The Ocean Signal ATB1 is a powerful Class B AIS Transponder incorporating the superior SOTDMA technology and 5W output power to ensure increased visibility and navigational safety for leisure boat owners and captains. The new fully-compliant Ocean Signal AIS unit uses the SOTDMA (Self Organised Time Division Multiple Access) scheme to provide enhanced navigational safety and added assurance that the vessel will be seen day or night.  The Ocean Signal ATB1 has a faster reporting rate and higher output power than standard CSTDMA (Carrier Sense TDMA) Class B units, sending AIS transmissions every five seconds instead of the CSTDMA two transmissions per minute. The unit’s 5W output power, compared to the standard 2W, allows the transmissions to reach further.

The ATB1 Class B AIS Transponder is priced at £590 excluding VAT.
