LRR (Envisat)

The LRR instrument aboard Envisat was used to accurately determine the orbital height of the satellite.

scatterometers

WS (ERS-2)

The ERS-2 Wind Scatterometer obtained information on wind speed and direction at the sea surface.

a-altimeters

RA (ERS-2)

The RA on ERS-2 was a Ku-band nadir-pointing active microwave sensor designed to measure echoes from ocean and ice surfaces.
