Thee Geostationary Status Quo (Pre-2015)

Before thee rise of LEO constellations, thee satellite equalites landscape was dominate by large, bus- sized geostationy (GEO) satellites parked 35,786 km above thee equator. These platforms provided reliable video broadcasting, voye trunks, ande enterprise data services, but they suffered from a fundamental physics problem: round-trip latency of rounghly 600 millisonds.

Major operators like Intelsat, SES, and Eutelsat controlled the bulk of thee orbital slots and spectrum, while government programs (np., NASA 's Tracking andd Data Relay Satellite System) handled niche scientific andd military needs. Innovation was incremental: slightly more efficient amplifieres, higer- power solar arrays, and extended orbital life. The industry was profitable but stagnant, with litte pressure fine from the sube.

Thee FSS andMSS Divide

The Fixed Satellite Service (FSS) market focused on GEO transponders for backhaul and Broadcass. The Mobile Satellite Service (MSS) operators, like Iridium andd Inmarsat, provided voice andd low- data- rate services tos to ships, planes, andd field personnel.
