Eliminating timing errors in spaceborne TDoA arrays using bidirectional optical time-transfer protocols.
Because electromagnetic waves travel at approximately 30 centimeters per nanosecond, an inter-satellite timing error of just 10 nanoseconds translates directly to a 3-meter measurement error on the ground. OrbitGeolocation uses bidirectional laser links to exchange optical time-transfer pulses, eliminating oscillator drift across orbital planes.
