Abstract : This document describes a remotely trackable drifter system which has been developed which will enable up to ten drifter units to be monitored from a vessel or a shore station. The design, configuration and testing of the system is described in detail. The base station continuously receives data from the drifter units. Individual drifters are equipped with Global Positioning System sensors, radio modems and radios and transmit their position to the monitoring station. The monitoring station consists of a receiving radio, radio modem, personal computer and software. Each component of the entire system has been tested and proved under field conditions. If differential correction is not undertaken, positional accuracy of about loOm can be expected. If differential correction of the data is completed, positional accuracy of better than 10 m can be expected. The design has been proved at the prototype stage, expanded, composite systems consisting of larger numbers of drifter units (up to 10) can now be constructed and put into use in a range of estuarine and coastal applications.
