  • 국제표준화기구(ISO)에서는 장비에 대한 표준화작업을 ISO/TC172에서 관리하고 있으며 산하의 전문위원회인 SC6에 속해있는 ISO17123 $1{\sim}8$은 주로 측량장비의 정밀도를 참조할 때 인용되는 표준으로 그중에서 ISO17123-8: GNSS field measurement systems in real-time kinematic(RTK)은 GNSS의 RTK 정확도평가방법으로서 약식시험절차와 엄밀시험절차를 규정하고 있다. 본 연구에서는 ISO17123-8의 규격을 분석하고 이 규격에 따라 GPS RTK Test-bed를 시험구축하고 정확도 평가방법에 따라 관측값 Testing하는데 목적이 있다.

  • This paper has theoretically and practically reviewed the ISO (International Standard Organization) 17123-8 standard not only to raise the appropriateness for introducing performance criteria of GNSS (Global Navigation Satellite Systems) surveying equipment based on RTK (Real-Time Kinematic) accuracy but also to derive its proper test procedure by introducing the international standard. Field experiments have been performed to appreciate the GNSS-RTK accuracy of five selected receivers via the full testing procedure of the ISO standard, which statistically compares the so-called experimental standard deviations with themselves and with the reference accuracy. A series of statistical tests have revealed that the RTK accuracy of the same class receivers is not identical, whereas that of the different classes can be equivalent. Such a result evidences the urgency of adopting an RTK accuracy-based specification of the GNSS equipment to the performance standard, currently referenced to the static observation technique only. It is believed that this transition helps the maximization of a new generation of cost-effective receivers to legal surveying applications. Finally, this study proposes the ISO full test, comparing an experimental standard deviation with its referenced value, for a potential field verification procedure of the new performance standard.

  • 정밀한 관측을 요하는 측량장비의 기능을 보정하거나 검증하는 것은 측량시 매우 중요한 일이다. ISO17123-8 규격은 GNSS RTK 정확도를 결정 할 때 사용되는 야외실험 절차와 규정을 명시하고 있으며 정확도 평가방법으로는 약식시험절차와 엄밀시험절차를 제시하고 있다. 본 연구에서는 GNSS RTK 정확도 평가방법 중 엄밀시험절차에 대해 시험할 목적으로 GNSS RTK 규격에 따라 Test-bed를 구축하였고 성능실험을 실시 위하여 GNSS RTK 규격에 제시된 정확도 평가방법을 적용하였다.
