초록

오늘날 민간에서 사용 중인 측위 시스템의 대부분은 위성의 신호를 수신하여 현재 위치를 계산하는 글로벌 위성항법 시스템(GNSS; Global Navigation Satellite System)을 기반으로 한다. 미국이 GPS (Global Positioning System)를 통하여 입증한 GNSS의 효용성은 다양한 국가에서 위성항법 시스템을 구축하고 고도화 하도록 이끌었다. 그중 중국은 앞선 IT 기술력과 자금력을 바탕으로 자체 GNSS인 베이더우 위성항법 시스템(BDS; BeiDou Navigation Satellite System)의 급진적인 개발을 성공시켰다. 중국이 빠르게 전 세계로 BDS의 서비스 영역을 확대하고 있는 것을 고려할 때 우리나라에서도 BDS에 대한 체계적인 연구가 요구된다. 따라서 본 논문에서는 BDS의 공개 신호인 B1C에 대한 전반적인 정보를 제공하여 B1C 신호 체계 설계 및 BDS B1C 수신기 설계에 활용될 수 있도록 한다.

Most civilian positioning systems in use are based on the Global Navigation Satellite System (GNSS), which receives signals from satellites and calculates the current location. After the successful establishment of GPS from the U.S., GNSS has led to promote satellite navigation systems in various countries. Recently, China has succeeded in the radical development of its own GNSS, the BeiDou Navigation Satellite System (BDS), based on its advanced IT technology and funding power. Considering that China is rapidly expanding the service area of BDS to the world, systematic research on BDS is also required in Korea. Therefore, this paper provides overall information on B1C, the open signal of BDS, so that this information can be utilized in the design of B1C signal system and BDS B1C receiver design.
