Ranging performance of satellite laser altimeters

Topographic mapping of the earth, moon and planets can be accomplished with high resolution and accuracy using satellite laser altimeters. These systems employ nanosecond laser pulses and microradian beam divergences to achieve submeter vertical range resolution from orbital altitudes of several hundred kilometers. In this paper we develop detailed expressions for the range and pulse width meas...

GNSS Satellite Orbit Validation Using Satellite Laser Ranging

With a total of four new regional and global navigation satellite systems that have launched first satellites or even started an operational service, the GNSS landscape has experienced major changes in recent years. As part of the Multi-GNSS Experiment (MGEX) of the International GNSS Service (IGS), a global network of multi-GNSS monitoring stations has been established and various analysis cen...

Recent Developments in Testing General Relativity with Satellite Laser Ranging

The last decade can be characterized by an impressive diversity of techniques monitoring the artificial and natural satellite dynamics, as well as the Earth rotation: improved laser technology, renewed Doppler techniques, satellite radar altimetry, massive usage of the Global Positioning System (GPS), etc. Each of these techniques is optimally tailored to a specific type of application or scien...
