  • Publication number: 20200204956
    Abstract: Embodiments of the disclosure provide methods and systems for determining a position of a terminal device. The system may include a receiving module configured to receive current position information associated with the terminal device, the current position information including one or more positions indicative of the present location of the terminal device. The system may further include an acquisition module configured to acquire historical position information associated with the terminal device, said historical position information being separated from the current position information by a predetermined time interval. The system may further include a determination module configured to determine, based on the historical position information, an actual position of the terminal device from the current position information.

  • Publication number: 20200149893
    Abstract: Embodiments of the present disclosure are directed to systems and methods for determining a vehicle orientation. In one implementation, a computer-implemented method for determining a vehicle orientation may include receiving a first set of satellite signals associated with a connected device positioned relatively stationary with respect to a vehicle. The method may also include determining that the first set of satellite signals is insufficient to determine the vehicle orientation. The method may further include determining the vehicle orientation based on a first relative orientation of the connected device relative to the vehicle and a second relative orientation of the connected device relative to a reference object.
