VPS fish tracking system is a low cost, acoustics principle of non fish positioning system, based on real-time firstly,several VR2W receiver cloth on the studied area,composed of monitoring network, and then the fish acousticmarkers in fish. The VR2W receiver monitoring network can be continuous tracking and locating marked the acoustic signature of fish with high precision, Canada VEMCOcompany provides data processing business, the final results by VEMCO company in Canada to end users. The VPS system is very suitable for fish behavior at small scalestudies.

Technical specifications

Real time positioning, non  - positioning accuracy: 1m to15m

Tracking the long-term trajectory  - small scale

VR2W array under water network, usually triangular or rectangular array.

His request is each acoustic markers to ensure that at least 3 receiver can receive the same signal, the more the better.

In order to realize the monitor range overlap between the receiver 100%. In order to realize the monitor rangeoverlap between the receiver 100%. At the same time, each receiver configuration of a Synctag, namely timesynchronization, synchronization receiver for all time. The receiver is a built-in real-time clock, but each receiver clockdue to the drift and are not synchronized, so it will affect the accuracy in the calculation of position, so every VR2W to configure a Synctag. The receiver is a built-in real-time clock, but each receiver clock due to the drift and are notsynchronized, so it will affect the accuracy in the calculation of position, so every VR2W to configure a Synctag. In order to assess the accuracy of the system, achieve the purpose of quality control system, but also equipped with reference markers (reference tags), usually 6 VR2W configuration 1 reference marks, reference marks the location is known, isused for monitoring system in measuring the state of good.
