Summer 2009 tune to 437.505 MHz to hear Explorer -1 [PRIME] exploring the Van Allen radiation belts.
E1P radio communications happen on amateur radio frequencies. Because of the limited range of most* radio communications the amateur bands are regulated (or not, as the case may be) by individual countries. The national regulating agencies (eg FCC in the US) make the frequency allocation rules and amateurs share their bands by switching frequencies if a particular wavelength is over subscribed.
This same process must happen at the international level for amateur satellites. However, because satellite communications must be carefully planned well in advance, the cooperation must happen well in advance. Cooperation between hundreds of developers around the world is made complicated by time and space separation as well as the vagaries of development and launch schedules. By common agreement this mess is sorted by the
International Amateur Radio Union for which we are all eternally grateful.
Coordination is not easy, nor should it be. One must prove to the committee by providing details of your satellite plans and operation modes that your satellite has a chance at operational space flight and that it is truly an amateur project.
Friday the E1P team received the
final confirmation of coordination for the upcoming NASA ElaNa launch! This summer tune to 437.505 MHz to hear Explorer -1 [PRIME] exploring the Van Allen radiation belts.
*Some of the most interesting amateur radio happens at wavelengths longer than 8 meters where the ionosphere is reflective. This mirroring effect allows radio waves to travel for thousands of miles, sometimes to the other side of the planet! In reality the lack of global regulation has more to do with the limited range of politicians.
