Real time positioning, visualisation and guidance of structure placement may be provided as an extension of monitoring solutions. Traditional survey sensors such as robotic total stations and GNSS systems may be augmented with accelerometers and inclinometers to enable full 3D position and attitude modelling in real time. Such a configuration allows an online visualisation and guidance tool in addition to providing an accurate record of a structure emplacement. Applications include bridge structure installation, mast section placement and oil platform module extensions.
