Solution Overview

Problem

Current altitude reporting systems for UAS are inaccurate, leading to potential collisions and inefficient airspace use due to reliance on GPS altitude or pressure-based measurements, which are relative and lack absolute altitude communication.

Innovation Solution

A system that combines hyperlocal weather data, satellite data, and sensory data from multiple UAS to establish a dynamic geospatial vertical datum, using crowdsourced data to reduce altitude uncertainty and enable consistent altitude reporting across different vehicle manufacturers, with a remote computing device solving a global system of equations to determine true altitudes and broadcast resolved models.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If GPS altitude or pressure-based altitude is used, then altitude measurement is simple, but altitude accuracy deteriorates

Engineering Contradiction:
Improvealtitude measurement systemVSAvoidaltitude accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent combines multiple altitude measurement systems (GPS, barometric pressure sensors from multiple UAS) into a unified crowdsourced altitude reference system. By merging data from multiple sources and using a global system of equations to resolve inconsistencies, the system achieves higher accuracy than any single sensor could provide alone.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a remote computing device that acts as an intermediary to process, validate, and resolve altitude data from multiple UAS. This intermediary system uses a global system of equations to determine accurate altitude references and broadcasts corrected altitude information back to vehicles, mediating between raw sensor data and reliable altitude information.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If pressure-based altitude is used, then relative altitude measurement is simple, but absolute altitude communication deteriorates

Engineering Contradiction:
Improvealtitude measurementVSAvoidabsolute altitude information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism where the remote computing device receives altitude data from multiple UAS, resolves it using a global system of equations, and broadcasts corrected altitude information back to the vehicles. This feedback loop transforms relative pressure-based measurements into accurate absolute altitude information that all vehicles can communicate and understand.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent creates a universal altitude reference system that works across different vehicle manufacturers and platforms. The crowdsourced approach and standardized resolution process enable any UAS equipped with pressure sensors to achieve accurate absolute altitude measurement and communication, making the system universally applicable.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If large vertical clearances are used between vehicles, then collision safety is improved, but airspace efficiency deteriorates

Engineering Contradiction:
Improvecollision avoidanceVSAvoidairspace utilization
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the mechanical approach of fixed vertical clearances with a computational system that uses global equation resolution and real-time altitude verification. Instead of relying on conservative fixed spacing, the system uses electronic computation to determine accurate relative altitudes and provides precise collision warnings only when necessary, replacing mechanical safety margins with intelligent computational assessment.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
