WebMar 8, 2008 · To achieve the desired 90 m (3σ) landing accuracy terrain relative navigation (TRN) is necessary. The Johns Hopkins University Applied Physics Laboratory (APL) is developing a TRN system using passive optical terrain sensing for lunar, asteroid and comet landing applications. WebTerrain correlation may be done for one measurement, or for a sequence of measurements. The position is shifted around an offset area around the current position estimate, and match statistics between the measurements and the depth data in the Digital Terrain Model (DTM) is calcu- lated in this area. polystatic duster https://boytekhali.com
