  • Unmanned aircraft systems for bridge inspection : testing and developing end-to-end operational workflow

    Creator:
    Gillins, Matthew N.
    Abstract:
    Bridge inspections are vital for monitoring the health and serviceability of transportation infrastructure throughout the world. However, inspections can be logistically-challenging, expensive, and dangerous. For example, inspections may require climbing, as well as the use of scaffolding, ladders, rescue boats, bucket trucks, and/or under-bridge inspection vehicles. Small, multirotor unmanned aircraft...

  • Small Unmanned Aircraft Systems (UAS) for Engineering Inspections and Geospatial Mapping

    Creator:
    Javadnejad, Farid
    Abstract:
    Small unmanned aircraft systems (UAS) carrying consumer-grade nonmetric cameras are increasingly utilized to generate high-resolution 3D geospatial data. Low cost, ease of operation, widespread availability and low altitude maneuvering capabilities of UAS, as well as the rapid development of technology and methods, make UAS-based photogrammetry applicable to many civil engineering...

  • Investigation of Multi-constellation RTK GNSS Survey Productivity and Coordinate Accuracy

    Creator:
    Jamieson, Marian H.
    Abstract:
    This study evaluates the productivity and accuracy of surveys completed with single-base real-time kinematic (RTK) Global Navigation Satellite Systems (GNSS) using four different GNSS constellation combinations: (1) GPS-only, (2) GPS+GLONASS, (3) GPS+Galileo+BeiDou, and (4) GPS+GLONASS+Galileo+BeiDou. For this comparison, we set up a test site consisting of 20 stations ranging with...
