequency + Channel_Spacing / 2 – Plan_Frequency) / Channel_Spacing) + 1
Frequency: center frequency of the assignment (C.2.a.1);
Channel_Spacing: 19.18 MHz for Regions 1 and 3; 14.58 MHz for Region 2;
Plan_Frequency: The center frequency of channel 1 of the Plans as

Considering that WRC-2000 adopted a value of 600 K for 17 GHz feeder-link and 750 K for 14 GHz feeder-link Plan national assignments, the administrations of Regions 1 and 3 may wish to consider the use of a value of 600 K for 17 GHz assignments and 750 K for 14 GHz assignments.

In the case of analogue emission, the reference bandwidths for calculating the maximum power density are 4 kHz for the downlink and 14 GHz feeder-link and 1 MHz for the 17 GHz feeder-link.
For digital emissions, the maximum power density default value (assuming uniform distribution of the power over the necessary bandwidth) is calculated once the total power is entered using the following formula:

This issue should be clarified in the fax or email corresponding to the submission.
For describing the internal grouping of the assignments of the network, a MSPACE group code should be assigned to this item for each group of assignments on the “Group” from of SpaceCap. If this field is blank, it is understood that no MSPACE internal grouping is applicable to the assignments of the corresponding “Group”.
It is to be noted that multiple MSPACE grouping for a specific assignment is not possible. For instance if assignment A should be grouped with assignments B and C, these two assignments have also to be grouped since they shall have the same MSPACE group code of assignment A.
