LIDAR

The Light Detection and Ranging Instrument (LIDAR) on Hayabusa uses the time-of-flight measurement of a laser pulse reflected from the surface of asteroid 25143 Itokawa to determine the surface topography. LIDAR used a 1064 nm yttrium-aluminum-garnet-Nd (YAG-Nd) laser. Beamwidth was 0.04 x 0.097 degrees, giving a footprint at 7 km altitude was about 5 x 12 meters. From 10 September to 25 November 2005 4,107,104 shots were fired and 1,665,548 returns were detected.

The HAYABUSA spacecraft included a LIght Detection and Ranging  (LIDAR) altimeter. 
            The primary objective of LIDAR was to establish  the range between the HAYABUSA spacecraft and the asteroid Itokawa  
            for navigation purposes during the surveying and collection phases  of the mission.

The HAYABUSA spacecraft included a LIght
        Detection and Ranging  (LIDAR) altimeter. The primary objective of    
        LIDAR was to establish the range between the HAYABUSA spacecraft and  
        the asteroid Itokawa for navigation purposes during the surveying and 
        collection phases of the mission. It provided excellent estimates of  
        the location of the spacecraft relative to the asteroid.  The         
        Experiment Data Record (EDR) and Calibrated Data Record (CDR) from the
        Hayabusa LIDAR experiment are included in this data set. This updated 
        version of the HAYABUSA LIDAR data includes a new CDR where the       
        offsets between a high resolution shape model and the LIDAR data were 
        minimized by optimizing the spacecraft trajectory.
