Systems, devices, methods, and computer-readable media for location determination of an orbiting device. A method can include receiving measurement data from a monitor device, the measurement data representative of a position of an orbiting space object with a mechanically moveable antenna, receiving, by processor circuitry, mission data indicating orientation of the antenna is changing from a first orientation to a second, different orientation by a specified time, determining, based on the mission data, an inter-signal correction (ISC), applying the determined ISC to the measurement data resulting in corrected measurement data, providing the corrected measurement data to a Kalman filter, and receiving, from the Kalman filter, a position estimate of the orbiting space object.
