    Abstract: A satellite system includes a satellite in an orbit that is configured to reduce a number of exclusion regions and improve the observation coverage of resident space objects (RSOs) positioned in near Earth orbits. The satellite system includes at least one satellite positioned in a sun synchronous orbit (SSO) with a noon/midnight nodal crossing. The altitude of the SSO is between 1000 and 2000 kilometers and the satellite includes at least one sensor arranged on the satellite that is configured for detection, tracking, and/or identification. Using the noon/midnight nodal crossing is advantageous in that three main exclusion regions, the sun, eclipse, and Earth exclusion regions, are combined into only two exclusion regions for improved performance of the satellite system in observing RSOs.
