WebApr 4, 2024 · Initial orbit determination (IOD) from line-of-sight (i.e., bearing) measurements is a classical problem in astrodynamics. Indeed, there are many well-established methods for performing the IOD task when given three line-of-sight observations at known times. Interestingly, and in contrast to these existing methods, concepts from algebraic … WebApr 5, 2024 · The orbit determination method uses the EKF algorithm. The state variance matrix and the observation variance matrix are diagonal matrix, position state variance is 1 × 10 −10, velocity state variance is 1 × 10 −11, measurement variance is 1.745 × 10 −5. The measuring frequency of the observation camera is 1 Hz, and filtering period is 1 s.
