WHAT IS MANTA? MANTA is a multi-mode data telemetry and data logging system designed for real-time tracking and monitoring of large marine vertebrates.
l Real-time 3-D underwater acoustic tracking l Real-time VHF tracking l Data-logger capable depthdepth tilt/roll sensortilt/roll sensor acoustic and other sensorsacoustic and other sensors l Data telemetry via an acoustic modem (limited transmit rates < 150 bps) MANTA Capabilities
How are underwater locations determined? l Slant range estimated from signal return time l Horizontal bearing estimated from time delay at receiving array (surface station) l Depth is measured at tag and acoustically transmitted to surface station Three quantities needed: 1) Range 2) Bearing 3) Depth
