IFR Icon

IFR — In-Field Referencing

In-Field Referencing (IFR) is the determination of magnetic field values — typically declination, dip angle, and total field — in the region of interest. FGS combines high-quality space-based measurements from satellites with local survey measurements taken by aircraft and ships to build state-of-the-art models of crustal anomalies.

Virtual Observatory Icon

FGS Virtual Observatory

VirtualOBS combines a global model which provides the large-scale behavior of the external magnetic field with real-time measurements from satellites and ground stations to provide local corrections to the global model for drilling operations.

The Founder

Manoj Nair

Manoj Nair

Founder & Principal Scientist

Dr. Manoj Nair is an internationally recognized expert in geomagnetic field modeling and space weather. With decades of experience at CIRES, University of Colorado and NOAA's National Centers for Environmental Information, he is a founding scientist of NOAA/CIRES's High-Definition Geomagnetic Model (HDGM) — the industry standard high-resolution geomagnetic model for the directional drilling industry.

His expertise spans satellite magnetic measurements, ionospheric current systems, machine learning for geomagnetic disturbance forecasting, and real-time magnetospheric disturbance field modeling.

Flatirons Geomagnetic Services LLC is based in Boulder, Colorado, bringing deep geomagnetic expertise to industry and scientific clients globally.
