| Headline Details: A 1U cubesat. The main missions of KNACKSAT includes: (1) testing in-house developed subsystems in orbit (2) studying 3-axis attitude control using magnetic torques (3) testing in-house developed transmitter and receiver in orbit and (4) take picture of Earth by CMOS camera. The earth images will be shared through radio amateur networks. Another mission is message relay service for amateur radio community. Details of the service will be determined. The on-board subsystem is the in-house developed by engineering students. After satellite launched in the orbit, KNACKSAT attitude control system is active controlled by three axis magnetic torquers. The attitude determination uncertainty will be less than ±10 degree. The attitude determination will be done using sun sensors, magnetometers and rate-gyros. The communication subsystem is using in-house developed transmitter and receiver. The transmitter is able to work with GFSK modulation at 1200/9600 bps speed. The receiver is able to receive FSK at 1200 bps speed. KNACKSAT is carry a 5M pixel CMOS camera module onboard satellite and aim to capture images of the Earth. The image will be widely distributed and use for educational purpose. This mission has both research and outreach objectives. The image will be distributed to communication and space based Science, Technology, Engineering and Mathematics education (STEM program). Proposing a UHF downlink.

Planning a FY 2017 launch. **A downlink on 435.635MHz has been coordinated** | ||||
