Compact satellite ranging laser subsystem
IEEE Journal of Quantum Electronics, 1978This letter describes a compact ruby oscillator-amplifier system suitable for satellite ranging. The laser is comprised of an ellipsoidal pump cavity which contains two laser rods and flashlamps.

Gravitomagnetic interaction and laser ranging to Earth satellites
Physical Review Letters, 1988The 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.

Pulse spreading and range correction analysis for satellite laser ranging
Applied Optics, 1990The pulse spreading resulting from light detection and ranging measurements of the range to earth-orbiting satellites is described. An analysis quantifying this pulse spreading and the calculation of corrections to be applied to the lidar range determination of satellites is detailed.

Satellite and lunar laser ranging in infrared
SPIE Proceedings, 2017We 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 ...

Receiver design for laser ranging to satellites
IEEE Transactions on Instrumentation and Measurement, 1981The 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.

Studies Of Laser Ranging To The TOPEX Satellite
SPIE Proceedings, 1988A collaborative effort of NASA and CNES will lead to the launching of the 'TOPEX' ocean topography experiment satellite in the early 1990s; the satellite will employ two onboard altimeters whose calibration may be accomplished by a worldwide lidar tracking network that is projected to enter into operation in the 1990s. Attention is presently given to a
