Technical Examination

Technical examination of submitted notices

Once the databases submitted are complete

• The BR performs a technical examination to determine the potential interference of the incoming network to the existing services from other administrations

• As a result, the BR publishes the identification of potentially affected administrations/networks in a Special Section, which is considered as a request for coordination for these administrations

My Administration does not have any satellite network in operation or planned, should I continue reading this presentation?

YES! Radio Regulations reserve a portion of Orbit-Spectrum for every ITU state member in form of Plan assigments/allotments for future use

Plan assigments/allotments are taken into consideration for interference calculation

AP30/30A frequency bands are also allocated to Terrestrial Services and could be interfered

Exercise: Detect identification with SpaceQry

In this exercise, you will play the role of administration “TUN”

FIRST PART – Detect identification with SpaceQry

1. Open SpaceQry

2. Select a database (Microsoft access)1. [USB drive]:\Space Workshop\Day 4\AP30_30A_30B_Basic\5-AP30_30A_Examination_results\Exercise\SPS_ALL_IFIC2874.mdb

2. Click “Start”

3. Go to tab “BR IFIC DVD”

4. Activate flag “Show only the latest BR IFIC info” and Select “Planned bands networks interfering with my Admin.”

5. Type, the name of administration “TUN” and click on “Search”

6. For each interfering network, open the list of identifications

7. Identify, according to the coordination provision (coord_prov), which kind of potential interference would be received

SECOND PART – Detect identification with Special Section

1. Open Special Section AP30/E/795 annexed to BR IFIC 2874 related to NSS-BSS G2 22W network1. [USB drive]:\Space Workshop\Day 4\AP30_30A_30B_Basic\5-AP30_30A_Examination_results\Exercise\2874-AP30-AP30e0795.pdf

2. Search your administration in the pdf (Edit -> Find, search for code “TUN”)

3. Identify, according to the coordination provision (coord_prov), which kind of potential interference would be received

THIRD PART – Read MSPACE results published in BR IFIC

1. Open SPS_REPORTS, click on File -> Open, and connect to the MSPACE results database1. [USB drive]:\Space Workshop\Day 4\AP30_30A_30B_Basic\5-AP30_30A_Examination_results\Exercise\117552024_NSS-BSS G2 22W_mspace_results.mdb

2. Select Plan_id = 00DN and click on “OK”

3. Open all “Compressed”, “Graphical” and “Reference Situation” reports (select and click “Show Report”)

4. In the Reference situation Report, type “TUN” in “Administrations”, activate flag “Only affected beams / channels to be shown” and click on “Retrieve Ref.Sit / Margin”

5. Identify which channels and test-points have been identified as affected (distinguish between EPM, PFD or EPM/PFD affected)
