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.

A method for configuring a local positioning system comprises orienting a survey antenna coextensively with a primary beacon associated with a work area. A transmitter or transceiver transmits a first transmission signal from the survey antenna. A receiver or transceiver receives the first transmission at one or more secondary beacons associated with the work area. A data processor determines first elapsed times from the transmission time of the first transmission signal to at least the arrival time at respective corresponding secondary beacons. Each of the first elapsed times falls within a filtering time window, or satisfies an edge timing criteria of the coded signal, or both to reduce multi-path error. The first elapsed times are converted into a first position in at least two spatial dimensions for the primary beacon.

What is claimed is: 1. A method for configuring a local positioning system, the method comprising: orienting a survey antenna coextensively with a primary beacon associated with a work area; transmitting a first transmission signal from the survey antenna; receiving the first transmission at one or more secondary beacons associated with the work area; determining first elapsed times from the transmission of the first transmission signal to at least the arrival at respective corresponding secondary beacons, each of the first elapsed times falling within a filtering time window to reduce multi-path error; and converting the first elapsed times into a first position in at least two spatial dimensions for the primary beacon. 2. The method according to claim 1 further comprising: inputting a maximum dimensions of the work area; determining a maximum propagation time associated with the filtering time window based on at least one of the maximum dimensions and geometry of the work area. 3. The method according to claim 1 further comprising: determining a minimum propagation time associated with the filtering time window based on a reception of the first transmission exceeding a threshold signal-to-noise ratio, a threshold signal strength level or a threshold signal quality level at one or more of the secondary beacons. 4. The method according to claim 1 wherein the determining of the first elapsed times comprises outgoing propagation times from the first transmission to the respective secondary beacons plus incoming propagation times from second transmissions of derivative signals, based on the first transmission, to the survey antenna. 5. The method according to claim 1 further comprising: orienting the survey antenna coextensively with a particular one of the secondary beacons; transmitting a second transmission signal from the survey antenna; determining second elapsed times from the transmission of the second transmission signal to at least the arrival at corresponding secondary beacons and the primary beacon; and converting the second elapsed times into a second position in at least two spatial dimensions for the particular secondary beacon; and establishing a reference coordinate system based on the first position and the second position. 6. The method according to claim 5 further comprising: establishing at least one of a path plan and a mission plan based on the guidance of the vehicle with respect to the reference coordinate system. 7. The method according to claim 5 further comprising: presenting the first and second positions on a display to a user; allowing the user to enter input data to facilitate revision of at least one of the first position and the second position. 8. The method according to claim 1 wherein the survey antenna comprises a beacon antenna of the beacon. 9. The method according to claim 1 further comprising disabling the transmitter or receiver associated with the beacon with which the survey antenna is co-located. 10. The method according to claim 1 further comprising: mounting the survey antenna to a vehicle; and driving the vehicle around a perimeter of a work area to define the perimeter. 11. The method according to claim 1 further comprising: mounting the survey antenna to a vehicle; and driving the vehicle around interior perimeters of at least one of a keep-out area and a no-entry zone within an interior of the work area. 12. The method according to claim 1 wherein the receiving further comprises: determining whether the edge or transition of a coded signal associated with the received first transmisstion is consistent with a timing of previous pulse edges of the received first tranmission; and applying at least one of selective delay and amplitude modification or both to the coded signal to temporally align a code phase of the coded signal to a desired code phase. 13. The method according to claim 12 wherein the receiving further comprises: rejecting estimated propagation delays or estimated locations outside of the filtering time window for the beacons that are inconsistent with the spatial dimensions, layout, and geometry of the work area. 14. The method according to claim 12 wherein the receiving further comprises: rejecting estimated propagation delays or estimated locations outside of the filtering time window for the vehicle that are inconsistent with the spatial dimensions, layout, and geometry of the work area. 15. A method for configuring a local positioning system, the method comprising: transmitting a first transmission signal from a primary beacon; receiving the first transmission at one or more secondary beacons associated with the work area; determining first elapsed times from the transmission of the first transmission signal to at least the arrival at one of the respective corresponding secondary beacons, each of the first elapsed times falling within a filtering time window; and converting the first elapsed times at the primary beacon into a first position in at least two spatial dimensions for the primary beacon. 16. The method according to claim 15 further comprising: inputting a maximum dimensions of the work area; determining a maximum propagation time associated with the filtering time window based on at least one of the maximum dimensions and geometry of the work area. 17. The method according to claim 15 further comprising: determining a minimum propagation time of the filtering time window based on a reception of the first transmission exceeding a threshold signal-to-noise ratio, a threshold signal strength level, or a threshold signal quality level at one or more of the secondary beacons. 18. The method according to claim 15 wherein the determining of the first elapsed times comprises outgoing propagation times from the first transmission to the respective secondary beacons plus incoming propagation times from second transmissions of derivative signals, based on the first transmission, to the survey antenna. 19. The method according to claim 15 wherein the receiving further comprises: determining whether the edge or transition of a coded signal associated with the received first transmission is consistent with a timing of previous pulse edges; and applying at least one of selective delay and amplitude modification or both to the coded signal to temporally align a code phase of the coded signal to a desired code phase. 20. The method according to claim 19 wherein the receiving further comprises: rejecting estimated propagation delays or estimated locations outside of the filtering time window for the beacons that are inconsistent with the spatial dimensions, layout, and geometry of the work area. 21. The method according to claim 19 wherein the receiving further comprises: rejecting estimated propagation delays or estimated locations outside of the filtering time window for the vehicle that are inconsistent with the spatial dimensions, layout, and geometry of the work area.
