| Summary: | 碩士 === 國立臺灣科技大學 === 機械工程系 === 100 === Today, the growing popularity of global positioning system (GPS) application has become more and more attractive topic for both scientific and navigation experiment onboard a small satellite project. Due to space qualified GPS receiver is always beyond economic budget constrain. Therefore, how to utilize the current stock of commercial grade components (Commercial-Off-The-Shelf, COTS) to going through a series of space level of the environmental testing and screening procedure(s), is considered a practical approach under a reasonable cost.
Especially space ionizing radiation environment is the most different between normal ambient application case. Therefore, the Total Ionizing Dose(TID) will be conducted and analyzed to evaluate the space application potential or capability of general commercial GPS component.
For the above reasons, this study will understand the space environment conditions and associated effect on semi-conduct electronic component first, then reference the MIL-STD-883G, Method 1019.4, to conduct a different GPS Radio Frequency Front End component under different level of Total Ionizing Dose(TID) exposure with different shield effect tests, in order to verify its performance、reliability and survival in a radiation environment condition.
