P3E

P3E (AMSAT-Phase 3E)

P3E LogoThe AMSAT-Phase 3E satellite (P3E) is dedicated as communication and scientific platform for a highly elliptical orbit around Earth. The spacecraft will be created in a joint process together with the P5A Mars mission by an international team under leadership of AMSAT-DL and continues the successful series of AMSAT-Phase 3 satellites. Additionally the spacecraft will be a test bench for technology developped for the Mars mission. The main task of P3E is to act as communication platform for radio amateurs worldwide. A launch isn’t planned we are waiting for an opportunity.

Mission

P3E ModelAs a communications satellite, P3E will carry several transponders useful to radio amateurs and having bandwidths between 50 and 200 KHz. The emphasis will lie on the lower VHF/UHF frequencies between 145 and 2400 MHz. That simplifies the free world-wide radio operation independent of the propagation variability of short-wave and away from the anonymity of Internet chats. Due to the efficient HELAPS transmitter technology and a newly developed, software-defined transponder (SDX/STELLA), radio operation will also be possible for small and portable stations. The software technology will also enable flexible digital transmission methods. For microwave experiments, P3E includes additional beacons and transponders.
