RadarPlus® SA161-MH – High Sensitivity Dual AIS Receiver for Aircraft

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


The RadarPlus® SA161-MH is a globally-deployed, industry-proven AIS receiver for aircraft.

Over 250,000 ships worldwide transmit position and identity information via the Automatic Identification System (AIS). Increased AIS tracking range and concentration is achieved by Shine Micro AIS receivers for aircraft. Industry-leading sensitivity is attained through Shine Micro exclusive I/Q Synchronous demodulator technology, facilitating superior reception of noisy, weak signals.

Enclosed in a fully-shielded and NVIS-compatible aluminum case, the SA161-MH is rugged, light weight, corrosion resistant, and capable of high altitude operation over a wide temperature range. Mounting options include a Type 1 Aircraft Dzus Rail or a bottom flange mount.

The SA161-MH features dual outputs via Ethernet and RS-232. Both 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.


• High Sensitivity
• MIL-Spec Construction
• Low Power Consumption
• Integrated 12-Channel GPS
• Superior RF Input Protection
• High Altitude Operation
• Wide Operating Temperature Range
• Exclusive Shine Micro Enhanced Signal Processing Software (ESP)

The Shine Micro companion product ST162-T1 AIS Test Set is recommended for optimization
of AIS equipment and installations prior to deployment.

The SA161-MH and ST162-T1 are COTS equipment and standard options on Lockheed Martin/Sikorsky MH-60 Helicopters, Lockheed Martin P3 and Boeing P8 aircraft, Insitu
Integrator™ UAS, and many others.
