前不久,美国Rockwell公司与中国华诚集团华诚卫通导航通信技术公司在国内首次举办了GPS技术应用研讨会,介绍了目前国际上GPS技术的发展现状、产品应用情况.华诚卫通公司还介绍了GPS产品在中国的开发应用情况,受到与会者好评.众所周知,美国Rockwell公司是国际知名的大型综合电子产品公司,年营业额达200亿美元.该公司研制生产的导航卫星及GPS产品已为美国军事部门广泛采用.海湾战争后,GPS技术在民用领域也掀起了应用热潮.由于来自美国商界的呼声不断高涨,美国政府迫于压力,同意将该系统先向民间免费开放10年.由于这一政策的首先得益者是发达国家,主要是美国本身,所以估计这一做法会继续延续下去.当然,美国政府在使用上采取了SA政策,即对民间开放的信息中加入了一定的干扰,以降低定位精度,但科学界又推出了如差分校正等技术,用技术的进步来抵销上述干扰.
Not long ago, the United States Rockwell and China Huacheng Group Huacheng Satcom navigation and communication technology company for the first time held a GPS application seminar in China, introduced the current international development status of GPS technology, product applications. Huacheng Satcom Also introduced the development and application of GPS products in China by the participants praise.As we all know, the United States Rockwell is internationally renowned large-scale integrated electronic products company with an annual turnover of 200 billion US dollars.The company developed and produced navigation satellite and GPS products Has been widely adopted by the U.S. military department.GPS technology has also brought a boom in the civil field after the Gulf War and the U.S. government was under pressure to agree to open the system for free to the public for 10 years due to rising calls from the U.S. business community. Since the first beneficiary of this policy is the developed countries, mainly the United States, it is estimated that this practice will continue. Of course, the U.S. government has adopted the SA policy in its use of certain information that is open to the public Of the interference to reduce the positioning accuracy, but the scientific community has introduced such as differential correction and other technologies to offset the progress of technology Said interference.
