Teledesign Delivers Radio Modems to Seattle District

Teledesign Systems Inc. has delivered 20 of their new model TS4000 radio modems to the Seattle District Corps of Engineers for use in dredge positioning and navigation. The transmitter/receiver units will be installed along with GPS receivers at known points along navigation channels in the district and will transmit position corrections to receivers on dredges and survey boats for centimeter accuracy.

The company’s AirNet packet protocol allows one unit to transmit to receivers on a number of dredges and survey boats.
