LAM (laser altimeter
) deployed on CE-1 obtained about total 9.12 million measurements covering the whole lunar surface.
Optimization of an airborne laser altimeter
for remote sensing of vegetation and tree canopies.
An earlier report, based on laser altimeter
data, said there was obvious evidence that there once were oceans of surface water on Mars.
Planetary scientists are moving closer to an understanding of Martian water thanks to the Mars Orbiter laser altimeter
. The altimeter, an instrument on the Global Surveyor satellite, helps scientists map the topography (physical features) of Mars' surface by measuring the altitude (height) of landforms (see SW 9/20/99, p.
This paper reviews the application of an airborne laser altimeter
for measuring vertical features and patterns of the landscape surface at Walnut Gulch Watershed.
More specifically, the UK's Ministry of Defense describes the program's objectives as being the creation of a system capable of "detecting obstacles, terrain following, true air-speed measurement and ground air target characterization." Work to date includes French avionics contractor Sextant testing a laser air-speed measurement system aboard a Mirage III testbed aircraft and the UK's Thorn EMI working on laser altimeter
and helicopter obstacle warning systems.
This instrument can be found on top of the lander so once it successfully makes a lunar landing, NASA's Lunar Reconnaissance Orbiter can launch a laser altimeter
at it to pinpoint the Beresheet's location.
This survey also provides the first opportunity for the OSIRIS-REx Laser Altimeter
(OLA), an instrument contributed by the Canadian Space Agency, to make observations now that the spacecraft is in proximity to Bennu.
ICESat-2 will carry a single instrument, the Advanced Topographic Laser Altimeter
System (ATLAS), which will send 10,000 laser pulses a second to Earths surface and measure the height of ice sheets, glaciers, sea ice and vegetation by calculating the time it takes the pulses to return to the spacecraft.
New observations of Mercury's northern polar regions come from MESSENGER's laser altimeter
, which maps the planet's topography and measures how reflective the surface is.
MARYLAND (CyHAN)- MESSENGER's Mercury Laser Altimeter
sends out laser pulses that hit the ground and return to the instrument.
The spacecraft has a camera to make wide and narrow angle images of Mars, and a laser altimeter
to measure the height and depth of surface features by bouncing pulses of light off the planet.
