CubeSat is a type of miniaturized satellite with at least 10x10x10 cm in cubic units for its volume and has less than 1.33 kg per unit for its mass based on the CubeSat standard. Currently, CubeSat technology is mostly used for earth observation purposes. In this paper, a CO2 Detection payload for the CubeSat was proposed, it is expected to be able to detect the CO2 concentrations from 400 km of altitude. CO2 is one of the greenhouse gasses emitted by human activities or by natural produces, CO2 molecules can absorb infrared radiation and trap some energy from it in the atmosphere which can trigger global warming, therefore it is important to be observed. To achieve the mission, an InGaAs Photodiode sensor will be used in this payload. This sensor will measure the power of infrared radiance in the atmosphere, and the final output from this payload module is an analog signal in voltage magnitude. By measuring this parameter which is the power of infrared radiance in the atmosphere, it is expected for the payload to be able to estimate the CO2 concentrations. This paper will also show the performance of the integrated amplifier circuit to amplify the produced signal from the InGaAs Photodiode sensor since this sensor will produce an analog signal in a very small magnitude.
