Abstract

Due to lack of spacecraft's global position and attitude information on small solar system bodies (SSSBs) like asteroids, only relative state measurements are available for navigation. Therefore, relative navigation with respect to a local reference frame is the basis for in-situ autonomous exploration on the asteroids. The relative navigation changes a local reference frame during the flight, which guarantees local accuracy of state estimation and mapping. We present the relative navigation framework using surfel grid map-based scan-to-map matching for localization and mapping on asteroid surface. We also propose a terrain-based path planning that makes use of inherent terrain surface properties of surfel grid maps. A thorough validation of our navigation approach and comparison to a global flash LiDAR-based navigation in different flight scenarios and in both MIL (model-in-the-loop) and real-time PIL (processor-in-the-loop) tests show the viability of this novel navigation framework.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Real and simulated LiDAR data has proven efficient and robust data for neural network training in many applications, such as obstacle detection, path planning, and TRN even in the case of uncooperative operations.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
