| Abstract: | This paper proposes a computation method for initial orbit determination and orbit improvement with ranging and range rate data at low angular measurement accuracy or unavailability of angular measurement data based on the(Unit-Vector-Method(UVM)) principle.Applications show that the method effectively increases orbit determination accuracy at low angular measurement accuracy and high ranging and range rate measurement accuracy. |
