dc.description.abstract	For this Bachelor’s thesis, a compact and independent system for performing tunable laser diode spectroscopy in a CubeSat nanosatellite has been designed. The system is modulated in alternating current and works tuning a vertical-cavity surface-emitting laser and using both electromagnetic absorption and dispersion for the purpose of measuring on the device under test, which would be a gas cell or a fiber sensor. Specific design principles were applied to this project, namely, power efficiency, compliance with the ROHS rules, optimization of its size, COTS usage, AC modulation, single supply as well as the CubeSat specifications. This thesis is under the umbrella of the NANOSTAR Project. The system designed can be tuned within a range of 9 nm and automatically calibrate its emission wavelength through the usage of an HCN reference cell. It is able to perform a full-range sweep or tune specific wavelengths for a fast measurement. This project includes the characterization, design and simulation of the system composed by photonic, electronic and optoelectronic components. Its implementation includes the design and assembly of a prototype as well as its control software and resolution and error calculations. The prototype is completely autonomous and only requires a DC power supply in order to recharge its batteries as well as communication with its controller board.	es
