Embodiment Construction

[0025] refer to figure 1 , which shows a block diagram of a system 50 according to an embodiment of the invention. System 50 generally includes a plurality of vehicles 52 a - 52 n , a network 54 , satellites 56 and a base station 58 . Each vehicle 52a-52n includes at least one device of the plurality of devices 100a-100n. For example, vehicle 52a includes device 100a. combine figure 2 Device 100a is described in more detail.

[0026] Device 100a may be connected to both network 54 and / or satellite 56 . Connection to network 54 may be accomplished through a cellular network connection (eg, 3G, 4GLTE, etc.), a Wi-Fi connection, and / or other types of connections. Connection to satellite 56 may be achieved through a GPS type connection. Connection to network 54 may allow device 100a to receive information, such as correction values, from a reference device (eg, one or more devices 100b through 100n operating in reference device mode, base station 58, etc.).

Abstract

The present invention provides a device including an antenna, a processor and a memory. The antenna may be configured to connect to (i) a wireless network and (ii) GPS satellites. The processor may be configured to execute instructions. The memory may be configured to store the instructions. When executed, the instructions may perform the step of locating a reference device connected to the wireless network. The reference device has (a) an identification code and (b) a calibration value. The instructions are executable to determine whether the correction value passes a quality check. If the correction value passes the quality check, the correction value is used to compensate for local conditions when connecting to the GPS satellites.

Description

technical field [0001] The present invention generally relates to the Global Positioning System (GPS), and more particularly relates to a method and / or device for realizing an ad hoc real-time dynamic roaming network of vehicles in the GPS system. Background technique [0002] Conventional GPS systems typically use real-time kinematic (RTK) to provide fixed ground-based reference stations. Conventional systems use expensive sensors to improve the accuracy of standard GPS. Such systems are useful for providing centimeter-level accuracy in agricultural applications and land surveying applications. Conventional automotive Global Navigation Satellite System (GNSS) receivers employ positioning solutions with sensor-based dead reckoning technology to maintain an accuracy of up to 5 meters in open environmental conditions. Next-generation automotive localization solutions may require higher accuracy to safely detect lanes and / or support autonomous driving. Conventional systems d...
