[2011-10-04]The metallic reflecting grid in Dourbes
The 8m x 8m metallic grid has been installed in Dourbes. Very nice job from our engineering staff. Now we try to analyze the influence of this change of the radiation pattern on the number of plane echoes, their intensity and on the intensity of the carrier.

Thank you to Francesco Lo Bue and Peter Meurisse for hosting the station at the University of Mons and helping us to install the material.

[2011-08-09]The metallic reflector grid for the beacon in Dourbes is under construction
Our engineering team in the workshop has now started building a 8m x 8m metallic grid which will strongly improve the radiation pattern of the beacon antenna. Currently too much power is emitted at small elevation angle resulting in a very intense carrier signal and a lot of strong plane echoes. With this grid, the situation will improve a lot (see tests in the news from 07/06/2011). Below are two pics of one 2m x 2m block of the future metallic grid. The picture on the right is a picture from above.

[2011-07-07]BRAMS in the newspaper(s)
Following a press conference held at the Euro Space Center, several newspapers were interested to ask me questions about BRAMS. The first paper was published 2 days ago by Le Soir :
"Ecouter" les étoiles filantes
Another one will be published soon (August?) in La Libre Belgique.
[2011-07-04]Station nearly ready in Neuchateau
The receiving station is nearly ready in Neuchateau. Only the PC must be installed and configured. The first tests will be done in about 2 weeks. Below is a picture of the antenna and of the nice installations of the OCA (Observatoire Centre Ardennes).

[2011-06-07]Solar flare visible in BRAMS data
This morning, an M2.5 solar flare peaked at 06:30 UT. It was visible on BRAMS data. Thanks to Felix Verbelen for sending us this picture.
[2011-06-07]Test of the beacon in Dourbes : more data from various stations
[2011-05-17]Test of the beacon in Dourbes
Last thursday (12/05), we made some tests with the beacon in Dourbes to simulate a metallic reflector of size 6m x 6m and 8m x 8m (using aluminium sheet of papers).
- The beacon was shut down at 12h15 local time (10h15 UT). First image below shows data before the shutdown.
- The test with the 8m x 8m "grid" was made from 15h15 (13h15 UT) to 15h45 (13h45UT). See second image below.
- The test with the 6m x 6m "grid" was made from 15h52 (13h52 UT) to 16h00 (14h00UT). See third image below.
The spectrograms clearly show that the direct signal is strongly attenuated (although still visible) and the number of reflections on planes has also strongly decreased. The intensity of the plane echoes is also strongly reduced.
