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

Telematics solutions ITS (intelligent Transport Systems): combination of telecommunication and informatics (ICT – Information and Communication Technologies)

GNSS-based telematics combine use of GNSS for localisation. Main elements:

On-board device GNSS + communication (installed on private cars, fleet vehicles, trucks, trailers, coaches, etc.)

Communication backbone

Monitoring/Operative Centre

On-board device:Black-box GNSS/GSM-GPRS

Human machine Interface (optional)

Voice recognition (optional)

Integration with other devices (optional)

Road transport general architecture (1/2)


Road transport general architecture (2/2)On-board device sends PVT (Position, Velocity and Time data)

Monitoring/Operative Centre - Backend software platform that receives/displays data on digital maps, and manages for providing multiple applications:

Fleet Management & localisation

Tracing & Tracking

Dynamic real-time monitoring of transit on specific road stretches and access in areas

Speed control & law enforcement

Dynamic traffic monitoring & regulation

Navigation and Info-mobility (provision of

Location-sensitive information POI – Point

Of Interest, or real-time traffic data)

Personal Safety

Display and reporting of data from optional devices


Car equipped with on-board device: Black-box and/or HMI and/or other devices (RFID, digital tachograph, etc) – Panic button for emergency call

PSAP (Public Service Answering Point) for emergency assistance

Service Provider for added-value location info (traffic, POI, navigation-aid data)

Road safety


Road freightTruck or trailed equipped with on-board device: Black-box and/or HMI and/or other devices (RFID, digital tachograph, etc)

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.
