摘要： The disclosure notably relates to for determination of the altitude of a moving vehicle based on GNSS data and vehicle sensor data. The method comprises, in real-time obtaining a sensor vehicle pitch rate stemming from at least one vehicle sensor. The method also comprises, in real-time, while the GNSS signal is available, obtaining a GNSS vehicle pitch rate that stems from GNSS data of an altitude of the vehicle. The method also comprises, in real-time, calibrating the sensor vehicle pitch rate based on the GNSS vehicle pitch rate, the calibration being based on formulating the GNSS vehicle pitch rate as an affine function of the sensor vehicle pitch rate.

摘要： This application provides a positioning method and a positioning apparatus, and pertains to the field of intelligent driving technologies. The method includes: obtaining first positioning information, second positioning information, and third positioning information, where the first positioning information is obtained based on inertial navigation data, the second positioning information is obtained based on satellite positioning data, and the third positioning information is obtained based on visual positioning data; and when a vehicle travels in a first environment, performing first fusion processing on the first positioning information and the second positioning information, to obtain a first positioning result, where satellite signal quality in the first environment meets a preset quality requirement; or when a vehicle travels in a second environment, performing second fusion processing on the first positioning information and the third positioning information, to obtain a second positioning result, where satellite signal quality in the second environment does not meet a preset quality requirement. The foregoing method can be used to implement accurate, stable, and reliable positioning of the vehicle, and therefore improves driving safety of the vehicle.

摘要： A system and method for enhanced aircraft-based targeting senses RF emissions or other signals associated with a target while navigating a trajectory through a GPS-challenged airspace. While the target is being observed, the aircraft targeting system tracks GPS-challenged state vectors (e.g., via an onboard inertial reference system) and pressure altitudes consistent with each observation. When the aircraft emerges from the GPS-challenged airspace, the targeting system determines multiple GPS-driven subsequent absolute positions of the aircraft. The targeting system determines a refined estimate of the target location via batch factor graph optimization of measurements taken while inside and outside of the GPS-challenged airspace.

摘要： The present disclosure relates to a method, apparatus, medium, and device for positioning. When a predetermined switching condition is satisfied, a positioning result obtained by using a different positioning algorithm based on positioning data collected by a further selected sensor to position a movable object can be used as the positioning result of the movable object. When a autonomous driving vehicle leaves an area with high satellite signal quality and enters an area with low satellite signal quality, a positioning result of the vehicle obtained based on positioning data collected by a further selected sensor, which is different from a GPS receiver, can be used as the positioning result of the vehicle. In this way, when positioning the vehicle, the GPS positioning data with low positioning accuracy can be directly discarded, thereby effectively improving the accuracy of vehicle positioning.
