随着空间信息技术与电子技术的迅速发展,GPS接收机越来越多地应用到国民经济建设和测绘生产中。GPS接收机性能的好坏以及准确度水平能否满足工作要求是评价其质量高低的关键。按照我国相关法律法规,GPS接收机应当按周期进行全面的校准测试,检测其性能和准确度能否达到测量要求。在校准测试过程中,我们遇到了各种各样的情况,结合实际,对规范中存在的一些不足之处进行说明,并提出建议。
With the rapid development of space information technology and electronic technology, GPS receivers are increasingly used in national economic construction and surveying and mapping production. GPS receiver performance is good or bad as well as the accuracy level can meet the job requirements is to evaluate the quality of the key. According to China’s relevant laws and regulations, GPS receivers should conduct a comprehensive calibration test cycle, testing its performance and accuracy can meet the measurement requirements. During the calibration test, we encountered a variety of situations, combined with the actual situation, some of the deficiencies in the specification to explain and make recommendations.
