摘要： GNS signal correction system and method for calculating GNSS corrections, and complementary mobile and mobile position determination method based on these GNSS corrections. The methods employ satellite-single-differenced mixed code-and-phase system hardware delays in modelling carrier phase system observables. These system hardware delays are dynamically estimated by the signal correction system using a dynamic system state model. The estimated system hardware delays are transmitted to the mobile, which applies these delays to a dynamic mobile state model, in order to improve the accuracy and/or convergence time of mobile position estimations.

摘要： An underwater positioning system provides position information for a rover, moveable within a reference frame. The system may comprise: at least one beacon having a light source, located at a fixed position within the reference frame; an underwater imaging device, moveable with the rover in the reference frame to observe the light source from different viewpoints and determine direction data representing a direction or change in direction of the light source with respect to the imaging device; an orientation sensor, associated with the imaging device to determine an orientation of the imaging device with respect to the reference frame and generate orientation data; and a scaling element for providing scaling data representative of a distance between the imaging device and the light source. Various different beacons may be provided.In alternative system implementations, the locations of light source(s) and underwater imaging device are reversed between rover and beacon(s).

摘要： Mobile Offshore Drilling Units (MODUs) are more susceptible to meteorological conditions such as winds, currents and, most importantly, waves. These meteorological conditions generate a movement of the installation that will inevitably be transferred to some extent to the drilling pipe. A mobile offshore drilling unit can include a rooster box configured to move the rooster box along the height of a derrick to which it is attached. An injector configured to attach to an intervention frame of the rooster box, wherein the injector is configured to be releasably coupled to a conduit The injector configured to be positioned on-axis with the conduit in a first configuration and off-axis with the conduit in a second configuration.

摘要： Aspects of the subject technology relate to a method of correcting sensor position. The method comprises transmitting one or more first pulses of a first frequency range towards a first portion of a seabed and one or more second pulses of a second frequency range towards a second portion of the seabed, and receiving a first set and second set of backscattered data. The method further includes processing the first and second set of backscattered data to form a first and second set of image data and comparing the first set and second set of image data. The method further includes creating one or more error vectors between the first set and second set of image data, and updating the first set of backscattered data based on the one or more error vectors to produce an updated set of image data.

摘要： The invention relates to a method for monitoring remote infrastructure networks. The method comprises the steps of collecting spatially referenced data as physical of an area containing a remote infrastructure network, identifying the remote infrastructure network in the collected physical data, and building a parametrized model of the remote infrastructure network based on the physical data and on operational data, the parametrized model including a spatially referenced model of said remote infrastructure network. Further, the method comprises the steps of storing the parametrized model and updating the parametrized model by assigning updated physical data and/or operational data associated with the remote infrastructure network to at least one parameter of the parametrized model.

摘要： A method, system and computer program product for determining soil properties comprising a probe including at least a liquid injection port and a pressure transducer. The probe is pushed into a soil and one or more pumping tests are carried out, wherein during a pumping test infiltration liquid is pumped through the liquid injection port of the probe. By means of the pressure transducer a pressure response in the soil resulting from the injection of liquid through the liquid injection port is measured for each of the one or more pumping tests.

摘要： A system for measuring the attitude of an object in a fixed frame of reference from a moving frame of reference, comprising a first imaging device for producing image data for the object from a first direction, a second imaging device for producing image data for the object from a second direction having a component perpendicular to the first direction and an attitude sensing arrangement for determining an attitude of the first and second imaging devices with respect to the fixed frame of reference at the time the respective images are taken and for generating attitude data. An image processing system analyses and combines the respective image data and attitude data to determine the attitude of the object. The system is particularly useful for determining attitude of offshore piles during piling operations or for monitoring the departure angles of pipes and cables during laying thereof.
