Demonstration of data relay system. Environmental measurements are acquired through ground sensors, collected, temporarily stored on the ground, and logged by an autonomous terminal until upload request is received from TEMISAT.Characteristics: (a) Mass 42 kg (b) Dimension 35 x 35 x 35 cm, (c) Electric power 62 W Max, (d) Attitude control : 2 magnetic coil, 1 Am**2, (e) On-board memories - 2 of 8.5 Mbytes each, (f) Lifetime 5 years. Drift of the ascending node of orbital plane: 0.8 deg/d westwards. Copassenger of METEOR 2 satellite.

Total Mass: 42 kg.
