Satellite Laser Ranging in Egypt [PDF]

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.

Optical metrology terminal for satellite-to-satellite laser ranging [PDF]

International Conference on Space Optics — ICSO 2018, 2019
Interferometric laser ranging is an enabling technology for high-precision satellite-to-satellite tracking within the context of earth observation, gravitational wave detection, or formation flying. In orbit, the measurement system is affected by environmental influences, particularly satellite attitude jitter and temperature fluctuations, demanding an

Ranging performance of satellite laser altimeters [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 1992
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 submetre vertical range resolution from orbital altitudes of several hundred kilometres.

Satellite laser ranging to GPS and GLONASS [PDF]

Journal of Geodesy, 2015
Satellite laser ranging (SLR) to the satellites of the global navigation satellite systems (GNSS) provides substantial and valuable information about the accuracy and quality of GNSS orbits and allows for the SLR-GNSS colocation in space. In the framework of the NAVSTAR-SLR experiment two GPS satellites of Block-IIA were equipped with laser ...

Satellite Laser Ranging System at Geochang Station [PDF]

Journal of Astronomy and Space Sciences, 2018
Korea Astronomy and Space Science Institute (KASI) has been developing the space optical and laser tracking (SOLT) system for space geodesy, space situational awareness, and Korean space missions. The SOLT system comprises satellite laser ranging (SLR), adaptive optics (AO), and debris laser tracking (DLT) systems, which share numerous

Satellite Laser-Ranging as a Probe of Fundamental Physics. [PDF]

Sci Rep, 2019
AbstractSatellite laser-ranging is successfully used in space geodesy, geodynamics and Earth sciences; and to test fundamental physics and specific features of General Relativity. We present a confirmation to approximately one part in a billion of the fundamental weak equivalence principle (“uniqueness of free fall”) in the Earth’s gravitational field,
