Mapping from manned aircraft has taken advantage of Direct Georeferencing for several years. Whether using Hyperspectral, LiDAR, SAR or Photogrammetry, knowledge of the precise position and orientation of an imaging sensor means that the location of image elements on the ground can be accurately computed without extensive networks of ground control points. In small unmanned systems, constraints of size, weight, power and cost have presented challenges to effective Direct Georeferencing. Applanix' Direct Mapping Solutions for Unmanned Aerial Vehicles (DMS-UAV) address those challenges.
The Trimble APX-15 UAV is a GNSS-Inertial OEM solution designed to reduce the cost and improve the efficiency of mapping from small Unmanned Aerial Vehicles. Comprised of a small single OEM board containing a precision GNSS receiver and inertial sensor components plus post-mission Differential GNSS-Inertial office software, the Applanix APX-15 UAV eliminates the need to survey extensive Ground Control Points (GCPs), and reduces the amount of sidelap to be flown, thus increasing the area flown per mission. It is ideal for frame cameras, multi and hyperspectral scanners and LiDAR.
For higher altitude UAV applications the Trimble AP20 provides greater orientation accuracy with the use of a custom MEM's based IMU.
