Data capture

• Scalar Absolute Gravimetry: The iCorus-iX gravimeter records gravity measurements across survey grids (typically spaced 1-2 km), achieving gravity anomaly accuracy within 1-2 mGal.
• Customizable Survey Design: Flight parameters are adjusted according to terrain and project requirements to ensure optimal data coverage.

Data processing and Geoid model generation

• Gravity Anomaly Reduction: Line-by-line processing with time domain filters to remove dynamic artifacts, to give in high-accuracy gravity anomalies.
• Least Squares Collocation (LSC): This technique is used to interpolate the gravity anomaly data onto a regular grid at the Earth’s surface (i.e. in three dimensions) and transform them into gridded geoid model values.
• Reference Surface Transformation: Customizable output options include the quasi-geoid or geoid, accommodating specific project needs through methods like Bruns’ equation or the Poincaré-Prey approach.
• Uncertainty Quantification: Propagating uncertainty estimates throughout the process ensures robust accuracy metrics for each model.

Enhanced Data Fusion for Accuracy

• Multisource Data Integration: Our processing can incorporate additional high-fidelity datasets (e.g. If the client has existing terrestrial gravity data or GNSS-leveled heights) to supplement airborne data, using data fusion methods for more robust geoid models.
