News & Events

On February 25 and 26 2020 we participated as expositors to the Paris Space Week 2020, the trade show with business meetings dedicated to the space industry. In these 2 days, 1000 participants were able to visit our booth where we presented all our latest products for satellite communication and radio astronomy. There was a lot of interest about our complete radio telescopes and our affordable antenna tracking systems!

In fact, during the Paris Space Week 2020, we had a large focus on our antenna tracking systems that provide an affordable way to precisely move also very large antennas also in harsh environment. We also showed our H142-One radio astronomy receiver for 1420 MHz radio astronomy together with our RadioUniversePRO control softwares for radio telescopes.

Paris Space Week 2020 took place at the National Air and Space Museum of France in Paris – Le Bourget airport where we admired many historical spacecraft and we were amazed by the huge Ariane 5 launchers that seemed ready for takeoff!

Radio2Space team visited the Effelsberg radio telescope in Germany that, thanks to its 100 meters diameter parabolic antenna, it’s one of the largest fully steerable radio telescopes in the world! Operated by the Max Planck Institute for Radio Astronomy in Bonn, the Effelsberg radio telescope is situated in North Rhine-Westphalia. Today it’s now one of the most advanced radio telescopes worldwide.

Dr. Norbert Junkes (Press and Public Outreach, Max-Planck-Institut für Radioastronomie) showed us the radio telescope in detail bringing us with a lift at 50 meters from the ground, just under the big antenna. Since the Effelsberg radio telescope operates from 350 MHz up to 86 GHz, the antenna has been designed to keep a very precise parabolic shape also with the deformation of the antenna due to gravity when it’s rotated in different directions.

At a lower level, 4 huge motors are in charge to move the elevation axis. The Effelsberg radio telescope is fully steering and this means that the 100 meters antenna can be moved 360 degrees in azimuth and 90 degrees in elevation, allowing the radio telescope to be pointed in any direction and down to the horizon. The azimuth movement is performed by rotating the entire structure (the time for a rotation of 360◦ is 15 minutes) that weights 3200 tons!

In front of the Effelsberg radio telescope there is the institute with the control room directly facing the antenna. From here researches control the radio telescope, with 8 screens in the main control room that allow them to have in real time all the scientific data. We were happy to see that, also if this is state of the art professional radio astronomy software, our RadioUniversePRO for SPIDER radio telescopes has some features in common!

Before visiting the Effelsberg radio telescope, we tried to imagine its incredible size, comparing it with other radio telescopes we had already visited. But now, by having a first person view of it, we’re even more impressed by the dimensions and the precision of this amazing radio astronomy instrument that is operational by 50 years but that looks like new. Thank you to the Effelsberg radio telescope team to let us visit this incredible instrument.

Radio2Space team completed the installation of a new SPIDER 500A radio telescope in Sharjah Center for Astronomy & Space Sciences, close to Dubai in the United Arabic Emirates and now it’s time for the first light. SPIDER 500A is a 5 meter radio telescope that, thanks to the large antenna and the specifically designed radio astronomy receiver, offers a very high sensitivity. We decided to capture data from Orion A, the Orion Nebula (M42) that emits also radio waves at the 1420 MHz frequency (flux 490 Jy) recorded by the radio telescope.

Orion A mapped with the SPIDER 500A radio telescope in Sharjah: the SPIDER 500A radio telescope used to map Orion A.

Orion A (also known in astronomy as M42) is 1,500 light years from Earth and it shines because it is heated by ultraviolet radiation from young stars called ‘Trapezium’ at the center of the nebula itself. These stars heat the surrounding gas generating radio waves.

The SPIDER 500A radio telescope in Sharjah Center for Astronomy & Space Sciences is controlled from a control room near the radio telescope. Here the H142-One receiver is installed, together with the antenna control and power unit, and everything is connected to a computer running the RadioUniversePRO software to control the radio telescope, capture and process data. In the early afternoon, Radio2Space team together with Professor Ilias Fernini (SCASS Professor of Physics and Astronomy) and Issam S. Abujami (SCASS IT & System Specialist) aligned the radio telescope to the sky and pointed Orion A.

RadioUniversePRO software allows to precisely define all the parameters requested for an automated radiomap acquisition like the map dimension in degrees, the resolution and the integration time for every pixel. For this first light it was chosen to record a 5×5° map with 0,7° resolution and 30 seconds integration for every pixel. After around 1.5 hours, the radio map appeared on the screen, highlighting Orion A with the peak of emission of the Orion Nebula at 1420 MHz. By using the proper feature of RadioUniversePRO we also selected to create the contour level lines that have been overlayered to the map that you can see in the picture below.

This Orion A map is a great result for the SPIDER 500A radio telescope installed in Sharjah Center for Astronomy & Space Sciences and it confirms the high sensitivity of the entire system that allows everyone to make real radio astronomy with a complete and easy to use radio telescope. Radio2Space team with Professor Ilias Fernini and Issam S. Abujami decided to take a group picture, with the result of this great first light!
