AMSAT P3D (Phase 3D, AO 40, AMSAT-OSCAR 40)


AMSAT P3D (also known as Phase 3D, and as AMSAT-OSCAR 40) is an international amateur radio spacecraft built by AMSAT led by the german chapter AMSAT-DL. It was launched as an secondary payload on an Ariane-5G rocket from Kourou at 01:07 UT.

The 400 kg AMSAT P3D spacecraft is the largest amateur-support spacecraft, carrying 5 receivers (in the HF, VHF/UHF, L, S, and C bands) and seven transmitters (in the HF, K, VHF/UHF, S, and X-bands). Also carried on-board are some experimental instruments such as two cosmic ray monitors named TDE, and CPE, two wide-angle cameras in the SCOPE unit available for the amateurs to command their images from locations of interest, a passive ionospheric sounder to scan the 0.5 to 30.0 MHz band so as to derive the electron densities in the upper part of the ionosphere, and a GPS-receiver to locate the spacecraft position. 250 W electrical power is provided by solar cells charging batteries.
