scientific highlights

Heritage data still widely used today

For about 30 years now, ESA satellites have been cruising some 800 km above our heads, collecting information about our planet-but why are older missions still so fundamental today?

Missions

Explore the European Space Agency's Earth Observation satellite missions. Learn all about ESA's dedicated Earth Explorers or collaborations with other agencies through the Third Party Missions programme.

Swarm
earth explorers

Swarm

Swarm is dedicated to creating a highly detailed survey of the Earth’s geomagnetic field and its temporal evolution as well as the electric field in the atmosphere using a constellation of three identical satellites.

ACTIVITY - quality

TIRO

Topside Ionosphere Radio Observations from multiple LEO-missions (TIRO) project will provide two measurements from onboard instruments of LEO satellite missions: TEC (Total Electron Content) derived from GNSS signals, and electron density derived from KBR (K-Band Ranging) system observations.

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.

p-magnetic-field-electric-field-instruments

STR (Swarm)

The Swarm Star Trackers retrieve information on the precise satellite orientation and attitude.

p-magnetic-field-electric-field-instruments

ACC (Swarm)

The Accelerometer measures the Swarm satellite’s non-gravitational acceleration in its respective orbit.

p-magnetic-field-electric-field-instruments

GPSR and LRR (Swarm)

Each Swarm satellite is equipped with a Laser Retroreflector for external calibration and validation of the on-board GPS receiver.
