Instrument - Lidar/Laser Sounders
ALADIN
ALADIN, on board Aeolus, is a Direct Detection Doppler Wind Lidar operated in the ultraviolet range.
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
