Measurement Definition: [Unit of measurement - n tesla]
| Instrument | Status/
Accuracy | Instrument Description | Measurement Technology | Timeline |
| GGAK-E | Operational | Monitoring and forecasting of solar activity, radiation and magnetic field in the near-Earth space, monitoring of natural and modified magnetosphere, ionosphere and upper atmosphere. | n/a |  |
| GGAK-M | Operational | Space Environmental Monitoring (SEM), heliogeophysical. | n/a | |
| GGAK-VE | Operational | Monitoring and forecasting of solar activity, radiation and magnetic field in the near-Earth space, monitoring of natural and modified magnetosphere, ionosphere and upper atmosphere. | n/a | |
| Magnetometer (GOES) | Operational | | n/a | |
| MGF | Operational +/-0.06 nT | The MGF consists of dual, tri-axial fluxgate magnetometers mounted on an 80-cm carbon fibre boom for measurements of magnetic field perturbations to a precision of 0.0625 nanotesla, from which to infer small-scale field-aligned currents. The MGF is turned on an average of 20% of the time, following a schedule devised by the science team. | n/a | |
| PlasMag | Operational | Magnetometer and plasma sensor to measure solar wind properties for forecasting geomagnetic storms. The Plasma-mag instrument comprises a Faraday Cup (measures solar wind) and a Fluxgate Magnetometer, as well as two space weather instruments: the Electron Spectrometer and the Pulse Height Analyzer. | n/a | |
| SSJ/5 | Operational | Measurement of transfer energy, mass, and momentum of charged particles through the magnetosphere-ionosphere in the Earth's magnetic field. | n/a | |
| SSM | Operational | Measures geomagnetic fluctuations associated with solar geophysical phenomena. With SSIES and SSJ provides heating and electron density profiles in the ionosphere. | n/a | |
| STR | Operational | Precise attitude determination from the combination of two or three star trackers. | n/a | |
| VFM | Operational | Magnetic field vector measurements. | n/a | |
| Advanced GGAK-M | Proposed | Space Environmental Monitoring (SEM). | n/a | |
| Magnetometer | Proposed | | n/a | |
