GNSS 수신기의 성능, 예를 들어 TTFF (time to first fix) 및 위치 정확도 등을 특성화하기 위해 여러 표준 테스트를 사용할 수 있습니다. 테스트 실행에는 종종 일련의 테스트가 포함되며, 각 테스트마다 서로 다른 시나리오가 있습니다. 따라서 사용자가 다양한 시나리오를 시뮬레이션할 수 있게 하는 위성 시뮬레이터가 이러한 목적에 이상적입니다.
R&S의 SMBV100A를 위한 GNSS 솔루션은 유연성이 뛰어나다는 특징이 있습니다: 하이브리드 GPS, Glonass, Galileo, BeiDou 및 QZSS/SBAS 별자리를 포함하여 최대 24개의 위성과 함께 복잡한 시나리오를 무제한 생성 할 수 있는데, 이 모든 것이 몇 가지 키 입력만으로 가능합니다. 사용자는 앨머넥(almanac) 파일 뿐만 아니라 지리적 위치를 선택할 수 있으며, 사용자 지정 경로를 따라 수신기의 움직임을 시뮬레이션하는 고정 위치와 이동 시나리오가 모두 가능합니다. 제한된 위성 시야의 조건을 시뮬레이션 하기 위해 개별 위성의 신호 강도를 실시간으로 제어할 수 있습니다.
SMBV100A가 제공하는 GNSS 기능에는 다중 경로 신호 생성, 건물 및 교량으로 다양한 대기 효과 및 주변 환경을 모델링 하거나 현실적인 차량 동역학을 시뮬레이션하여 사실적인 전송 및 신호 수신 조건을
시뮬레이션할 수 있는 기능이 포함되어 있습니다.
SMBV100A의 다양성은 단일 장비로 다양한 기능을 테스트할 수 있으므로, GNSS 모듈을 제품에 통합 한 휴대 전화 및 자동차 인포테인먼트 시스템 제조업체에 특히 유용합니다.
SMBV100A의 글로벌 항법 위성 시스템 (GNSS) 솔루션은 R&D 연구소에서든 생산 현장에서든 위성 시뮬레이션 분야에서 새로운 표준을 제시합니다.
정적 위성을 이용한 간단한 설정에서부터 최대 24 개의 다이나믹 GPS, Glonass, Galileo, BeiDou 및 QZSS/SBAS 인공위성으로 실시간으로 생성되는 유연한 시나리오에 이르기까지 모든 시나리오를 지원합니다.
