SkyTerra is now called Ligado. Ligado wants to build a 5G terrestrial satellite network. They tried building a 4G network when they were called LightSquared but interference issues with GPS stopped them.

"Among the issues raised was whether political contributors and investors received favorable treatment by President Barack Obama's administration. Before he became president, Senator Obama had invested between $50,000 and $90,000 in SkyTerra, which later became LightSquared.[46][47] An Air Force General claimed in a closed congressional hearing that he had received political pressure to soften his testimony regarding the negative effects of LightSquared technology."

The present company Ligado has a long list of previous incarnations.

1988 American Mobile Satellite Corporation became Motient Corporation > merged with TMI Communications to become > Mobile Satellite Ventures > changed names to SkyTerra Communications in 2008 then LightSquared now Ligado

I have a vague memory (about 10 years ago) of hearing a story about dead engineers related to this technology.
