Airborne Future Magnetic Sensing | AIRGEO EXPLORATION & DISCOVERY

Airborne Future Magnetic Sensing and Navigation Systems

We’re not just building a AIRGEO MagBird QC Groundstation—we’re building a layered sensing system where today we visualise data, and in future the same architecture will interpret it and eventually use it for navigation and decision-making.

Field Intelligence Sensing System - Development

What We're Building Today

AIRGEO is developing real-time magnetic sensing systems for UAV-based geophysical surveys, combining low-noise instrumentation with live spatial visualisation and in-field quality control.

We are exploring at the forefront of emerging technologies and enhanced survey capabilities. The goal is to deliver World Class leading systems that provide real decision ready data, fast.

This is another reason we focus on real time data collection methodologies which we then apply leading diagnostic interpretability.

Already developed and ready for field testing (Screen shots below):

Additional developmental Imagery will be added as developed.

This is where our system is heading:

trend detection
anomaly detection
spatial projection
heading linkage
rate of change
spatial correlation
repeatability
map matching (observed vs known field)
drift correction
correlation filters

Emerging Capabilities

Real-time geospatial signal mapping
Live anomaly detection and trend tracking
Integrated sensor + spatial data interpretation
Operator feedback during acquisition

System Evolution

Current AIRGEO system development is focused on transitioning from data acquisition toward real-time environmental interpretation.

This includes the evolution from/to:

raw magnetic field measurement; to spatially aware signal mapping
toward interpreted field dynamics and anomaly detection
magnetic field as reference map
magnetic field as position correction signal

These developments form the foundation for future adaptive survey and sensing systems.

Forward-Looking Concepts

Longer-term research directions include the exploration of magnetic field-based navigation and positioning systems, particularly in environments where GNSS may be degraded or unavailable.

By combining magnetic sensing with inertial data and spatial mapping, such systems may provide complementary navigation capabilities for autonomous and assisted flight platforms.

Dual-Use Thinking

AIRGEO adopts a dual-use development philosophy, where systems designed for geophysical survey are also evaluated for broader sensing, navigation, and environmental intelligence applications.

As sensing systems become more integrated and intelligent, the distinction between survey instrumentation and navigation/perception systems continues to narrow.

DECISION / GUIDANCE ENGINE (FUTURE)

For UAV:

Adjust flight path
Slow down over anomalies
Auto-refly lines

For operators:

“Re-fly this segment”
“Increase line density here”
“Data degraded → investigate”
