Oil and Gas • Offshore oil and gas production is constantly being refined through the support efforts of a great diversity of specialized vessels, barges, Floating Production Storage Offloading (FPSO) structures and moving rigs. • Therefore, the availability of reliable and precise positioning is an absolute necessity for guaranteeing efficient and effective operations. • The growing need to move into deeper waters of 1000 meters and more makes DGPS a key technique for positioning vessels in these demanding conditions. • Most Remotely Operated Vehicles (ROV) and construction support operations, seabed surveys, pipe laying and rig move applications generally require 5-meter accuracy. Examples: GNSS for semi-automatic guidance of machines to uncover power lines Example from construction industry together with energy industry in repairing power lines As the exact position of a pipeline can be documented, it can be found semi-automatically and maintenance and repair work will be more efficient and safer GNSS for time signal for safe energy switchgear and energy management Power plants and power suppliers need exact timing information for safe energy switchgear and energy calculation METIS First Master Training & Seminar, Ifrane (Morocco), 15-16.03.2007

  24. Differential GPS (DGPS) (1/2) • Differential correction techniques are used to enhance the quality of location data gathered using global positioning system (GPS) receivers. Differential correction can be applied in real-time directly in the field or when postprocessing data in the office. Although both methods are based on the same underlying principles, each accesses different data sources and achieves different levels of accuracy. Combining both methods provides flexibility during data collection and improves data integrity. • The underlying premise of differential GPS (DGPS) requires that a GPS receiver, known as the base station, be set up on a precisely known location. The base station receiver calculates its position based on satellite signals and compares this location to the known location. The difference is applied to the GPS data recorded by the roving GPS receiver. • The corrected information can be applied to data from the roving receiver in real time in the field using radio signals or through postprocessing after data capture using special processing software.
