Satellite Laser Ranging and its Applications

Celestial Mechanics, 1985
Satellite laser ranging (SLR) provides an important capability for precise orbit determination and for geophysical parameter estimation to support a number of contemporary geodynamic and oceanographic investigations. The precision of the SLR measurement has improved from the early meter-level systems to the current capabilities of a few centimeters for

Satellite Laser Ranging

2015
Satellite Laser Ranging (SLR) is currently the unique technique to determine station coordinates, Earth Orientation Parameters (EOPs) and Stokes coefficients of the Earth’s gravity field from one observation equation with a high accuracy. These parameters form the so-called ‘three pillars’ (Plag and Pearlman, 2009) of the Global Geodetic Observing ...

Korea's first satellite for satellite laser ranging

Acta Astronautica, 2005
Abstract Science Technology Satellite-2 (STSAT-2) has been developed since October 2002 as a sequel mission to KAISTSAT-4 (STSAT-1). STSAT-2 is scheduled to be launched into an ellipsoidal orbit of 300 km × 1500 km in December 2005 by the first Korea Satellite Launch Vehicle KSLV-1.

Corrections for atmospheric refractivity in satellite laser ranging

Applied Optics, 1977
The range correction calculated from ground-level meteorological measurements is shown to consist of a series of terms. The zeroth order term of this series corresponds to the correction obtained under the assumption of a spherically symmetric refractivity profile.

Local geodesy by satellite laser ranging: a European solution

manuscripta geodaetica, 1995
Errors in the modelling the satellite orbit have so far limited the accuracy in the processing of Satellite Laser Ranging (SLR) data. A new method is proposed to achieve a residual size consistent with the observational errors, and a stability of the geodetic network coordinates at the same level.

Optical Metrology Terminal for Satellite-to-Satellite Laser Ranging

2022
Interferometric laser ranging is a powerful enabling technology for high-precision satellite-to-satellite tracking within the context of Earth observation, gravitational wave detection, and formation flying. Since the launch of the gravity field mission GRACE Follow-On in 2018, the onboard Laser Ranging Interferometer has successfully been operating as

Satellite Laser Ranging

2010
Determining the range to a satellite in orbit around the earth utilising the technique of satellite laser ranging (SLR) was pioneered in the early 1960s. The first successful ranging experiment was reported in the 3 December 1964 issue of Flight International (Smith 1964). Dr. Henry H. Plotkin of Goddard Space Flight Centre led a NASA team to track the

Gravitomagnetic interaction and laser ranging to Earth satellites

Physical Review Letters, 1988
The contribution of the ``gravitomagnetic'' interaction to a well-measured perturbation term in the orbits of Earth satellites is calculated. Laser-ranging determination of the Moon's orbit and Lageos-satellite orbit require the precise participation of the gravitomagnetic interaction; otherwise anomalous orbital perturbations exist.

Receiver design for laser ranging to satellites

IEEE Transactions on Instrumentation and Measurement, 1981
The paper provides a quantitative basis for receiver design whereby timing performance can be evaluated for an arbitrary impulse response using known or measurable system parameters. The analysis accounts for the statistical independence of the multiplication processes of the dynodes as well as the possibility of their non-Poisson behavior.

Satellite and lunar laser ranging in infrared

SPIE Proceedings, 2017
We report on the implementation of a new infrared detection at the Grasse lunar laser ranging station and describe how infrared telemetry improves the situation. We present our first results on the lunar reflectors and show that infrared detection permits us to densify the observations and allows measurements during the new and the full moon periods ...
