Base Station Location via Mobile Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location information systems require base stations to receive GPS signals to determine their location, which limits their installation in areas where GPS signals are unavailable, such as indoors, and necessitates additional hardware for each base station.
Innovation Solution
A location information system where base stations do not need to receive GPS signals, with a first mobile body estimating the location of each base station using its own location information and distance calculations, allowing the second mobile body to determine its location using the identified base station locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If base stations are equipped with GPS receivers to receive radio waves from GPS satellites for location determination, then location information can be obtained, but the device complexity and hardware requirements increase
Solution Approach 1:
The patent introduces a location obtainer device as an intermediary that performs GPS location measurements and shares the obtained location information with base stations. This mediator approach allows base stations to acquire location data without needing their own GPS receivers, thereby reducing hardware complexity while maintaining location information accuracy.
Solution Approach 2:
The location obtainer device serves multiple base stations simultaneously, performing the GPS reception function universally for the entire system rather than requiring each base station to have its own GPS receiver. This multi-functional approach reduces overall system complexity and hardware requirements.
2Adaptability or versatility
If base stations are required to receive GPS signals directly, then they can determine their location independently, but they cannot be installed in areas without GPS coverage such as indoors
Solution Approach 1:
The location obtainer acts as a mediator that receives GPS signals in areas with coverage and relays location information to base stations in areas without GPS coverage. This enables base stations to be installed indoors or in GPS-denied environments while maintaining their location determination capability through the intermediary's shared location data.
Solution Approach 2:
The location obtainer performs GPS location measurements in advance and stores or transmits the location information to base stations before they need it. This preliminary action allows base stations to obtain location data without performing their own GPS measurements, enabling installation in areas where GPS signals are unavailable.
3Measurement precision
If each base station is equipped with a GPS receiver, then location information can be obtained, but the cost and hardware requirements for each base station increase
Solution Approach 1:
The location obtainer serves as a centralized intermediary that handles GPS receiver functionality for the entire system. Base stations can be manufactured and deployed without integrated GPS receivers, simplifying their configuration and reducing per-unit costs, while the intermediary provides the necessary location information to all base stations.
Solution Approach 2:
Instead of each base station having its own GPS receiver, the system uses a single location obtainer to obtain location information once, then copies and distributes this location data to multiple base stations. This copying approach eliminates the need for redundant GPS hardware at each base station while maintaining location accuracy.
