A navigation method that includes receiving a satellite navigation signal from a satellite navigation system, determining a position based on the received satellite navigation signal, obtaining quality data indicative of a satellite navigation signal quality as a function of a location information, and correcting the determined position based on the satellite navigation signal quality.

A method for operating a GNSS sensor of a vehicle having control operations influenceable via an electronic control unit includes receiving satellite data, evaluating the satellite data, and deactivating at least one operating mode of the GNSS sensor when at least a portion of the satellite data is unsuitable for determining the position of the vehicle.

A driving safety enhancing system and method for making or enabling highly accurate judgment and providing advance early warning essentially include an information collection module for sensing, and thereby obtaining information about, the surroundings of a vehicle to which the system is applied; a processing unit for analysis and judgment; and a positioning and communication module for carrying out sharing and exchange of positioning signals and positioning information, thereby increasing the range within which targets can be sensed, and the number of targets that can be sensed, for analysis and judgment by the processing unit, the objective being to increase the accuracy of judgment and provide necessary warning as early as possible so that the driver of the vehicle will be warned of an imminent emergency in advance and can therefore drive comfortably and safely.

A server device includes an acquisition unit configured to acquire, from an in-vehicle device, a captured image obtained by capturing an image in front of a vehicle and imaging position information indicating a position where the captured image is captured, a holding unit configured to hold a model image, which is generated from a series of captured images including a vehicle turning at an intersection and includes a vehicle turning at the intersection as a model vehicle, in association with the imaging position information, and a providing unit configured to provide the model image to a vehicle scheduled to turn at the intersection corresponding to the model image.

A refuse vehicle includes a chassis supporting a plurality of wheels and a vehicle body. The vehicle body defines a receptacle for storing refuse. A lifting system is movable between a first position and a second position vertically offset from the first position. A processing unit is in communication with a sensor. An imaging device is in communication with the processing unit and is positioned on the refuse vehicle to have a field of view extending outwardly away from the refuse vehicle. The processing unit controls the imaging device to capture an image upon receiving an indication, from the sensor, that an indicator is present within the field of view. In some embodiments, the indicator is the presence of a positive object, like a waste container. In other embodiments, the indicator is the omission of an object (e.g., no container is detected) within the field of view.

A roadside assistance system and method. The system includes a user device and a plurality of provider devices, each including a display, an input mechanism, a GPS module, a wireless transceiver, a processor, a non-transitory computer readable medium operatively connected to the processor, and a logic stored in the non-transitory computer readable medium that, when executed by the processor, causes the system to perform a method. The method includes receiving information relating to current traffic conditions from a remote database, calculating an optimal service provider based on service provider locations, work status, and current traffic conditions, and displaying an estimated arrival time based on current traffic conditions. The system allows users to quickly and easily request roadside assistance with the assurance of an accurate arrival time.

A method, a device, and an electronic device for determining a positioning accuracy grade are provided. In the method, a predetermined list is created. The predetermined list is a list of at least one application with a positioning accuracy reaching up to a predetermined threshold. Operation preference information of a user operating is obtained a current third-party application selected from a plurality of third-party applications, which applies a positioning system in an electronic device. A positioning accuracy grade of the positioning system is determined correspondingly based on the operation preference information.

Disclosed is a method for achieving space-based autonomous navigation of global navigation satellite system (GNSS) satellites, and relates to the field of satellite navigation technologies. The method includes the following steps: optimizing a DRO, and establishing a dynamic model of an earth-moon space satellite orbit; establishing measurement links, by a low earth orbit (LEO) data relay satellite, with an earth-moon space DRO satellite and a GNSS respectively, and measuring an inter-satellite distance for modeling and linearization; adopting an extended Kalman filter (EKF) method to process inter-satellite measurement data, and autonomously determining a position and velocity of the global navigation satellite system without depending on the ground measurement and control support.

Satellite echoing for geolocation and mitigation of Global Navigation Satellite System (GNSS) denial are provided herein, where an example method comprises: transmitting, by a processing device, an echo message along a communication path having a communication satellite and a target device with an unknown distance to the communication satellite; receiving, by the processing device, a return of the echo message from the communication satellite over the communication path; determining, by the processing device, a time of travel of the echo message associated with only a single traversal of a portion of the communication path that is between the communication satellite and the target device; calculating, by the processing device, a distance between the communication satellite and the target device based on the time of travel; and performing, by the processing device, one or more actions based on the distance between the communication satellite and the target device.

Satellite relaying for geolocation and mitigation of GNSS denial are provided, where a method comprises: receiving, by a processing device from a communication satellite along a communication path, a message initiated at a transmission time by a transmitting device, the communication path having a target device with an unknown distance to the communication satellite; determining, by the device, a reception time upon receiving the message; determining, by the device, a time of travel of the message associated with only traversal of a portion of the communication that is path between the communication satellite and the target device based on a difference between the transmission time and the reception time; calculating, by the device, a distance between the communication satellite and the target device based on the time of travel; and performing, by the device, one or more actions based on the distance between the communication satellite and the target device.
