摘要： A method of determining location of a user device includes receiving global navigation satellite system (GNSS) fix data that represents GNSS calculated position of the user device. The method further includes receiving signal strength data associated with each satellite communicating with the user device, and receiving map information regarding environment surrounding the user device. The received GNSS fix data and signal strength data is provided to a non-linear filter, wherein the non-linear filter fuses the GNSS fix data and signal strength data to generate an updated position estimate of the user device. In addition, the non-linear filter utilizes probabilistic shadow matching estimates that represent a likelihood of received signal strength data as a function of hypothesized user device locations within the environment described by the received map information.

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： The present disclosure provides a method of analysing multiple signals transmitted by multiple discrete global navigation satellite systems for identifying information to be combined and delivered to a single-receiver user for use in an application. The method comprises analysing each of the signals to identify observed quantities of the signal. The observed quantities comprise information tracked by a network of receivers or by a single receiver. The method further comprises formulating full-rank observation equations from the observed quantities and determining inter-system biases (ISB) existing between the discrete satellite systems. In addition, the method comprises incorporating the inter-system biases into the full-rank observation equations to yield ISB-corrected observation equations, thereby allowing the multiple discrete global navigation satellite systems to be represented as a single global navigation satellite system and delivering the ISB-corrected observation equations to the single-receiver user.
