Satellite Positioning Validity Control via Usage-Type Criteria
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing satellite positioning systems face inefficiencies in determining the validity of positioning results due to uniform accuracy standards, leading to repetitive processes and reduced efficiency when different usage types require varying criteria for accuracy judgment.
Innovation Solution
An information processing device with a control unit that acquires data related to satellite positioning results and accuracy, using a reference value table to determine validity based on specific criteria tailored to each usage type, where criteria values can be set to 'MAX' for items not affecting judgment, allowing flexible determination of positioning result validity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If uniform accuracy standards are applied to all positioning results, then consistency in judgment criteria is maintained, but efficiency decreases due to repetitive processes and inability to adapt to different usage types
Solution Approach 1:
The patent applies dynamics by making the accuracy determination criteria changeable according to usage type. The control unit selects different predetermined criteria from a set of criteria based on the specific usage type, allowing the system to adapt dynamically rather than using fixed uniform standards. This resolves the contradiction by maintaining reliability through structured criteria selection while improving productivity through usage-type-specific optimization.
Solution Approach 2:
The patent changes the parameters of accuracy determination by introducing usage type as a variable. Different usage types have different predetermined criteria with different threshold values and judgment standards. This allows the system to maintain consistency within each usage type while improving overall efficiency by avoiding unnecessary strict checks for usage types that don't require them.
2Measurement precision
If multiple accuracy criteria are evaluated for all positioning results, then measurement precision is improved, but device complexity increases due to multiple judgment parameters
Solution Approach 1:
The patent segments the accuracy determination process by dividing it into usage type-specific criteria sets. Instead of evaluating all possible criteria for every positioning result, the system segments the criteria into groups based on usage types and only evaluates the relevant segment. This maintains measurement precision for each usage type while reducing device complexity by avoiding unnecessary criterion evaluations.
Solution Approach 2:
The patent applies local quality by having different accuracy criteria applied to different usage types. Each usage type has its own tailored criteria that are locally optimized for that specific application. This ensures high measurement precision where needed while reducing overall system complexity by not applying all criteria universally.
3Productivity
If usage type-specific criteria are implemented, then efficiency is improved by reducing repetitive processes, but device complexity increases due to multiple criterion sets
Solution Approach 1:
The patent applies preliminary action by pre-defining multiple sets of predetermined criteria for different usage types before runtime. The control unit stores these criterion sets in advance and simply selects the appropriate pre-prepared set based on the usage type, rather than creating or evaluating multiple criteria dynamically. This improves efficiency through pre-computation while managing device complexity through organized storage of criterion sets.
