The CubeSat (nano-satellite) is a light satellite that is small and robust, and used primarily to gather and transmit data. It is defined by the weight class of 1kg – 10kgs, utilised in various industries with the advantage of being significantly cheaper than a heavier craft. Unlike larger satellites, the CubeSat’s small size facilitates frequent inexpensive prototyping for future innovation, and improves the capability for the satellite to target specific problems because of the cost reduction in development and launch.

To decode, the bit stream should be NRZS decoded, then descrambled (G3RUH), then bit stuffing removed as per the AX.25 protocol. A summary of these can be found in: Communications Infrastructure for the MOST Microsatellite Project (Laura Halliday 2000).
The table below contains the satellite data (mostly sensor readings) in order. The decode method refers to functions given in the python script below to demonstrate the scaling used for each field.
Recent update: To see how the sensors readings are interpreted, see the code at https://melbournespace.com.au/static/sensors.py
