Welcome to this sunny website showing a solar 10 GHz monitor |
|
| Our Sun from NASA's MDI; 2012/05/08 |
Brief intro to the
system 10 GHz receiver with 70 cm diameter dish and very low noise LNB, NF 0,3 dB. The converted signal is amplified for compensation of cable losses, appr. 7 dB at 2.4 GHz and measured by an HP powermeter. This power meter feeds an A to D converter for further processing by the Radio-SkyPipe program. Additionally this program produces the FTP transmission to the website. Tracking of the sun is achieved by a combination of the antenna rotor and the accompanying software from Orbitron. From now on the dish is permanently active. The .5° resolution of the rotator along with the 3° degrees (-3 dB points) beam width of the dish turns out too be a good combination. NB.: the sun's virtual diameter is approximately 0,53 degrees. Update of the graphics presentation SkyPipe every 5 minutes. Close to a real time presentation. |
