Satellite Laser Ranging in Egypt

NRIAG Journal of Astronomy and Geophysics, 2015
AbstractThe paper concerns on the satellite laser ranging (SLR) in Egypt. The three generations which can be loosely defined by their single shot root mean square precision, are discussed. The laser generators used at the Helwan half automatic and full automatic stations are described.

1.06 μm wavelength based high accuracy satellite laser ranging and space debris detection

, 2020
Classical satellite laser ranging (SLR) technology based on 532 nm wavelength usually adopts low energy laser to measure cooperative objects. However, for a very weak target, such as debris and lunar reflector arrays, laser ranging system should have ...

Measuring the relativistic perigee advance with Satellite Laser Ranging

, 2002
One of the most famous classical tests of General Relativity is the gravitoelectric secular advance of the pericenter of a test body in the gravitational field of a central mass. In this paper we explore the possibility of performing a measurement of the
