The spaceborne lidar experiment

Acta Astronautica, 1996
Abstract Lidar is one of the key sensors to understand global atmospheric environment, so lidar is one of the candidates to be flown on future earth observation satellites. But spaceborne lidar is our first trial and we have some technical issues to resolve before establishing operational sensor.

Spaceborne scanning lidar system (SSLS)

SPIE Proceedings, 2005
The Spaceborne Scanning Lidar System (SSLS) system is a space qualified scanning lidar system developed by MDA, Space Missions (MD Robotics) and Optech. It is scheduled to be launched in 2005 as part of a one year on-orbit demonstration of space technologies associated with spacecraft autonomous rendezvous and proximity operations.

LITE-the first spaceborne lidar

Conference Proceedings Second Topical Symposium on Combined Optical-Microwave Earth and Atmosphere Sensing, 2002
The first lidar in Earth orbit was recently flown aboard the Space Shuttle Discovery, September 9-20, 1994. The lidar In-space Technology Experiment (LITE) collected 45 hours of 3-wavelength atmospheric backscatter profiles during the 10-day mission. A wide variety of lidar measurements were made, including those of multi-level clouds, tropospheric and

A global product of fine-scale urban building height based on spaceborne lidar

arXiv.org, 2023
Characterizing urban environments with broad coverages and high precision is more important than ever for achieving the UN's Sustainable Development Goals (SDGs) as half of the world's populations are living in cities.

Cloud parametrization for spaceborne lidar applications

SPIE Proceedings, 1998
This paper discusses a cloud parameterization scheme for lidar application to cloud measurements by a space-borne lidar system. In lidar measurements generally the information on cloud particle size and number density is not available. Therefore, cloud parameterization becomes essential to derive from lidar observations the cloud optical parameters ...

Development of spaceborne LIDAR; ELISE (Experimental Lidar In Space Equipment)

Technical Digest. CLEO/Pacific Rim '99. Pacific Rim Conference on Lasers and Electro-Optics (Cat. No.99TH8464), 2003
The National Space Development Agency of Japan (NASDA) started a study on spaceborne lidar in 1990, and has developed a ground-based and an airborne lidar. Now they are to embark on the ELISE (Experimental Lidar In Space Equipment) which is the two-wavelength spaceborne backscatter lidar which will be loaded onto Mission Demonstration test Satellite-2 (

Spaceborne Lidar Mission, Past and Future

Conference on Lasers and Electro-Optics Europe, 1996
Laser rangefinders and atmospheric lidars use the same techniques. A short laser puls is transmitted and the reflected or scattered light is detected. Range resolved information of the targets or scatters is the output. To illustrate the use the mission, an example for a ground based system is given: A mission scenario on the highways is a good example.

Modeling spaceborne lidar returns from vegetation canopies

SPIE Proceedings, 2007
Structural and biophysical parameters of vegetation canopies, such as tree heights, biomass, vertical and horizontal heterogeneity are important factors affecting flows of energy, water, carbon and trace gases through terrestrial systems. Knowing such parameters is required to model processes associated with photosynthesis, energy transfer, and ...
