提出了一种新的算法，在由于时间信号阻塞而导致可用卫星不足三颗的情况下，能够以可接受的精度进行 GPS 定位。实际数据测试表明，所提出的算法通过提供适合时间不足条件下超过一分钟的导航应用的定位结果，显着提高了 GPS 可用性。该算法不需要额外的传感器或数字地图的支持，同时增加的系统总成本可以忽略不计。
A new algorithm is proposed to enable GPS positioning with acceptable accuracy based on less-than-three available satellites in insufficient condition caused by temporal signal blockage. Tests in real data demonstrate that the proposed algorithm offers significant improvement of GPS availability by providing location results suitable for navigation applications in temporal insufficient condition more than one minute. The algorithm does not need extra sensors or support of digital maps, meanwhile the increased gross system cost is neglectable.
