Downlink: 145.965 - 145.935 MHz SSB/CW
Output Power: 33 dBm (2 W) @ - 105 dBm RX input
Shape and structure of the satellite:
The main body of the spacecraft is made by special aluminum,
three vortex triangle shaped, but this could not be the definitive
format; studies have been carried to determine a final shape
in order to optimize the physical structure and therefore maintain
a desirable amount of energy being delivered by these, to keep the
satellite in operational condition.
