Equipment
The ROSETTA initiative maintains and provides access to state of the art remote-sensing equipment to members of the Purdue community. This includes a high performance drone - DJI M600 model – equipped with an Applanix APX-15v3 Global Navigation Satellite System and Inertial Navigation System (GNSS/INS). The remote sensing capabilities are based on a Velopdyne VLP 32C LiDAR sensor, and a 42 megapixel Sony α7R III RGB camera. The VLP 32C LiDAR sensor is capable of generating 600k – 1.2 million data points per second with a measurement range of up to 200m. The data processing will provide positional accuracy to 5-7cm while flying at an altitude of 50m.
In addition, ROSETTA has a DJI Phantom 4 Pro quadcopter, equipped with a MicaSense Red Edge-M Multispectral sensor and VR flight goggles. Several iPad mini tablets are available with flight planning software for use aerial survey.
For geophysical remote sensing, ROSETTA hosts a dual array GEM Systems Overhauser magnetic gradiometer with onboard GPS. The magnetometer has an available aluminum cart for hands-free data collection.
For high-precision terrestrial positioning, we also maintain a TopCon GNSS mapping instrument.
