LQSat is a micro-satellite with a volume of 40x40x60 cm3 and a mass of about 50 kg. The UHF quadrature feed turnstile antenna and the S-band patch antenna are mounted on +Y surface of the satellite. The satellite uses 3-axis stabilization, with its +Y surface facing the earth. The power system uses 5 Li-ion cells which are recharged by solar power provided by solar cells on each face of the satellite. Attitude determination and control subsystem is done by magnetometer, gyroscope, GPS receiver, sun sensor, star sensor, flywheels and magnetorquers.
