The traditional paradigm of GEO (Geostationary) satellites—high latency and low bandwidth—is being replaced by LEO (Low Earth Orbit) constellations like Starlink. By placing thousands of satellites at altitudes of 340-550km, end-to-end latency targets of sub-30ms are now achievable. These constellations function as a dynamic orbital mesh, where traffic is routed through space via optical links before descending to a ground station gateway.
Inter-Satellite Laser Links (ISL) eliminate the dependency on local ground stations for every hop. Because light travels 47% faster in the vacuum of space than in fiber optic glass, space-based routes can provide a lower-latency path for long-distance data transmission (e.g., London to Sydney) than terrestrial subsea cables.
Standard TCP relies on a constant end-to-end connection, which is impossible in deep space where planets and moons frequently block line-of-sight. Delay Tolerant Networking (DTN) utilizes the 'Store-and-Forward' Bundle Protocol (BP). Instead of dropping data when a link goes down, nodes cache the data until the next window.
Modern satellite terminals no longer use moving mechanical dishes. User Terminals (Starlink 'Dishies') utilize thousands of individual antenna elements to electronically steer a beam toward a fast-moving satellite. This technology, combined with rapid handoff protocols (switching between satellites every few seconds), allows a stationary object on earth to maintain a gigabit-class connection while the satellite moves at over 17,000 miles per hour overhead.
"LEO satellites orbit so fast that the ground station must handle doppler-shift correction in real-time."
"High-frequency bands provide the bandwidth required for space-link, but are susceptible to 'Rain Fade' during heavy storms."
"The primary L7 equivalent in space, designed to cope with delays that exceed several minutes or even hours."
