Abstract: A moving platform INS range corrector (“MPIRC”) module and its method of operation for providing navigation and positioning information. The module comprises: means, such as a receiver, for receiving a first set of absolute navigational information from an external source (such as satellites in case of GNSS); an inertial sensor unit for generating a second set of navigational information at the module; and a transceiver, for receiving and/or transmitting signals and estimating distance measurement from a known position and receiving position coordinates. The navigational information is used by a processor programmed with a core algorithm, to produce a navigation solution (which comprises position, velocity and attitude). The system has the following attributes: the solution is produced seamlessly, even if one source of navigational information is temporarily out of service; the accuracy of the solution is assisted by use of distance and position coordinate measurement from a known position.

Abstract: A navigation module for providing a real-time INS/GNSS navigation solution for a moving object comprising a receiver for receiving absolute navigational information from an external source and an assembly of self-container sensors for generating navigational information. The module also contains a processor coupled to receive the output information from the receiver and sensor assembly, and integrate the output information in real-time to produce an overall navigation solution. The overall navigation solution will contain a main navigation solution task, and at least one other task, where the other task is used to enhance the overall navigation solution.

Abstract: A navigation module and method for providing an INS/GNSS navigation solution for a moving platform is provided, comprising a receiver for receiving absolute navigational information from an external source (e.g., such as a satellite), means for obtaining speed or velocity information and an assembly of self-contained sensors capable of obtaining readings (e.g., such as relative or non-reference based navigational information) about the moving platform, and further comprising at least one processor, coupled to receive the output information from the receiver, sensor assembly and means for obtaining speed or velocity information, and operative to integrate the output information to produce a navigation solution. The at least one processor may operate to provide a navigation solution by using the speed or velocity information to decouple the actual motion of the platform from the readings of the sensor assembly.

Abstract: The present disclosure relates to methods of enhancing a navigation solution about a device and a platform, wherein the mobility of the device may be constrained or unconstrained within the platform, and wherein the navigation solution is provided even in the absence of normal navigational information updates (such as, for example, GNSS). More specifically, the present method comprises utilizing measurements from sensors (e.g. accelerometers, gyroscopes, magnetometers etc.) within the device to calculate and resolve the attitude of the device and the platform, and the attitude misalignment between the device and the platform.

Abstract: A portable navigation module and its method of operation are disclosed for seamlessly providing navigation and positioning information to a user. The module comprises: means, such as a GPS receiver, for receiving a first set of navigational information from an external source, such as satellites; and an inertial sensor unit for generating a second set of navigational information at the module. The navigational information is used by a processor programmed with a core algorithm, to identify the mode of conveyance algorithm and an orientation or misalignment algorithm. The algorithm utilizes the navigational information, aided by the mode of conveyance information and the orientation information, to produce a filtered navigation solution (which comprises position, velocity and attitude). The solution is suitably displayed, preferably on a detachable display unit.
