SkyTerra-1, also known as MSV-1 (Mobile Satellite Ventures-1), is a large geostationary communications satellite designed to deliver mobile satellite services (MSS) across North America. It was built to support next-generation satellite-enabled voice, data, and broadband services for government, enterprise, transportation, and public-safety users.

Launched on 14 November 2010, SkyTerra-1 operates in geostationary orbit (GEO) and is one of the most powerful commercial communications satellites ever deployed at the time of launch. The satellite was constructed by Boeing Satellite Systems (BSS) based on the proven Boeing 702 platform, optimized for high-power L-band and ancillary spectrum operations.

A defining feature of SkyTerra-1 is its very large deployable L-band reflector antenna, approximately 22 meters in diameter, enabling strong signal coverage to handheld and mobile terminals across the continental United States, Canada, Mexico, and surrounding coastal regions. This capability supports reliable connectivity for land, maritime, and aeronautical users, even in remote or underserved areas.

SkyTerra-1 was originally developed for SkyTerra Communications, later becoming part of LightSquared and subsequently Ligado Networks. The satellite plays a key role in hybrid satellite-terrestrial network concepts, combining space-based coverage with complementary ground infrastructure.
