For example, the combined adjustment of CE-1
laser altimeter data and CCD image data can improve the spatial resolution of a topography model effectively [8, 9].
Unlike the traditional usage pattern of the altimeter, a
laser altimeter can be used to measure the range between satellites and some interested regions when used in combination with optical cameras.
Menenti and Ritchie [35] used a profiling
laser altimeter to predict aerodynamic roughness length of complex landscapes containing a mixture of grassland, shrub, and woodland areas, and found good agreement with field estimates.
"Claims suggesting Palm Jumeirah has sunk by 5mm, as detected by remote sensing (satellite) techniques, are not possible given that NASA's
laser altimeter satellites have an accuracy of only + or - 50 mm," he added.
This entered orbit on October 3 and by 2008 April had returned over six million precise
laser altimeter height measurements spaced on average 2.5km apart.
Other topics include radiation effects on stellar reference sensors, geolocation for the ICESat
laser altimeter, an autonomous walking inspection and maintenance robot, and a unification of artificial potential function guidance and optimal trajectory planning.

Laser Altimeter (LOLA) Measurement Investigation" principal investigator Dr.
Mission equipment includes low light-level camera, infrared line scanner, airborne video recorder and
laser altimeter. The ASN-206 system consists of one air vehicle, a power plant and a launch-and-recovery system.
The Mars Orbiter
Laser Altimeter orbited and mapped Mars for four-and-a-half years.
