Embodiment Construction

[0025] reference figure 1 , Which shows a block diagram of a system 50 according to an embodiment of the present invention. The system 50 generally includes multiple vehicles 52a to 52n, a network 54, a satellite 56 and a base station 58. Each vehicle 52a to 52n includes at least one device among a plurality of devices 100a to 100n. For example, the vehicle 52a includes the device 100a. Combine figure 2 The device 100a is described in more detail.

[0026] The device 100a may be connected to both the network 54 and / or the satellite 56. The connection to the network 54 may be achieved through a cellular network connection (for example, 3G, 4G LTE, etc.), Wi-Fi connection, and / or other types of connections. The connection to the satellite 56 can be achieved through a GPS type connection. The connection to the network 54 may allow the device 100a to receive information such as correction values ​​from a reference device (e.g., one or more devices 100b to 100n operating in refer...

Abstract

An apparatus comprising an antenna, a processor and a memory. The antenna may be configured to connect to (i) a wireless network and (ii) a GPS satellite. The processor may be configured to execute instructions. The memory may be configured to store the instructions. When executed, the instructions may perform a step of locating a reference device connected to the wireless network. The reference device may have (a) an identification code and (b) a correction value. The instructions may perform a step of determining whether the correction value passes a quality check. If the correction value passes the quality check, the correction value may be used to compensate for local conditions when connecting to the GPS satellite.

Description

Technical field [0001] The present invention generally relates to a global positioning system (GPS), and more specifically, to a method and / or device for realizing a self-organized real-time dynamic roaming network of a car in the GPS system. Background technique [0002] Conventional GPS systems usually use real-time kinematics (RTK) to provide a fixed ground-based reference station. 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 use positioning solutions with sensor-based dead reckoning technology to maintain an accuracy of up to 5 meters in open environment conditions. Next-generation car positioning solutions may require higher accuracy in order to safely detect lanes and / or support autonomous driving. Conventional systems do not support ...
