GB/T 18214.1-2000 in English

《GB/T 18214.1-2000全球导航卫星系统（GNSS） 第1部分:全球定位系统（GPS） 接收设备性能标准、测试方法和要求的测试结果》由TC43（全国导航设备标准化技术委员会）归口，主管部门为工业和信息化部（电子）。
本标准根据IMO决议A.819（19），规定了船用GPS接受设备最低性能标准、测试方法和要求的测试结果。该设备是利用美国联邦政府国防部（US DOD）的全球定位系统（GPS）信号进行定位的。在选择可用性（SA）有效的情况下，定义了GPS标准定位服务（SPS）的信号规范（美国国防部于1993年12月公布的GPS信号规范中，已对GPS SPS进行了说明）。本标准也适用于IMO决议A.529（13）中规定的其他水上航行用的GPS接受设备。

Scope

According to IMO resolution A.819 (19), this standard specifies the minimum performance standards, test methods and required test results for marine GPS receiving equipment. The device is located using Global Positioning System (GPS) signals from the United States Department of Defense (US DOD). In the case where Selective Availability (SA) is valid, the signal specification of GPS Standard Positioning Service (SPS) is defined (GPS SPS has been described in the GPS signal specification published by the US Department of Defense in December 1993). GPS SPS minimum performance standards are summarized in Table 2. This standard is also applicable to other GPS receiving equipment for water navigation specified in IMO Resolution A.529 (13). All sentences in this standard that are equivalent to IMO resolution A.819 (19) are marked with the chapter number in brackets. The requirements of Chapter 4 and Chapter 5 correspond to each other.
