연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A sensor system for monitoring for the presence of contamination with one or more contaminating biological, chemical and/or radioactive agents on a terrain surface, and creating a contamination map thereof. The sensor system includes a plurality of sensor pods, a ground station, an airborne dispensing portion, and an airborne monitoring portion. The sensor pods include a pod housing, a descent slowing airfoil, a detector unit for detection of the contaminating agent and outputting contaminating agent data, a processor for processing the contaminating agent data, a GPS unit for determining the position of the sensor, and a transmitter for transmitting contamination agent data and position data to the airborne monitoring portion. The airborne monitoring portion receives the transmitted data from the sensor pods, and relays the data to the ground station, where the contamination map is made available.
