Résumé

—This paper 1 examines five strategies for upset protection in Gold sequence generators used to maintain signal acquisition in GPS receivers. This work is motivated by the increased prevalence of single-event upsets in ultra low-power GPS receivers. If any upset occurs in the Linear Feedback Shift Register (LFSR) modules, then the corresponding satellite signal must be re-acquired, resulting in high energy expenditure and time delay. We evaluate the performance and complexity of methods based on error correction and modular redundancy.
