"Farrell said these requirements can be achieved by combining GPS measurements with data from an inertial measurement unit (IMU) through an internal navigation system (INS). In the combined system, the GPS provides data to achieve high accuracy, while the IMU provides data to achieve high sample rates and high bandwidth continuously. Achieving centimeter accuracy requires "GPS carrier phase integer ambiguity resolution." Until now, combining GPS and IMU data to solve for the integers has been computationally expensive, limiting its use in real-world applications. The UCR team has changed that, developing a new approach that results in highly accurate positioning information with several orders of magnitude fewer computations." Grazie Martin, molto interessante anche se non รจ spiegato come ci siano riusciti. Speriamo venga implementato presto!
