Multispectral Earth Imaging Satellite (MEISAT) is SaTReCi’s 100 kg micro satellite which will be adequate to support a high resolution multispectral Earth imaging camera. MEISAT, whose development is currently in progress, is capable of achieving a ground resolution of 8.5 meters with a 47 km swath width and 400 km scan length from its intended orbit of 730 km. The low-cost satellite is also capable of storing 8 Gbits of image data which will be transmitted to ground at 10 Mbps with an X-band transmitter. This paper provides an overview of MEISAT mission operation concept. The mission requirements and the system specifications are also discussed. The paper then describes the overall system configuration. The design of the command and data handling system, the power system, the attitude control system, the RF system, and the payload system is presented
