Introduction
The document introduces the SI-30A Universal Automatic Identification System (UAIS), highlighting its unique features such as built-in worldwide port maps and AIS data interfacing with various GPS plotters. It is the first of its kind to integrate these functionalities.

General Specifications
The SI-30A operates with a power consumption of 50W peak and 10W average, powered by a 12V DC supply. It supports default frequencies for AIS and DSC channels and has a frequency range of 156.025 to 162.025 MHz. The transponder and MKD display have specific dimensions and weights, with the MKD featuring a 5.6” color TFT LCD.

AIS Transmitter and Receiver
The AIS transmitter outputs power at 12.5W or 1.0W with an antenna impedance of 50 ohms. The receiver has a sensitivity of less than 20% PER at -107 dBm and supports GMSK modulation with a data rate of 9600 bits/s.

DSC Receiver
The DSC receiver features a sensitivity of BER <10-4 at 107 dBm and uses FSK modulation.

Serial Inputs/Outputs
The system includes multiple serial inputs and outputs compliant with IEC61162-1/2 standards, supporting both input and output functionalities.

GPS Antenna & Receiver
The GPS system includes a patch antenna and a 16-channel receiver with high acquisition and tracking accuracy.

Environmental Conditions
The device operates within a temperature range of -15°C to +55°C and can be stored between -25°C and +75°C. It complies with IEC 60945 vibration standards.

Standards and Compliance
The SI-30A complies with various international standards, including IMO MSC. 74(69), IEC 61993-2, and ITU-R specifications. It is ISO 9001:2000 certified.

Features
The system supports dynamic and static navigational data display, is compatible with NMEA standards, and allows user message editing. It interfaces with RADAR, ECDIS, and other navigation systems, enhancing ship status identification through electronic chart data.

Components and Options
The system includes a transponder unit, MKD unit, GPS & VHF antennas, and optional components like a DGPS receiver and GLONASS module.
