The new technology demonstration microsatellite was designed based on proven Microsatellite platforms, which were composed by two parts: microsatellite platform and payload cabin. The microsatellite uses body mounted solar cell, and the payload cabin includes 8 standard PODs with volume of 4U for each. For each POD, it could carry a 3U CubeSat and the rest 1U is for release mechanism. The whole Microsatellite can load eight 3U CubeSats or electronic units which taking “U” as a basic unit.

Payload

1.

Size

Whole  satellite envelope

600mm×570mm×750mm；

We  suggest taking “U” as the basic unit for the payload, since the loading space  can be 3U*8=24U. If the payload is bigger than 3U, the loading space could be  changed up to 450*450*450mm by removing all PODs.


2.

Mass

About  50kg约50kg

About  30kg

3.

Power consumption  and voltage

Compatible  with 12V, 28V (it can be adjusted according to other requirements)

Long-term  power consumption: 35W

If  the payload needs larger peak power consumption, the battery capacity can be  adjusted in advance.

Totally  of about 20 W (if a higher power is needed, the double side panels can be  added. The whole satellite power could reach 100W, while the payload power  can be 70 W).

Payload  processing function could be provided by OBC. It can be adjusted according to  the requirements.

4.

Attitude control

Basic  (magnetic control) ≤1º

Enhanced  (flywheel) ≤0.1º

5.

Transfer rate

≥1Mbps

6.

Data  Downlink

10~100Mbps

7.

Information  interface

422;  485; 232; CAN, 1553 b, IIC or other  interfaces can be adjusted according to the requirements.

8.

Attitude  Stability

≤0.001°/s~0.05°/s（3σ）
