The present disclosure relates to a contextual service device and method of use to identify an operator's needs, such as in the event a vehicle crash, vehicle breakdown, theft, and/or vehicle related quarry in real time. In various aspects, the device is self-sufficient and may be installed and activated in a single step. Furthermore, the device is not reliant upon external systems of components of the vehicle to operate and may be updated over the air to improve cash detection accuracy.

A positioning method and an on-board device. The method includes: acquiring positioning data of a vehicle from a satellite and positioning correction data from a base station; acquiring target positioning data of the vehicle by correcting the positioning data based on the positioning correction data; and sending the target positioning data to a terminal device to enable the terminal device to position the vehicle according to the target positioning data.

A method for detecting a presence of interference during global navigation satellite system (GNSS)-based and inertial sensor signals (INS)-based localization of a vehicle includes determining localization results using a first filter configured to read in GNSS data and INS data, and storing a plurality of the determined localization results. The plurality of the determined localization results are after one another in terms of time and are each determined using the first filter. The method further includes analyzing the stored plurality of localization results using a second filter which differs from the first filter.

A method or system can include or be configured to receive a set of satellite observations, receiving sensor data, determining a position estimate and associated positioning error for a rover based on the set of satellite observations and the sensor data, determine a protection level associated with the position estimate based on a set of potential faults, and optionally provide an alert when the positioning error exceeds the protection level.

Provided is a triggering system for triggering a plurality of vehicle-mounted cameras for obtaining a set of images. The present invention further relates to a camera system including the same. The triggering system includes a central unit and a plurality of camera controllers that each control one or more cameras. The present invention proposes a combination of a de-centralized updating process to determine the respective triggering time instants for the cameras, and a local timer in each of the camera controllers that is repeatedly synchronized using GNSS time information. This allows better control of the position of the entrance pupils of the cameras at the time of recording images. This will in turn produce a set of images that enables the generation of a panoramic image having less parallax-related errors.

A traffic radar system comprises a first radar transceiver, a second radar transceiver, a speed determining element, and a processing element. The first radar transceiver transmits and receives radar beams and generates a first electronic signal corresponding to the received radar beam. The second radar transceiver transmits and receives radar beams and generates a second electronic signal corresponding to the received radar beam. The speed determining element determines and outputs a speed of the patrol vehicle. The processing element is configured to receive a plurality of digital data samples derived from the first or second electronic signals, receive the speed of the patrol vehicle, process the digital data samples to determine a relative speed of at least one target vehicle in the front zone or the rear zone, and convert the relative speed of the target vehicle to an absolute speed using the speed of the patrol vehicle.
