Navigating the Cosmos: Spacecraft Tracking & Orbit Determination
Keeping Tabs on the Cosmos: The Art and Science of Spacecraft Tracking and Orbit Determination Ever wonder how we know where satellites are, or how we manage to send probes billions of kilometers across space? It all comes down to a fascinating field called spacecraft tracking and orbit determination (STOD). This isn't just about knowing the location of a spacecraft; it's a complex dance between physics, mathematics, and advanced technology that allows us to accurately predict and control where our celestial explorers go. The Eyes in the Sky: At its core, STOD relies on a global network of ground stations equipped with powerful antennas. These stations constantly listen for signals from spacecraft, like faint whispers carrying telemetry data and position...
