blue arrow Instrument Overview

ASM

The Absolute Scalar Magnetometer (ASM) carried aboard the Swarm satellites measures the strength of the magnetic field to greater accuracy than any other magnetometer. It provides scalar measurements of the magnetic field to calibrate the Vector Field Magnetometer (VFM).

The instrument was developed by the French Space Agency (CNES) and the French Atomic Energy Commission.

blue arrow DATA TOOLS

VirES
VirES for Swarm, the virtual research service, is a highly interactive data manipulation and retrieval interface for Swarm constellation mission products. It includes tools for studying various geomagnetic models by comparing them to the Swarm satellite measurements at given space weather and ionospheric conditions.
