The motions of artificial satellites are influenced by gravitational and non-gravitational pertur­ bations . Of special interest among the gravitational perturbations is the anisotropy of the earth ' s gravitational field. Orbits of geostationary satellites are extremely sensitive to perturba­ tions caused by the earth ' s equatorial ellipticity, which is described by the coefficients C22 and S22 in the harmonic series expansion of the geopotential. These coefficients cause resonant…

Status of Geodetic Astronomy at the Beginning of the 21st Century

At the beginning of the 21st century, a significant technological change took place in geodetic astronomy. The use of digital imaging sensors strongly improved the degree of automation, efficiency

The Digital Zenith Camera - A New High-Precision and Economic Astrogeodetic Observation System for Real-Time Measurement of Deflections of the Vertical

During the last few years, new developments in the field of geodetic astronomy have been sparsely published. This might be due to the fact that the determination of deflections of the vertical still

Feasibility study of multipoint based laser alignment system for CLIC

CLIC (Compact LInear Collider) is a study for a future electron-positron collider that would allow physicists to explore a new energy region beyond the capabilities of today’s particle accelerators.

Impedance-driven coherent beam instabilities are usually studied analytically with the linearised Vlasov equation, ending up with an eigenvalue system to solve. The eigenvalues describe the

DEVELOPMENT AND VALIDATION OF A MULTIPOINT BASED LASER ALIGNMENT SYSTEM FOR CLIC

Alignment is one of the major challenges within CLIC study, since all accelerator components have to be aligned with accuracy up to 10 μm over sliding windows of 200 m. So far, the straight line
