Fiber-Optic Temperature Sensors for Monitoring the Influence of the Space Environment on Nanosatellites: A Review

This research investigates the development and integration of fiber-optic temperature sensors (FOTS) into nanosatellite systems for enhanced temperature monitoring in space environments. Utilizing mathematical models, calibration tests, and integration strategies, the feasibility and effectiveness of deploying FOTS in nanosatellites have been demonstrated. Calibration tests conducted in simulated space environments validated the accuracy of FOTS readings within the specified temperature range of −30 ℃ to + 60 ℃. Integration strategies, guided by mathematical models, facilitated seamless incorporation of FOTS into a 3U nanosatellite platform, addressing challenges related to space constraints and power consumption. Implementation of low-power data acquisition systems further optimized energy efficiency while ensuring continuous operation of FOTS. The research findings underscore the importance of FOTS in enhancing temperature monitoring capabilities in nanosatellite missions, contributing to improved reliability, performance, and longevity of space systems. Prospects for further research include enhancing sensor performance, exploring multi-sensor integration, validating space qualification, adapting to diverse mission requirements, and integrating with autonomous systems. Overall, this research advances the field of space sensor technology, paving the way for more robust and capable nanosatellite systems in future space exploration endeavors.
