摘要： A positioning system comprises an onboard GNSS satellite receiver in a mobile element belonging to a user which estimates the position of said mobile element at various instants, a first processing module determining a consistency indicator by combining the estimated positions and data provided by secondary information sources, using a dynamic model of movement of the mobile elements to be positioned. The indicator is determined by comparing a speed, acceleration, gyration triplet derived from direction and velocity measurements taken by the mobile element, to a dynamic model of movement of an object, vehicle, person or animal to be positioned. The system comprises a consolidation module containing means storing the positions estimated at various instants, a digital filter to obtain a filtered position from the stored positions of a user, the consistency indicator calculated from filtered positions; and detection means determining from the consistency indicator whether the estimated positions are falsified.

摘要： An on-board unit includes a satellite information acquiring section and a processing section. The satellite information acquiring section is configured to output first time data showing current time based on a satellite signal received from an artificial satellite. The processing section is configured to acquire second time data showing current time based on a radio signal which is different from the satellite signal, and to detect a spoofing based on a difference of a time shown by the first time data and a time shown by the second time data.

摘要： A pay television satellite broadcast includes validation data that can be used to validate authenticity of live global positioning system (GPS) data. The validation data may be included within entitlement messages and encrypted for security and selective reception by authorized receivers. A navigation system may compute checksums of received live GPS data and compare with the validation data for a match. A decision about whether or not to use the live GPS data may be taken based on whether or not the computed checksums match the validation data received via the pay television satellite broadcast signals.

摘要： A system and method to determine the location of an interfering signal source within a few meters. Three or more networked GNSS receivers are located at known locations and used to simultaneously collect and time-stamp data samples at L1 and L2. The data samples are passed over the network to a server which identifies samples associated with an interfering signal, cross correlates associated samples from pairs of receivers, and applies a discriminator function to significantly improve the accuracy of a computed time difference of arrival (TDOA) for the interfering signal, thereby significantly improving the accuracy of the location determination.

摘要： Disclosed is a device and method for determining the direction of a false Global Navigation Satellite System (GNSS) satellite signal transmitter. False GNSS satellite signals can be used malevolently to take control of a rigid body such as a vehicle or ship that is using GNSS satellite signals for navigation. The GNSS device according to the invention computes a plurality of range differences, where each range difference is the difference between a range from a first GNSS satellite to a first GNSS antenna, and the range from the first GNSs satellite to a second GNSS antenna. Each of the plurality of range differences is correlated to a rotation angle of a baseline vector extending from the first GNSS antenna to the second GNSS antenna. The rotation angles and their corresponding range differences can be used to indicate the direction of the false GNSS satellite signal transmitter.
