RBS-1 and RBS-2 Baseline Stations

Baseline Stations serve as the reference points for positioning in long baseline systems.  They are used in diver survey, ROV survey, and AUV navigation applications.  At the beginning of a job, these stations are deployed near the corners of an underwater work site.  Positions are measured with sub meter accuracy by interrogating the baseline stations and measuring the signal run time.  Normally, a set of three stations is used to obtain high quality, unambiguous position fixes.  However, you can use either two or four stations in some cases.  The stations are usually mounted several meters off the sea floor, anchored by a line, and buoyed by their flotation collar.  Rigid mounting on a pole is preferred in high surge applications and when centimeter accuracy is required.  All baseline stations support an automatic baseline survey (also known as sonar sing around).  This eliminates the need to place stations precisely. Select our RBS-0, RBS-1 or RBS-2 depending on your range, depth, battery life, and system configuration requirements.   Baseline Station Specifications
