What is EquiSat?
EquiSat is a low-cost CubeSat constructed in a short time frame by a small group of undergraduate engineering students to encourage non-professional involvement in the ever-growing aerospace industry.
As such, a key objective of the EquiSat is accessibility to the public eye. The satellite's main payload is an optical beacon that will emit enough light to be visible on earth by the naked eye. Equisat will also transmit a radio signal that can be read by anyone via amateur radio.
What is CubeSat?
According to Wikipedia:
A CubeSat is a type of miniaturized satellite for space research that usually has a volume of exactly one liter (10 cm cube), has a mass of no more than 1.33 kilograms, and typically uses commercial off-the-shelf electronics components. Beginning in 1999, California Polytechnic State University (Cal Poly) and Stanford University developed the CubeSat specifications to help universities worldwide to perform space science and exploration.
