WRC 2019 Agenda Items for WP 7B

This agenda item relates to consideration of in-band power limits for earth stations operating in the mobile-satellite service, meteorological-satellite service and Earth exploration-satellite service in the frequency bands 401-403 MHz and 399.9-400.05 MHz, in accordance with Resolution 765 [COM6/7] (WRC-15).

This agenda item relates to consideration of possible upgrading of the secondary allocation to the meteorological-satellite service (space-to-Earth) to primary status and a possible primary allocation to the Earth exploration-satellite service (space-to-Earth) in the frequency band 460-470 MHz, in accordance with Resolution 766 [COM6/8] (WRC-15).

The ITU-R is invited to study:

1. sharing and compatibility studies of such an upgrade while protecting existing primary fixed and mobile services
2. determine the appropriate pfd limit that would protect these existing primary services any upgrade to these services.

This agenda item relates to study of the spectrum needs for telemetry, tracking and command in the space operation service for non-GSO satellites with short duration missions, to assess the suitability of existing allocations to the space operation service and, if necessary, to consider new allocations, in accordance with Resolution 659 [COM6/19] (WRC-15).

The Resolution notes that short duration missions typically extend for less than 3 years.

The AI includes:

1. study of the spectrum requirements for TT&C in the space operation service for short duration missions,
2. to assess the suitability of existing space operation service allocations below 1 GHz taking into account current use and
3. if existing allocations are insufficient, conduct sharing and compatibility studies including mitigation techniques to protect incumbent services, both in-band and in adjacent bands, in order to consider possible new allocations or an upgrade to an existing allocations to the space operation service within 150.05 - 174 MHz and 400.15 - 420 MHz.
