长期等待的美国政府有关民间采用GPS的政策声明已向人们作出担保,允许向直接用户连续、全球、免费提供GPS服务。美国还将在未来的4～10年内停止故意降低民用GPS信号的工作,以便使商用接收机的精度从100米提高到20米。
The long-awaited US government policy statement on private use of GPS has made it a guarantee to allow continuous, global and free GPS services to direct users. The United States will also stop intentionally reducing civilian GPS signals in the next 4 to 10 years in order to increase the accuracy of commercial receivers from 100 meters to 20 meters.
