PRECISE POINT POSITIONING (PPP)-BASED REAL TIME KINEMATIC (RTK) CORRECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17455630 titled 'PRECISE POINT POSITIONING (PPP)-BASED REAL TIME KINEMATIC (RTK) CORRECTION

Simplified Explanation

The patent application describes a device that uses Precise Point Positioning (PPP) correction information to generate Real Time Kinematic (RTK) correction information for RTK-based positioning.

  • The device obtains PPP correction information and generates RTK correction information by determining a virtual RTK base station location.
  • Based on the PPP correction information, the device generates a virtual Multi-Constellation Multi-Frequency (MCMF) measurement corresponding to the determined virtual RTK base station location.
  • The virtual MCMF measurement (and/or data derived from it) can be sent to other devices as RTK correction information.

Potential Applications

  • Surveying and mapping: The technology can be used in applications that require high-precision positioning, such as land surveying and mapping.
  • Autonomous vehicles: RTK-based positioning can enhance the accuracy of GPS-based navigation systems in autonomous vehicles.
  • Construction and infrastructure: The technology can be used in construction projects and infrastructure development that require precise positioning for alignment and measurement.

Problems Solved

  • Improved accuracy: By using PPP correction information to generate RTK correction information, the device can provide more accurate positioning data.
  • Real-time positioning: The technology enables real-time RTK-based positioning, allowing for immediate adjustments and feedback.

Benefits

  • Cost-effective: The device can generate RTK correction information without the need for physical RTK base stations, reducing infrastructure costs.
  • Wide coverage: The virtual RTK base station can be located anywhere, providing RTK correction information to devices in remote or inaccessible areas.
  • Scalability: The technology can be easily implemented in various devices and systems, allowing for scalability and widespread adoption.


Original Abstract Submitted

A device may use Precise Point Positioning (PPP) correction information to generate Real Time Kinematic (RTK) correction information that can be sent to other devices for RTK-based positioning. In particular, according to some embodiments, the first device having access to PPP correction information may obtain the PPP correction information and generate RTK correction information by determining a virtual RTK base station location and generating, based on the PPP correction information, a virtual Multi-Constellation Multi-Frequency (MCMF) measurement corresponding to the determined virtual RTK base station location. This virtual MCMF measurement (and/or data derived therefrom) can then be sent to other devices as RTK correction information.
