RadarPlus SA161-UA – High Sensitivity Dual AIS Receiver for Avionics

Overview

The RadarPlus® SA161-UA is a globally-deployed, industry-proven AIS surveillance solution for integration at the circuit board level.

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.

RadarPlus SA161-UA – High Sensitivity Dual AIS Receiver for Avionics

The SA161-UA features low power consumption of less than 2 watts, and exclusive Shine Micro Enhanced Signal Processing (ESP) software. A GPS input provides slot numbering, VDL loading, and packet time of arrival information when using the ESP software. Future software upgrades are easily installed via the serial port.

The SA161-UA is designed for board-level integration with self-contained surveillance systems such as Unmanned Aerial Vehicles (UAVs), Unmanned Underwater Vehicles (UUVs), satellites, and more. Weighing just 2.50 oz. (70 g), the SA161-UA is ideal for land, sea, or airborne applications with limited payloads.

The ST162-T1 portable AIS Test Set is a recommended companion product to the SA161-UA, enabling operational optimization of AIS equipment and installations prior to deployment.
