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.

Jan 3, 2022 · 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.

Dec 29, 2021 · 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 the Orbital A phase.

OpNav utilizes five OSIRIS-REx imagers during different mission phases: PolyCam (0.8° FOV), MapCam (4° FOV), and SamCam (20.8° FOV) are part of the OCAMS suite and NavCam1 and NavCam2 (33°x44° FOV) make up part of the TAGCAMS suite. Table 1 shows the OpNav imaging plan by mission phase.

The navigation team uses these “OpNav” (short for optical navigation) images to monitor the spacecraft’s close orbit around the asteroid. These two OpNav images of Bennu’s southern hemisphere, which each have an exposure time of about 1.4 milliseconds, were captured Jan. 17 from a distance of about one mile (1.6 km).

Abstract—The Origins, Spectral Interpretation, Resource Identification, and Security–Regolith Explorer (OSIRIS-REx) spacecraft arrived at the near-Earth asteroid (101955) Bennu in December 2018 and executed a science observation campaign to …
