Agenda-item type Technical

What's being studied — points to watch

Territorial exclusion

Whether a constellation can keep off one country's territory without adversely affecting service in the rest of the system's service area (Res. 14).

Technical enforceability

How exclusion would actually be achieved — Res. 14 notes terminals can carry geolocation and emission-cessation functions, alongside directional-antenna discipline.

Authorization vs global service

Balancing an administration's right to control use in its territory against fragmenting a globally-designed system.

Scope: FSS and MSS

The measures span both fixed- and mobile-satellite non-GSO user terminals in the Earth-to-space direction.
