POLICY. roscopes and a single GPS receiver—ideal for applications where there's dynamic movement, such as a moving UAS, boat or automobile. The system takes measurements from the GPS, gyroscopes and accelerometers and, with help from the Kalman filter algorithm, derives po- sition, velocity and attitude. The challenge for Fagerman's UAS-based mobile LiDAR solution is what happens in low dynamic or static conditions, such as when a UAS is hovering. That's where VectorNav's sub- sequent release of the VN-300 Dual-Antenna GPS-Aided Inertial Navigation System (INS) came into play. At a lightweight 30 grams and a size not much larger than a postage stamp, the VN-300 builds on the VN-200 architecture by incorporating two GNSS receivers. Two GPS antennas connected to the VN-300 spaced a certain distance apart and carrier phase inter- ferometry enable the VN-300 to estimate the heading solely from GPS signal measurements when the vehicle is stationary. The VN-300 combination was exactly right for Fagerman's ScanLook Revolution. Besides the VN-300 INS, the low-cost LiDAR map- ping product incorporates a LiDAR scanner, onboard data logging and WiFi interface for remote control and provides sub-meter preci- sion—an accuracy that is suitable for a range of applications where relative position measure- ment, rather than absolute centimeter-level position measurement, is a factor. For exam- ple, powerline encroachment is an important application because a utility company doesn't need to have a high level of accuracy to make an assessment, Fagerman added. The company believes the law enforcement market may be a good fit for this technology "WITH [SCANLOOK REVOLUTION], it's one time down the street and surveyors get all curb and gutter measurements, all the mailboxes, all the fire hydrants." Jeff Fagerman, CEO of LiDAR USA HÉLICÉO CREATED THE DRONEBOX TECHNOLOGY in order to meet the demands of professionals for multiple applications. This "Plug & Play" device is adaptable across Hélicéo's entire range of products, allowing you to perform precision measurement with multiple vehicles and sensors while reducing your investment.
