  1. AP30/30A Plans & Lists WorkshopSubmission of Appendix 4 information under Articles 4 and 5

  2. Data capture by the SpaceCap (version 5) software Notices under Articles 4 and 5 of Appendices 30 and 30A submit Appendix 4 data items SPS (Space Plans Systems) database • Contains the basic characteristics and reference situation of the assignments • (AP30/30A Plans, Lists and Article 4 networks, notified assignments under Article 5) • - Similar structure SNS (SRS_ALL) database, with some differences in usage of the tables and fields Starting SpaceCap: - open a SPS (Space Plans Systems) database - select the “Plan” button (on the top right toolbar) Note: “Open Plan for Inquiry only” option enables to access on read only

  3. Data organization in the SpaceCap software (1) Common data to all frequencies of a network (satellite name, orbital position…) ———————————————————————► Diagrams data (type (Paper, GXT, File), file name, description) Note: normally filled in through other data entry forms ——————————————————————— Strapping information for Region 2 ——————————————————————— Agreements reached Note: captured in the “Coordination” data entry form ———————————————————————► Antenna beam characteristics (satellite antenna gain, boresight…) ———————————————————————► Group of frequencies (common characteristics such as polarization type and service area…) ———————————————————————► Notice Notice Notice Attachments Strapping (Region 2) Coordination Beam 1 Beam 2 Beam 3 Group 1 Group 2 Group 3 Group 1 (3)

  4. Data organization in the SpaceCap software (2) Group 1 Group 2 Group 3 Group 1 (3) Emission characteristics of a specific group (frequencies, power and modulation characteristics) ————————————————————► Service area, test points and typical earth station antenna characteristics of a specific group ————————————————————► Specific earth station antenna characteristics of a certain group in the case of feeder-link only (if any) ————————————————————► Emission/ Frequencies Modulation characteristics Srv. Area/ Typ. Antenna Assoc Specific Earth Ant. (feeder-link only) Assoc Specific Earth Ant. (feeder-link only)

  5. AP4 data capture observation concerning items specificto Art 4 & 5 of AP30/30A (1)

  6. AP4 data capture observation concerning items specificto Art 4 & 5 of AP30/30A (2)

  7. AP4 data capture observation concerning items specificto Art 4 & 5 of AP30/30A (3)

  8. AP4 data capture observation concerning items specificto Art 4 & 5 of AP30/30A (4)

  9. AP4 data capture observation concerning items specificto Art 4 & 5 of AP30/30A (5) Strapping method Description Condition Example Downlink Beam channels Feeder-link Beam channels Beam level strapping Connecting one downlink beam to a feeder-link beam For each downlink group of frequencies, a feeder-link group with frequencies having the same downlink channel number shall exist and vice-versa. Beam: Bmdl Grp1: 1, 3, 5, 7 Grp2: 2, 4, 6, 8 Beam: Bmfl Grp3: 1, 3, 5, 7 Grp4: 2, 4, 6, 8 Group level strapping Connecting one downlink group of frequencies to a feeder-link group of frequencies The channel numbers of the downlink group shall be equal to those of the feeder-link group. Beam: Bmdl Grp1: 1, 3, 5, 7 Beam: Bmfl Grp3: 1, 3, 5, 7 Assignment level strapping Connecting one downlink frequency to a feeder-link frequency Any downlink channel could be connected to any feeder-link channels. Beam: Bmdl Grp1: 3 Beam: Bmfl Grp4: 6
