The first part of the article presents the advanced requirements regarding the FOS principle of operation, as well as the measurement method using a closed-loop operation. The closed-loop control algorithm is developed using the high-level language C++ and then it is synthesised into an FPGA. The following part of the article describes the simulation environment developed to test the operation of the control algorithm. The environment includes a model of components of the measurement system, delays, and distortions in the signal processing path, and some of the measurement system surroundings. The article ends with a comparison of simulation data with measurements. The obtained results are consistent and prove correctness of the methodology adopted by the authors.}, type={Article}, title={Firmware development for the fibre-optic seismometer based on FOG}, URL={http://www.journals.pan.pl/Content/130996/PDF/OPELRE_2024_32_2_M_Kotas.pdf}, doi={10.24425/opelre.2024.150179}, keywords={fibre-optic rotational seismometer, Sagnac effect, simulation environment, field-programmable gate array, high-level synthesis}, }
