Osiris Rex Opnav
This is called Optical Navigation OpNav, and it is a technique that has been used on many missions, including OSIRIS-REx during its time at Bennu. However, using OpNav for Celestial Navigation CelNav is not something that has been used as the primary method for navigating a spaceraft before.
Strategic planning and development of OpNav ConOps Narrative Each OSIRIS-REx mission phase is unique in terms of trajectory geometries, spacecraft constraints, and science and navigation objectives. Strategic planning for a mission phase is kicked off 3 months before the phase is slated to . 4
navigation OpNav, using images taken by the OSIRIS-REx camera suite OCAMS Rizk et al. 2018 and the touch-and-go camera system TAGCAMS Bos et al. 2018, will be the primary means of navigation for proximity operations. The team uses OpNav when the

Optical navigation OpNavwas critical to the success of OSIRIS-REx's mission to collect a sample from asteroid Bennu. Landmark-based OpNav was particularly important for achieving the highest precision mission requirements. This paper assesses the performance of the landmark OpNav after the transition from centroid-based OpNav at the end of
Optical navigation OpNav is a critical subsystem of the OSIRIS-REx asteroid sample return mission, which operated in the vicinity of near-Earth asteroid 101955 Bennu from August 2018 through April 2021. A substantial amount of mission resources across multiple subsystems and institutions is required to ensure that the OpNav data are successfully acquired.
This paper presents results of the OSIRIS-REx OpNav team's routine trending of the NavCam1 imager pointing with respect to the spacecraft attitude, including analysis of thermal deviations the NavCam boresight correlated with sun-on-deck geometry as well as operation of high-energy instrument payloads. These analyses facilitated the

The specific challenges of OSIRIS-REx required nimble OpNav planning, robust data management, and quick, automated analyses and data-product delivery capabilities. In addition to the two primary image processing tools, centroid-based and landmark-based OpNav, a host of support and planning tools and procedures were developed.
For the New Horizons, OSIRIS-REx, and Lucy missions, KXIMP OpNav processing is performed once images are downlinked to Earth. Going forward, however, more of this processing will be performed using onboard systems running autonomous OpNav software. Our team is actively working on these efforts. For NASA's LunaH-Map spacecraft, for example, we
