Preliminary observations at 10-cm wavelength using the NRL 84-foot radio telescope

Local Survey at the E elsberg Radio Telescope 1997 - Preliminary

In summer 1996 a major repair of the EEelsberg 100 m radio telescope's ground track had to be carried out due to cracks in the tracks surface. This led to a signiicant permanent displacement of the VLBI reference point. A local survey was, therefore, organized to measure the position of the reference point with respect to three permanent ground markers which had also been used in earlier measur...

Design Studies for 440-Foot-Diameter Radio and Radar Telescope

Studies conducted by the Cambridge Radio Observatory Committee during the past two years show that a large steerable telescope can be constructed at lower cost and with higher precision if the antenna is protected from the environment by a radome. These studies also indicate that the extremely high pointing precision (10 arc-sec) needed to make effective use of a large aperture at wavelengths a...

Observations of the bright radio sources in the North Celestial Pole region at the RATAN-600 radio telescope

Abstract. A survey of the North Celestial Pole region using the RATAN-600 radio telescope at five frequencies in the range 2.3 to 21.7 GHz is described. Sources were chosen from the NVSS catalogue. The flux densities of 171 sources in the Declination range +75◦ to +88◦ are presented; typical flux density errors are 5-10 percent including calibration errors. About 20 percent of the sources have ...

Using the Web to Plan Telescope Observations

The new generation of large, ground-based telescopes must operate differently than previous telescopes. The cost of developing and operating these telescopes means that efficient and effective operation has a high priority. While classical observing often means that astronomers work out the details and sequencing of observations while seated in front of the telescopes; the new telescopes requir...
