laser altimeter

The Laser Altimeter failed and was declared a lost cause.

A laser altimeter will be used to measure the distance from the spacecraft to the surface with the precision of several feet.

The laser altimeter can be retrofited to all models of this anti-ship missile family.

A laser altimeter is to measure the heights of mountains and depths of valleys.

A magnetometer and laser altimeter were considered for the mission, but were not ultimately flown.

Data from the spacecraft's laser altimeter gave scientists their first 3-D views of Mars' north polar ice cap.

IceSat was a laser altimeter equipped satellite, which could measure the freeboard of ice flows.

On November 9, Hayabusa performed a descent to 70 m to test the landing navigation and the laser altimeter.

A radar altimeter currently installed on WZ-10 is full interchangeable with laser altimeter.

It carried a SA-106 topographic camera, a laser altimeter and Doppler apparatus.

In an aircraft equipped with laser altimeters, the team in 1993 and 1994 measured the thickness of the ice across all of Greenland.

A novel laser altimeter on board BepiColumbo will survey the topography of Mercury to within a meter.

Laser altimeters are small and light weight and operate in the infra-red (IR) frequency band.

Laser altimeter and radar sounding data from orbiting spacecraft have identified a large number of basin-sized structures previously hidden in visual images.

Acuity laser altimeter.

A mapping camera, panoramic camera, and a laser altimeter were also included in the SIM bay.

The Stellar Camera was used during the runs of the Laser Altimeter on the night side of the Moon.

Instrument payload for an orbiter could include a radio subsystem, laser altimeter, magnetometer, Langmuir probe, and a mapping camera.

Laser Altimeter (LA)

A laser altimeter uses the round-trip flight-time of a beam of light at optical or infrared wavelengths to determine the spacecraft's altitude.

The Laser Altimeter could measure the height of the CSM above the lunar surface to within one meter.

Using an airborne laser altimeter, Haala, Brenner and Anders combined height data with the existing ground plans of buildings.

Laser altimeters or light detection and ranging (LIDAR)

And the spacecraft's laser altimeter, measuring variations in surface elevations, has given scientists a more detailed view of the terraced landscape of the north polar cap.

Furthermore, its laser altimeter's footprint was smaller than Chang'e 1's, achieving 5-meter vertical accuracy in its estimate of the Moon's radius.
