Modular Aerial Sensing System (MASS)
The MASS is a portable package of high-resolution instrumentation built specifically for airborne remote sensing applications. Instrumentation includes an airborne topographic lidar integrated with video, infrared, and hyperspectral imaging systems. The system is coupled to a highly accurate GPS-aided inertial measurement unit (GPS IMU), permitting airborne measurements of the sea surface displacement, temperature, and kinematics. These data are used to measure ocean waves, currents, Stokes drift, sea surface height (SSH), ocean transport and dispersion, and biological activity. Hydrological and terrestrial applications include measurements of snow cover, sand erosion, and the built environment. The MASS has over 500 hours of accumulated flight time over the course of over 20 different campaigns and has been installed on Cessna 206, Partenavia P-68, and DHC-6 Twin Otter fixed wing aircrafts as well as on a Bell 206 helicopter.
