Headwall Nano-Hyperspec Operation Manual page 14

AIRBORNE PACKAGE
Notice in the above figure that from left to right the word HEADWALL rotates from the twelve-o-clock position through
to the nine-o-clock position. Additionally, the orientation of the IMU to the front/back axis of the Nano varies. These
positional variations are what need to be accounted for in the Ortho-rectification step of the data cube analysis. The
factory configuration for the Nano/IMU configuration is #2 above. Contact Headwall Support if this configuration cannot
be used.
Attaching an IMU to the Nano requires that the three holes in the central part of the face plate be used. Do not attempt the
use screws longer other than the supplied M3 x 0.5 x 6mm. Using longer screws will damage the Nano.
Use the following steps to attach the IMU to the Nano.
a. Remove the IMU and supplied mounting screws from the package.
b. Remove the Nano from the package and place onto the workspace, with the lens facing forward and the ON/OFF
switch to the right of the lens. This is position 2 above. The mounting holes are circled in the following figure.
a. Place the IMU onto the top of the Nano. Orient the IMU according to the y axis being aligned with the platform's
body and the z axis facing upward.
b. Move the IMU so the clearance holes for the screws match the mounting holes on the Nano, Figure 1-3.
