Following ships via GMDSS

         Here's a short demonstration of how i can follow ships using their HF GMDSS signls. I initially use 3 programs (linked via com port) and in this case we are following the MOL KOMATI:

1) HDSDR to receive the signal via my Soft66LC4:

2) Patrick Lindeckers MultiPSK to decode the signal and send it to:

3) Mike Simpsons GMDSS Display program:

GMDSS showing vessels and details

           I would say that 99% of vessels out there do not send their position details due to many reasons, security being the main one. However, GMDSS Display has a function whereby pressing the ships code opens a Marine Traffic.com webpage showing not only the vessels details and pictures but also its current position and track:
