DIFFERENTIAL GLOBAL NAVIGATION SATELLITE SYSTEM (DGNSS) ENHANCEMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240337759 titled 'DIFFERENTIAL GLOBAL NAVIGATION SATELLITE SYSTEM (DGNSS) ENHANCEMENT
The abstract describes a method for determining a terminal position using a differential global navigation satellite system (DGNSS) with satellite signals and corrections from a reference station.
- Utilizes GNSS signals from multiple satellite vehicles for positioning.
- Differential corrections from a reference station are used to improve accuracy.
- If the terminal position does not improve with corrections, they are temporarily interrupted.
- Interruption of corrections helps reduce power consumption and processing operations.
- DGNSS server selects corrections based on terminal capabilities like supported constellations and frequency bands.
Potential Applications: - Navigation systems for vehicles and vessels. - Location-based services for mobile devices. - Surveying and mapping applications. - Precision agriculture for crop monitoring. - Emergency response and search and rescue operations.
Problems Solved: - Enhances accuracy of terminal positioning. - Reduces power consumption and processing load. - Improves efficiency of GNSS-based applications.
Benefits: - Increased accuracy in determining terminal position. - Reduced power consumption for longer device usage. - Enhanced performance of location-based services. - Improved efficiency in various applications relying on GNSS technology.
Commercial Applications: Title: Enhanced Positioning System for Navigation Devices This technology can be utilized in commercial GPS devices for improved accuracy in navigation, surveying, and other location-based services. It can benefit companies in the transportation, agriculture, and emergency response sectors by providing more reliable and efficient positioning capabilities.
Questions about the technology: 1. How does the interruption of differential corrections help in reducing power consumption?
- The interruption stops the continuous processing of corrections, which saves energy by reducing the workload on the terminal.
2. What factors determine the selection of differential corrections by the DGNSS server?
- The server considers the terminal's supported GNSS constellations and frequency bands to choose the most suitable corrections for broadcasting.
Original Abstract Submitted
a terminal position is determined with differential global navigation satellite system (dgnss) using gnss signals from a plurality of satellite vehicles and differential corrections generated by a reference station for the gnss signals and broadcast via a dgnss server. the use of the differential corrections for positioning is interrupted when the determined terminal position does not improve with use of the differential corrections. the differential corrections may be interrupted for a period of time so that the terminal no longer receives the broadcast of the differential corrections or so that the differential corrections are not used for position estimation in order to reduce power consumption and reduce processing operations. the dgnss capabilities of the terminal, such as the supported gnss constellations and/or frequency bands, may be used by the dgnss server to select differential corrections to broadcast to the terminal.
