title = "Multi-arc filtering during the navigation campaign of the osiris-rex mission",
abstract = "The Navigation Campaign of the OSIRIS-REx mission consisted of three phases: Approach, Preliminary Survey and Orbital A. These phases were designed to optimize the initial characterization of Bennu{\textquoteright}s mass, shape and spin state to support a safe orbit insertion and a quick transition to landmark-based optical navigation tracking. The standard orbit determination filtering techniques used to navigate the spacecraft were unable to fit data from these three phases simultaneously due to numerical issues associated with the nonlinear dynamics and the long arc length. Consequently, a multi-arc filtering algorithm was implemented in order to combine the information from each of these arcs. Multi-arc solutions for Bennu{\textquoteright}s spin state and gravity field are presented here.",

note = "Funding Information: We are grateful to the entire OSIRIS-REx Team for making the encounter with Bennu possible. Specifically, we would like to thank the Altimetry Working Group for producing such remarkably precise shape models so early on in the mission, and the OpNav team for generating navigation observables of a quality that surpassed all expectations and for all of their insights into navigation performance.
