Mounting Options for SA161-MH MIL-Spec dual AIS receiver for avionics
Mounting Options for SA161-MH MIL-Spec dual AIS receiver for avionics


The RadarPlus® SA161-MH applications include vessel tracking and maritime surveillance. The unit is designed for normal operation over a wide temperature range of -40° C to +70° C and at altitudes up to 70,000 ft.

Industry-leading sensitivity and tracking range are achieved through I/Q Synchronous demodulator technology, which demodulates AIS packets for superior reception of noisy, weak signals. The SA161-MH provides the most sensitive AIS reception in the harshest of environments.

Enclosed in a fully shielded aluminum case with NVIS-compatible surfaces, the SA161-MH is corrosion resistant, light weight, and rugged. Mounting options include either a Type 1 Aircraft Dzus Rail or an oversized bottom flange mount.

The SA161-MH features dual outputs via Ethernet and RS-232. Both protocols may be utilized to receive data from the device simultaneously. The Ethernet module is configurable as TCP server, TCP client, UDP point to point, or UDP broadcast.

Serial Interface Details

The serial interface of the SA161-MH conforms to ITU-R M. 1371- 4 and NMEA 0183 data protocol with additional proprietary sentences. Received AIS messages are reported using the NMEA 0183 VDM sentence. GPS position data is reported using the GGA, ZDA and VTG NMEA 0183 sentences. Data is simultaneously output via RS232 and Ethernet. The Ethernet module is configurable as TCP server, TCP client, UDP point to point, or UDP Broadcast at 10/100 Mbps.
