Description
GME AIST120 AIS Transceiver Class B
The GME AIST120 is a Class B AIS transceiver acting as a vessel's electronic beacon, featuring a 50 channel internal GPS receiver, dual NMEA0183 and NMEA2000 interfaces, IPX7 construction, and IEC 61108-1 compliance.
Product Overview
GME's range of AIS transceivers, receivers, and splitters offers high performance and dependable reliability. The AIST120 can be considered a vessel's electronic beacon, providing boat owners with a vital navigation tool, particularly when operating at night or under poor visibility conditions.
Transmitted data includes vessel name, length, registration, speed over the ground (SOG), course over the ground (COG), as well as location coordinates automatically calculated and updated by the AIST120's integrated 50 channel GPS receiver. Through its ultra sensitive dual channel Rmax technology, the AIST120 receives and decodes transmitted AIS data from other vessels, AtoNs, and base stations within VHF range, which can be displayed on a compatible chart plotter, radar, or PC charting system.
Received AIS information positively identifies any commercial vessel within range, and also provides its radio call sign, heading, closest point of approach (CPA), and time to CPA. Using this information, leisure craft can make a VHF radio call to the vessel in question to verify its intended course and avoid collision. Through the application of TDMA technology, the AIST120 is compatible and inter-operable with both Class A and B AIS systems through the VHF radio data link. An internal GPS antenna makes for easy installation, with provision for an external GPS antenna input where required. The AIST120 has dual NMEA0183 and NMEA2000 interfaces for simple connection to stand-alone chart plotters or integration into more sophisticated onboard communication networks, and works in an autonomous, continuous mode regardless of whether operating in open seas, coastal, or inland areas.
Features & Benefits
50 Channel Internal GPS Receiver: The integrated 50 channel GPS receiver automatically calculates and updates the vessel's location coordinates for transmission.
Silent Transmit Mode Option: A silent transmit mode option is available where transmission isn't required or desired.
NMEA0183/2000 Compatible: Dual NMEA0183 and NMEA2000 interfaces simplify connection to stand-alone chart plotters or integration into more sophisticated onboard communication networks.
Class A and B Interoperability: TDMA technology makes the AIST120 compatible and inter-operable with both Class A and B AIS systems through the VHF radio data link.
External GPS Antenna Provision: While the internal GPS antenna makes for easy installation, provision for an external GPS antenna input is available for installations requiring it.
12-24V DC Input Voltage: Compatible with both 12V and 24V marine electrical systems.
IEC 61108-1 Compliant: Compliant with the IEC 61108-1 standard for shipborne GPS/GNSS receiver equipment.
IPX7 Construction: IPX7 rated construction provides protection against water immersion, suited to marine environments.
Low Power Consumption: Low power consumption helps minimise the load on the vessel's electrical system.
