Applications and Models
Search and Rescue, Ecosystem Management, Engineering, Marine Sciences, Coastal Navigation, Oill Spill Response – CODAR has a SeaSonde to meet your needs, whether they be long range, coastal or nearshore. The long-range model transmits the furthest offshore. The nearshore model provides the highest spatial resolution. All three models feature automated operation, remote control and data transfer via the Internet. A patented GPS synchronization technique allows a network of SeaSondes to operate at the same transmission frequency.

Long-range SeaSonde: Long-range CODAR SeaSondes operate within the 4-5 MHz frequency band and transmit 140 – 220 km offshore, depending upon local operating conditions. They provide synoptic surface current maps every hour or more and have an operator chosen spatial resolution of 6 - 12 km. Additional long-range SeaSonde technical specifications.

Coastal (Standard) SeaSonde: The standard SeaSonde operates within the 12-25 MHz band and transmits 20 – 80 km offshore. Typical spatial resolution is 1 to 2 km. Additional Standard SeaSonde technical specifications.

Nearshore (highest resolution) SeaSonde: Nearshore SeaSondes are designed for smaller areas requiring high spatial resolution, such as bays, ports and harbours. They operate at 40-50 MHz, which is within the VHF band, typically have spatial resolutions of 75 – 500 metres and operate up to 10 km from shore. Additional nearshore SeaSonde technical specifications.
