ISSUE To address concerns raised with unauthorised earth stations while preserving regulatory certainty & flexibility

GSC Position Agenda Item 9.1.7

- Unauthorized Earth Stations -


AI 9.1 - Issue 9.1.7 Unauthorised earth stations

The GSC recognizes the concerns of administrations affected by unauthorized operation of earth stations terminals:

u  Re Issue 2a (Annex to Resolution 958 WRC-15): GSC supports Option 1 NO CHANGE to Radio Regulations (international regulatory measures already addressed appropriately with Art 18)

u  Additional Regulatory Measures will not resolve this problem of illegal transmissions

u  Re Issue 2b (Annex to Resolution 958 WRC-15): GSC supports ITU-R studies on best practices in training & monitoring and development of ITU reports/handbooks/capacity building to help administrations to prevent use of & locate unauthorized uplink earth terminals


Thankyou!
