Auv Terrain Relative Navigation Using Coarse Maps

  title={Auv Terrain Relative Navigation Using Coarse Maps},
  author={Deborah K. Meduna and Stephen Rock and Robert S. McEwen},
Terrain Relative Navigation (TRN) provides an enabling technology for drift-free, low-cost navigation on many existing underwater vehicles. While highperformance TRN systems have been demonstrated using high-quality sensors and terrain maps, these systems can be very costly and the high-resolution bathymetry maps used are of limited availability. To extend the applicability of TRN, the authors previously addressed the performance trades in utilizing lower-cost, loweraccuracy sensor systems for… CONTINUE READING
