This legislation amends the Secure and Trusted Communications Networks Act of 2019, establishing new prohibitions on satellite communications licensing. It prevents the Federal Communications Commission from granting licenses or United States market access for geostationary or nongeostationary orbit satellite systems, or authorizations for earth stations, if such control would be held by entities that produce or provide covered communications equipment or services , or their affiliates. The bill defines various types of earth stations, including individually licensed earth stations , blanket-licensed earth stations , and gateway stations , all of which fall under these new restrictions. These prohibitions apply to any license, market access, or authorization granted on or after the bill's enactment date, aiming to bolster national security by preventing certain entities from controlling critical space-based communication infrastructure. The Federal Communications Commission is mandated to issue comprehensive rules to implement these provisions within one year of the Act's enactment.
