克林顿政府最近计划在10年内停止降低GPS的精度,以便有时间来研制替代的方法来限制敌方军队利用GPS。消除GPS“粗/捕获”(C/A)信号的选择可用性(SA)误差是美国研究委员会(NRC)去年春天强烈建议的。由NRC一个专家组编写的这份报告呼吁支持GPS的未来研究,还建议用具体的替代技术来防止敌方使用GPS。报告还提出了对非军方用户的GPS增强方案。 The Clinton administration recently planned to stop reducing GPS accuracy within 10 years in order to allow time to develop alternative ways to limit the use of GPS by enemy forces. The choice of availability (SA) error to eliminate GPS “coarse / catch” (C / A) signals was strongly recommended by the National Research Council (NRC) last spring. The report, prepared by a group of NRC specialists, called for support for future research on GPS and also suggests that specific alternative technologies be used to prevent hostile use of GPS. The report also proposed GPS enhancements for non-military users.
