Work on pulsed ranging lasers for satellite tracking started at Goddard about 1961/2. Its main purpose was to develop a high precision tracking system for ‘future’ needs. As it turned out it was in retrospect, a very fortunate step. As early as 1964, the first laser corner cube equipped spacecraft, Beacon Explorer-B, was launched into orbit and tracked with our laser ranging system. Tracking errors of several metres were obtained at this time. Over the last decade, considerable progress was…

Positioning by satellites

During the previous reporting period (1971–1974) accuracies of geodetic positioning by satellites had been pushed from the level of 5 meters rms or so characteristic of the NGS Worldwide Geodetic

Determination of the geocentric gravitational constant from laser ranging on near-Earth satellites

Laser range observations taken on the near-earth satellites of Lageos (a = 1.92 e.r.), Starlette (a = 1.15 e.r.), BE-C (a = 1.18 e.r.) and Geos-3 (a = 1.13 e.r.), have been combined to determine an

Reply to comments by Lerch et al. on ‘The Earth's shape and gravity field: a report of progress from 1958 to 1982’

The paper by Lambeck & Coleman (1983, L/C) to which Lerch, Klosko & Wagner (1986) take exception is a perspective, perhaps a slanted one, of important progress made in the observation of the Earth’s

A novel experimental technique and its application to study the effects of particle density and flow submergence on bed particle saltation

ABSTRACT A novel technique has been developed to measure bed particle flight durations and amplitudes using the impact data from the records of instantaneous pressure acting on multiple bed

Satellite altimetric measurements of the ocean. Report of the TOPEX Science Working Group

The scientific usefulness of satellite measurements of ocean topography for the study of ocean circulation was investigated. The following topics were studied: (1) scientific problems which use



Satellite laser ranging work at the Goddard Space Flight Center

The pulsed-laser satellite ranging systems presently being operated by the Goddard Space Flight Center are described along with their range and accuracy capabilities. The major subsystems are

Measurement of the lidar cross sections of cube corner arrays for laser ranging of satellites

The satellite coordinate system necessary to describe the location and orientation of each cube corner in the array is discussed. The method of optical testing is described along with the gain


spherically symmetric refractivity which varies exponentially with height. The correction is given as function of surface refractivity and ray elevation angle, and its accuracy and limitations are

Derivation of Closed Functions to Compensate Range and Angle Errors in an Exponential Atmosphere

It was shown by G. D. Thayer and J. J. Freeman that corrections to refraction-induced errors can be expressed in terms of error functions for propagation in an exponential model atmosphere. Using
