Approach

Hardware

  • Radios in SDR Lab
  • AIS → ASM → VDE
  • Starting with transmitter

Software

  • Open-source
  • GNU Radio Companion

○ Python/C++ blocks

AIS - Automatic Identification System

  • Ship ID, Position, Course, Speed
  • 9.6 kb Gaussian Minimum Shift Keying (GMSK)
  • High Data Link Layer
  • 2250 time slots established every 60 seconds
  • 20 Nautical Miles

ASM - Application Specific Message

  • Build off of AIS
  • Weather
  • Sea Level
  • Safety Concerns
  • IALA ASM

Constraints

  • Lack of Knowledge

○ We have limited knowledge on SDRs

  • Sponsor Location
  • Budget

○ SDRs are expensive!

  • Lack of VDE Info
  • Time
