It’s more than three years that I monitor VHF for meteor scatter signals thanks to the French GRAVES radar near Dijon. This is a bistatic radar that transmits a CW signal at 143.050. With a simple radio system is possible to receive the radar signal reflected by the meteors ionized plasma that these objects create […]

Tra qualche giorno la stazione spaziale cinese Tiangong-1 entrerà nell’atmosfera terrestre disintegrandosi, speriamo per gran parte della sua mole. Per l’occasione ho predisposto il mio sistema per la ricezione meteor-scatter VHF tramite il radar GRAVES, in modo da provare a ricevere un’eco radio prima della totale disintegrazione della stazione. In questo caso, visto che attualmente […] Here some of the best images from Orionids shower of this year and a time lapse video of the shower period: Friends link about this event: IU3IOU Giorgio IK0OZK Renato […] Questi giorni si avvicinerà alla Terra l’asteroide 2012 TC4 ad una distanza veramente minima per un oggetto spaziale, domani alle 7:42 ita il picco di massimo avvicinamento. Con quasi le stesse modalità del sistema meteor scatter sto provando a ricevere sulla frequenza del GRAVES l’eco dell’asteroide che transiterà a circa […] Solo ora sono riuscito a terminare la stesura del report sulle Perseidi 2017. Purtroppo ancora ho problemi nel far lavorare assieme SpectrumLab con RMob con la conseguenza che i dati degli eventi non si distribuiscono per ore ma sono raggruppati in grossi “ammassi”, solo grazie all’indispensabile e preziosissimo aiuto del mio amico e […] What follows is the capture of ISS (International Space Station) passing over my coordinates this morning. The fast descending signal is the trace of doppler echo from GRAVES signal. The yellow circle shows where the ISS was about during the capture and the red arrow the direction. […] A very big echo captured during this meteors shower event: Almost a 2 minutes long echo with a very strong reflection signal. The same signal was received from other GRAVES friends. Suddenly today at about 10:20 UTC no more echoes from GRAVES transmitter have been received at my meteor receiver. A Christmas time maintenance? Shortly before a strange activity has been captured from my receiver some Hz upper the usual meteor frequency. […] In these last days I focused my free time to meteors radar by French GRAVES VHF Radar transmitter. The new page is here: Meteors Radar. On this page you can find a 3 minutes auto-refresh picture almost real time. Just under a statistics image of received meteors signals. At the moment the system is composed by […] |
