In this paper, we have proposed a methodology which can make effective test for system integration of complex guided missile system. System integration test play a significant role in the development of weapon system, providing the means to detect and isolate faults on first linkage between sub-systems. Integration tests for domestic weapon system has executed not a technology-intensive method based on tool but labor-intensive method based on experience. Higher cost, longer period, and more resource are required to execute system integration test for complex guided missile system comparing with past weapon systems, because recently weapon systems have more complex and more networked functions. Because the proposed design method for system integration test decreases number of test case, it lead to a decrease of cost, period, and resource for integration test of weapon system. The proposed configuration for system integration test will ensure reliability through detection and isolation of fault on linkage between sub-systems.

According to the Korea Augmentation Satellite System (KASS) system milestone, Site Acceptance Test (SAT) has three steps test until the end of the project. SAT#1 is the first time of SAT steps and verify the KASS Reference Station (KRS) and Sub System (S/S) for the monitoring and controllable. After the equipment and software were installed at the Mission Control Center (MCC) with Central Monitoring and Control Simulator (CMS) for the SAT#1, the 1:1 test was progressed when the KRS and S/S are ready to test. SAT#1 has a 10 steps test case and it was progressed each KRS sites. The test was finished throughout the real-time monitoring and the data collection including the data analysis all of the 7 KRS sites. Finally SAT#1 was completed on December 2020 with successfully.

The GPS/INS integration system navigation can provide improved navigation performance and has been widely used as a main navigation system for military and commercial vehicles. When two navigation systems are tightly coupled and the structure is complicated, a fault in either the GPS or the INS can lead to a disastrous failure of the whole integration system. This paper proposes a real-time fault detection method for an AGPS/INS integration system. The proposed fault detection method comprises a BIT and a fault detection algorithm based on chi-square test. It is implemented by real-time software modules to apply the AGPS/INS integration system and van test is carried out to evaluate its performance.

Testing evaluation is a part of process for design, production, evaluation, operation and abolition, and is the process of certifying system performance. The main purpose of testing evaluation is to reduce the risk factor under the determining process. Testing process has the three step such as design qualification, integration and validation test in factory, system integration and commissioning test. Design Qualification is to verify errors on the design process. Integration and validation test in factory is for the H/W and S/W of an equipment and is to verify interface of subsystem, communication protocol and main functions. System integration and commissioning test is a functional test to adjust successful installation of equipment. According to the testing process, briefly consideration for test item, test method and test contents about signalling system is carried out.

최신항공기 개발에서 증가추세에 있는 항공전자 장비들의 효율적인 통합시험 수행을 위 해 통합시험환경구축이 중요한 역할을 하고 있다. 특히 개발기간 최소화 및 신뢰성과 신속한 통합시험수행을 위해 통합시험장비 개발이 필수적이다. 본 논문에서는 수리온(KUH) 임무탑재장비(MEP)의 각 장비별 특성을 분석 후 최적의 통합시험 수행을 위한 장비별 모델개발을 다루었다. 모델은 동작특성에 따라 동적(Dynamic), 행동(Behavior), 연동(ICD) 모델로 구분하였으며 장비의 고장탐구 및 미장착된 장비의 동작특성 모사가 모델링의 주목적이다. 모델은 소프트웨어 단위시험 및 체계 통합시험 두 단계로 나누어 객관적 신뢰성을 검증하였다. 수리온 MEP 통합시험장비(SIL)를 이용하여 개발된 모델을 통합시험에 적용한 결과 설계 목적에 부합됨을 확인하였다.

KASS (korea augmentation satellite system) 시스템 통합 및 검증(IVQ; integration, verification, qualification) 활동은 시스템 및 하위시스템 요구사항 검증 활동으로 IART(inspection, analysis, review of design, test) 기반으로 상세설계 (CDR; critical design review) 이후 하위시스템 공장수락시험 (FAT; factory acceptance test)부터 현장수락시험 (SAT; site acceptance test) 그리고 시스템 통합 검증 시험 (TRR; test readiness review) 까지 수행하였다. FAT 단계의 활동은 개발된 장비를 테스트 플랫폼에 설치하고 각 장비별 인터페이스 검증과 통합운영국(KCS; kass control station)과의 연동시험을 통해 성능을 검증하였다. SAT 단계의 활동은 FAT 단계에서 검증된 KRS (kass reference station), KPS (kass processing station), KUS (kass uplink station), KCS를 운영 현장에 설치하고 검증하는 단계이며 개발 일정 및 여건을 고려하여 3단계로 구분하여 수행하였다. TRR 단계의 활동은 항공위성1호기에서 방송되는 SBAS (satellite based augmentation system) 메시지를 이용하여 SAT을 통해 검증된 장비를 FAT 단계에 수행했던 시험 항목과 추가 시험 항목 검증을 통해 전체 시스템에 대한 성능 검증을 완료하였다.

The importance and cost of avionics system in the integration of an aircraft is continuously increasing. And we can expect enlarged software portion in the system integration for the more intelligent, reliable, and automated avionics system. Both military and commercial avionics community have moved toward commercial-off-the-shelf(COTS) equipment and open systems architecture not only to increase affordability but also to reduce acquisition cost, shorten development time and risk. The same concept is applied in developing avionics test system used for the avionics system integration test. In this paper, we present important topics in the development of avionics system including real-time operating system, interconnect data bus, software development methodology, software development process, and system integration test.

무인기 개발 시 항공전자시스템의 요구도 검증을 위해 통합시험능력을 제공하는 통합시험환경(SIL)을 개발하였다. 개발된 SIL은 유인항공기 SIL이 보유하고 있는 기능들을 기본적으로 제공하며, 각 구성품인 지상제어 모의, 비행체 모의, 비행환경 모의가 폐루프(Closed-Loop)로 연동되는 구조 하에서 시험 데이터의 가시화 및 시험자동화에 중점을 두고 설계되었다. 이로써 무인기의 복잡하고 수많은 요구도가 개발된 SIL을 통해 간편하고 정확하게 검증될 수 있었다. 개발된 SIL은 4단계의 검증과정을 통해 기능 및 성능의 정확성과 신뢰성이 검증되었으며, 무인기 지상체 및 비행체 통합을 위한 체계 SIL에서도 정상 동작함을 확인하였다.

This paper describes limitations and solutions of the existing processor-monitoring concept for a military supersonics aircraft Flight Control Computer (FLCC) equipped with modern architecture processor to perform the system integration test. Safecritical FLCC integration test, which requires automatic test for thousands of test cases and real-time input/output test condition generation, depends on the processor-monitoring device called Processor Interface (PI). The PI, which relies upon on the FLCC processor's external address and data-bus data, has some limitations due to multi-fetching capability of the modern sophisticated military processors, like C6000's VLIW (Very-Long Instruction Word) architecture and PowerPC's Superscalar architecture. Several techniques for limitations were developed and proper monitoring approach was presented for modem processor-adopted FLCC system integration test.
