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 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.

The effect of changing satellite geometry on the achievable accuracy of GPS relative positioning under the full GPS constellation has been researched. A mathematical model has been developed for the quantitative analysis of the accuracy of GPS relative positioning with respect to the changing satellite/station configuration, observation starting time and session length. A method based on modeling the relative dilution of precision (RDOP) has been developed for the optimum design of GPS relative positioning with carrier phase observable. The RDOP surface,...

청구항

[ We claim:] [1.] A method of determining the relative dilution of precision (RDOP) of a GPS measurement comprising:receiving signals from a plurality of GPS satellites at a first, fixed, known location;receiving the signals from the plurality of GPS satellites at a second, fixed locations;measuring the time of receipt of the signals;determining the RDOP of a measurement of the locations of the second locations with respect to the first location in accordance with the relative changes in satellite positions during the receipt of the signals.
