摘要： Provided is a position correction apparatus which includes: a predictive position calculation unit structured to calculate a predictive position of a mobile object, with reference to a speed of the mobile object having been acquired in a current cycle; an error judging unit structured to calculate a relative position vector that indicates a relative position between a GNSS position acquired in a current cycle and a predictive position derived from the speed having been acquired for the previous time, and to judge that the acquired GNSS position is free of error, if the speed of change, from a relative position vector having been calculated in a cycle prior to the previous time, to the relative position vector calculated in the current cycle, is smaller than a predetermined speed threshold value; a correction amount calculation unit structured to calculate a correction speed vector which is a speed vector derived from the relative position vector, the relative position vector having been calculated for the previous time, and a duration of time from a time point the relative position vector was calculated for the previous time up to the current cycle, if the GNSS position has been judged to be free of error, and a current position calculation unit structured to calculate, as the current position of the mobile object, a position obtained by correcting the predictive position calculated in the current cycle, with an integrated value of the correction speed vector.

摘要： A Global navigation satellite-based systems (GNSS) enabled device, handling at least two of a plurality of sensors, collects GNSS measurements and navigation related non-GNSS sensor data. The collected navigation related non-GNSS sensor data is automatically formatted into a data format that is compatible with a format of the GNSS measurements. The formatted navigation related non-GNSS sensor data and the GNSS measurements are utilized by a single function to compute navigation information for the GNSS enabled device regardless of sensor configurations such as a cellular radio and/or a motion sensor. Measurement errors in the collected navigation related non-GNSS sensor data is estimated to determine measurement accuracy. The collected navigation related non-GNSS sensor data is selectively adopted, combined with the GNSS measurements, to compute navigation information by the single function based on the determined measurement accuracy. The computed navigation information may be utilized to calibrate sensor and/or sensor data when needed.

摘要： Significant, cost-effective improvement is introduced for Position, Navigation, and Timing (PNT) on a global basis, particularly enhancing the performance of Global Navigation Satellite Systems (GNSS), an example of which is the Global Positioning System (GPS). The solution significantly improves performance metrics including the accuracy, integrity, time to acquire, interference rejection, and spoofing protection. A constellation of small satellites employing a low-cost architecture combined with improved signal processing yields an affordable enabler for spectrum-efficient transportation mobility. As air traffic management modernization transitions to a greater dependence on satellite positioning, the solution provides aviation users new protections from both intentional and unintentional interference to navigation and surveillance. And in response to an era in which intelligent transportation is under development for automobiles, reliable where-in-lane positioning enables new applications in connected and autonomous vehicles. New military capability increases PNT availability.

摘要： Disclosed is a method performed by a position calculation node (160) in a wireless communication network (100). The node (160) is arranged for improving accuracy when determining positions in the wireless communication network. The method comprises obtaining a signal transport time value for each of a plurality of different geographical UE positions (UE1, UE2, UE3), wherein the respective signal transport time value relates to the time it takes for a radio signal to travel between a first base station and one of the plurality of UE positions. The method further comprises obtaining a geographical position value for each of the plurality of different geo-graphical UE positions, the position values being independent of the signal transport time values, and determining an actual geographical position for the first base station, based on the obtained signal transport time values, the obtained position values and a predefined geographical position for the first base station.
