Abstract
Accurate underwater positioning remains an important challenge to AUV researchers. Recent development of Differential Global Positioning System (DGPS) embedded in an AUV proved the capability of DGPS fixes to reduce the position error. By surfacing regularly, the AUV takes DGPS fixes and integrates them for position estimation. The purpose of this study is to develop a low-cost DGPS for the NPS AUV. To match mission requirements, the system is designed such that the differential receiver and the GPS receiver are two independent stations using radio modems to communicate. Local experimental testing showed that this system can yield positions within one to five meters accuracy.
