INSTRUMENTS
Explore the many instruments the European Space Agency use to observe the Earth. ESA offer data from a wide range of optical, radar, atmospheric, altimetric and gravimetric instrumentation.
Instrument - Radar Altimeters
SIRAL
SIRAL (SAR Interferometer Radar Altimeter) is the primary instrument onboard ESA's CryoSat mission.
Instrument - Magnetic Field/Electric Field Instruments
EFI
The Electric Field Instrument (EFI) aboard the Swarm satellites is the first 3D ionospheric imager in space.
Instrument - MAGNETOMETERS
ASM
The Absolute Scalar Magnetometer on the Swarm satellites measures the strength of the magnetic field.
Instrument - MAGNETOMETERS
VFM
The Vector Field Magnetometer (VFM) is the primary instrument carried aboard the Swarm satellites.
Instrument - Interferometric Radiometers
MIRAS
The MIRAS instrument is a passive microwave 2-D interferometric radiometer onboard the SMOS satellite.
Instrument - Imaging Spectrometers/Radiometers
AATSR
The AATSR instrument aboard Envisat was primarily designed to measure Sea Surface Temperature.
Instrument - Imaging Radars
ASAR
ASAR ensures continuity with the image mode (SAR) and the wave mode of the ERS-1/2 AMI.
Instrument - Imaging Spectrometers/Radiometers
CHRIS
Compact High Resolution Imaging Spectrometer (CHRIS) provided data of spectral reflectances.
Instrument - Accelerometers
EGG
The main objective of GOCE's EGG was to measure the three components of the Gravity-Gradient Tensor.
Instrument - Cameras
HRC
The High Resolution Camera (HRC) is a black and white camera with a miniaturised telescope on the PROBA-1 mission.
Instrument - Imaging Spectrometers/Radiometers
MERIS
The MERIS instrument aboard Envisat was primarily dedicated to providing ocean colour measurements.

The RA-2 instrument aboard Envisat acquired radar altimetry data over ocean, land and ice surfaces.
Instrument - Spectrometers
SCIAMACHY
SCIAMACHY was an instrument on board the Envisat satellite that measured atmospheric chemistry.
Instrument - Imaging Spectrometers/Radiometers
Thermal Infra-Red Sensor (TIRS)
TIRS on Landsat-8 mission is a thermal imager that supplements observations from the OLI (Operational Land Imager) instrument.
Instrument - GPS
SSTI
SSTI was a state-of-the-art GPS receiver on GOCE that was designed to operate in a low-Earth orbit.
Instrument - GPS
GPSR and LRR (Swarm)
Each Swarm satellite is equipped with a Laser Retro-Reflector for external calibration and validation of the on-board GPS receiver.
Instrument - Accelerometers
ACC (Swarm)
The Accelerometer measures the Swarm satellite’s non-gravitational acceleration in its respective orbit.
Instrument - Radar Altimeters
STR (Swarm)
The Swarm Star Trackers retrieve information on the precise satellite orientation and attitude.
