Computer model of high-precision navigation of a small satellite constellation for remote Earth sensing tasks

Abstract

One of the key tasks in the formation of the small satellite constellation is to ensure its stable configuration in time. The specific of this problem lies in the fact that the task must be solved in real time with sufficiently high accuracy with significant restrictions on the power consumption of onboard satellite systems. The paper briefly discusses one possible approach of secondary signal processing and solving the navigation and ballistic tasks, which involves the joint use of code, phase measurement methods, integer phase ambiguity resolution, and inter-satellite measurements.
