Maritime AIS Class B Transponder Radio for pleasure craft, smaller fishing vessels, and yachts

DESCRIPTION: Having already developed an Automatic Identification System airborne receiver, we set out to design a compact AIS Class B Transponder for international maritime operation. Our AIS B solution utilized a Xilinx® Spartan-6® based software defined radio resulting in extremely clean transmit bursts, and an extremely sensitive AIS receiver. We wrote the AIS protocol stack to run on the onboard ARM processor. A vast number of different I/O options were supported. This system is a great example of Fidus delivering complex hardware, RF, FPGA, embedded software, and mechanical design- a real turnkey project.

This product was independently tested and complied with the international AIS protocol and RF performance requirements.

TECHNOLOGIES: Xilinx® Spartan-6® FPGA, uBlox® GPS, I2C, SPI, JTAG, software defined radio (SDR), RF, 1 to 12.5W transmit power, VHF, SMB, 10/100Base-T Ethernet, USB 2.0, UART, RS232, ADC, DAC, ARM processor, high power buck-boost converter, automatic gain control, automatic attenuation control
