摘要: A GNSS ultra-tight coupling (UTC) receiver architecture applicable to space borne orbit platforms is described. in accordance with this retains the rotational motion sensors typically found an inertial measurement unit (IMU) of a conventional UTC receiver, but replaces IMU accelerometer precise orbital dynamics models predict translational platform center gravity (CG). Drag and radiation pressure may be modeled as well. The various can implemented software. are retained for compensation antenna lever arm effect due rotation.
