Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current GPS technologies, such as GNSS, struggle to provide accurate location services for user devices, especially in environments with high error biases and limited resources, falling short in applications like autonomous vehicles and precision advertising due to sub-meter accuracy limitations.
Innovation Solution
Implementing a hyper accuracy location platform that utilizes a network of reference base stations, real-time analysis of space and terrestrial biases, and cloud-based processing of carrier-phase observables to provide centimeter-level accuracy, even for low-end GPS receivers, by calculating location corrections and actual positions through a system of user devices, base stations, and reference receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS-based location technology is used, then location services can be provided to user devices, but the position accuracy is limited to several meters at best due to satellite biases and terrestrial errors
Solution Approach 1:
The patent introduces base stations as intermediary components that receive GPS signals and perform local processing to determine precise locations. These base stations act as mediators between GPS satellites and user devices, computing location corrections based on known base station positions and signal analysis, thereby improving position accuracy while maintaining system reliability
Solution Approach 2:
The patent replaces the traditional direct satellite-to-device GPS mechanism with a hybrid system that incorporates base station infrastructure. Instead of relying solely on satellite signals processed by individual devices, the system substitutes a networked approach where base stations perform centralized signal processing and correction calculations
2Ease of operation
If network-based positioning approaches are used, then location can be determined using cell tower connections, but the accuracy degrades to fifty meters at best or kilometer accuracy at worst
Solution Approach 1:
The patent merges GPS satellite-based positioning with network-based positioning by having base stations perform both GPS signal processing and cellular network functions. This combination allows the system to leverage the precision of GPS measurements while utilizing the widespread coverage and ease of connection provided by cellular networks
Solution Approach 2:
The patent segments the positioning function into separate components: base stations perform GPS signal processing and location calculation, while user devices simply provide connection requests and receive location information. This segmentation allows complex processing to be centralized at base stations while keeping device requirements simple
3Quantity of substance
If consumer-grade GPS receivers are used, then devices can achieve position accuracy of around three meters, but they cannot provide sub-meter accuracy required for applications like autonomous vehicles
Solution Approach 1:
The patent uses base stations as intermediaries that enhance the capabilities of consumer-grade receivers. The base stations perform sophisticated signal processing and correction calculations that would be too complex for individual consumer devices, thereby enabling sub-meter accuracy through the intermediary processing infrastructure
Solution Approach 2:
The patent changes the operational parameters of GPS receivers by having them connect to base stations that provide corrected position information. Instead of relying on individual device processing power, the system changes the parameter of where and how location calculations are performed, achieving higher accuracy through networked processing
Data Source
AI summary
A device receives reference data from reference receivers associated with base stations, and synchronizes the reference data to a reference time to generate synchronized reference data for the reference receivers. The device processes the synchronized reference data to determine location error information associated with one or more of the reference receivers, and receives information indicating that a user device, located at an observed location, connects to a particular base station of the base stations. The device determines a location correction for the observed location, or an actual location of the user device, based on particular location error information for a particular reference receiver, of the reference receivers, associated with the particular base station, and causes information identifying the location correction or information identifying the actual location of the user device to be provided to the user device.
