• Case: Two frequency groups are submitted with the same characteristics except for the input power.• One assignment with two power levels might lead to inefficiency of the Plan in terms of spectrum usage.• Different power levels per assignment has been considered and incorporated into the range of automatic

gain control of the associated feeder-link assignments (for downlink assignments) and into the power control specified under Appendix 4 data item C.8.i (for the feeder-link assignments).

• Example:

Group IDEmission characteristics

(bandwidth, polarization, antenna characteristics, etc.)

Reception characteristics (bandwidth, polarization,

antenna characteristics, etc.)

polar contours)

25

Part B and Notification shall be submitted to the Bureau within 8 years since the date of receipt of Part A, in accordance with § 4.1.3 and § 4.2.6 of Appendices 30 and 30A

Part B and Notification may be submitted at the same time to the Bureau: If the Notification information (Appendix 4 and GIMS data) is the same as the Part B

information, just the Part B information is needed with an indication that this data will be also used for the Notification. In this case, the date of brining into use of the satellite network shall be also submitted.

In case Part B is already submitted and published (assignments are included in the List for Regions 1 and 3 or in the Plan for Region 2), the notification may be submitted later:

If the Notification information (Appendix 4 and GIMS data) is the same as the Part B information, there is no need to submit the Notification databases, it is enough to indicate that the Notification data is the same as the Part B data in a correspondence to the Bureau. In this case, the date of brining into use of the satellite network shall be also submitted.
