成果简介	NOVELTY - The on-board system has a quartz resonator-based sensor module (1) and an analytical module (2) located inside the satellite body. An STM32 microcontroller in the analytical module is connected to the satellite's on-board computer through a controller area network (CAN) interface. The on-board system has a read-only memory device and a real-time clock. A programmable logic integrated circuit (PLIC) used as part of the analytical module is connected to the STM32 microcontroller through the SPI interface. USE - On-board system for monitoring contamination phenomena inside instruments of CubeSat satellite. ADVANTAGE - The device allows for monitoring the growth of thin films of sublimated substances on the internal surfaces of space instruments. The high clock frequency of the field programmable gate array (FPGA) ensures measurements with high accuracy, thus avoiding delays and errors inherent in microcontrollers that use interrupts to process signals. The FPGA in parallel processing mode measures the frequencies of two generators, while the process of measuring one generator does not affect the measurement of the other, which increases the stability and accuracy of each measurement. The built-in PLL system minimizes phase errors, thus improving the accuracy of frequency determination and reducing the accumulation of errors. The measurement results are transmitted to the microcontroller through the SPI interface, which ensures fast and stable data transfer. It is proposed to use the CAN interface to connect the microcontroller to the onboard computer. The measured data are stored in a permanent memory device, which increases the system's stability in the event of communication failures with the satellite and guarantees reliable storage of information. The measurement error us reduced to ± 1 Hz when determining the frequency of signals from the measuring and reference generators in the quartz resonator operating range from 6 to 8 MHz, which allows for increased accuracy in measuring the thickness of the contaminant layer formed on the surface of CubeSat satellite devices over a given time interval.
