On September 29, a one-day excursion to both the Tracking and Imaging RAdar and the Radio Telescope Effelsberg is arranged!
TIRA is the title of the first presentation at the one-day tour. The space observation radar TIRA (Tracking and Imaging Radar) on Wachtberg is not only the largest experimental system at Frauenhofer-FHR, it is also unique in Europe. As the name implies, the TIRA system comprises a tracking radar and an imaging radar. Moreover, the system holds several world records. Space agencies from all over the world use the special capabilities of the Fraunhofer scientists and their system for space missions. The system is used to gain precise measurements of space debris, prevent evasive maneuvers for operative satellites or create an image of an object that has gone out of control. This includes technical faults or the uncontrolled re-entry of satellites into the Earth’s atmosphere. The presentation will cover the technical limits and a brief history of the TIRA along with its various applications.
After the presentation, a guided tour to the parabolic dish is planed. If needed conditions for a demonstration are available, TIRA can be observed during its operation time.
An introductory talk at the visitors‘ pavilion of the Effelsberg Radio Observatory will cover some technical properties of the 100m radio telescope including its surface accuracy which enables observations to a limiting frequency of 96 GHz corresponding to 3.5 mm wavelength and also the different modes of radioastronomical observations performed with the telescope. These include spectroscopy with high frequency resolution, observations of pulsar signals at high timing resolution and broadband observations in order to map extended portions of the sky, derive radio fluxes and magnetic field structure via polarized radio emission. An additional observing method (Very Long Baseline Interferometry, VLBI) combines a number of radio telescopes around the Earth in order to improve spatial resolution. Space VLBI extends such virtual radio telescopes even beyond the size of the Earth. A second radio telescope at Effelsberg, LOFAR, enables radio observations at metre wavelength within a European framework of connected field stations.
The second part of the program at Effelsberg includes a guided tour to different stations, starting at the visitors’ pavilion: viewing spot directly in front of the 100m dish, Effelsberg LOFAR station consisting of a number of antennas for observations between 25 and 240 MHz, and the observatory building with the main control room for the 100m radio telescope.
You need to register for this tour on EDAS. Since both the transportation and the attendance are limited, the principle of ‘first come, first served’ is applied. This tour is highly recommended to all attendees of the WiSEE.
