It has the following engineering objectives: on-board computers will be tested in harsh space environment as a form of competition to see which will last longer; technologies to receive and decode very weak and low bit-rate signals coming from deep space will be tested; and, technologies to estimate the Doppler shift on the satellite based on the received RF signal will be tested.
