Remote Access Via Satellite

[Christos Papalas]

PLease advise if anyone has test or use remote access to Ship computer via A Sat com , i.e. Fleet 77/33 , Inm B?
If yes please advise results ( speed etc.)

What about 3G/GPRS access when in port ?? worldwide

Hi Christos,
You may visit us at stand-593 at Posidonia.
I think you can see exactly what you're asking for in real time...

Hi Christos,

Technically it is all possible, but consider whether it is cost efficient your you. I am working on a Requirements analysis for Broadband usage for Dutch shipping lines, please contact me in private if you would like to have more information or ask specific questions. I can be contacted on [e-mail].

Kind Regards,

Thank Ron ,

Your project about 'Broadband Usage' seems very interesting , and any information that can be provided I beleive it will interest our forum .

I will surely contact you in the near future.

Hi Christos,
I only tried with MPDS (Fleet77 by JRC) but of course not in MS Windows environment. As Ron said, it would be inefficient mainly due to high cost via MPDS or ISDN. I tried to access linux server onboard. At start installing VPN (openvpn) which although it worked in the begining, it was proved unstable. Next, I tried remote SSH with initiation from vessel ( using the -R parameter ) and this has been working flawlesly.
At any case consider the possibility to initiate a session from shore. In some cases as mine (JRC connected to ethernet port of BDE) is not possible to do it, so you need SW where the vessel can open a remote access session.

Thank you very interesting points !

I was trying to find a solution to a slightly different problem - a out-of-band remote management of the VSAT system onboard. This involves 3 or 4 serial devices of the VSAT system on board. I tried with serial servers, but F77 MPDS proved quite a challenge as regards to the more than 3 secs latency. Any one has good ideas?

[Ron Vollenga]

Dear Alan,

It is very difficult to overcome the latency issue. There should be some tools in the market which already respond, as if the other side is local installed on the vessel as well.

Another option might be installing a data compressor/repeater, although this will not take away the latency.


Kind regards,

Christos, Depending on where your vessel needs access, Hughes has integrated IP acceleration into its hardware to ensure efficient bandwidth usage for remote access, VoIP (like Skype), internet access, etc.. Satellite will always be slower than a land-line, but at least this product is tuned for maximum effectiveness. Its best used with a broadband VSAT service with fixed monthly rates - metered rates will not be effective. If you want more info, please do not hesitate to contact me [e-mail]

I onetime did it with vnc and some tweaks in the config worked out pretty good.

[Youri Hart]

to add 3g is a solution but it is also expensive roaming tariffs are high

[Christos Papalas]

3G was tested from our side with very good results .
Working in Chief Engineer PC unit from your home is really a challenge .
Of course roaming cost is one point and signal only in ports is the other point .
Nevertheless , is the only solution that you can have a good speed to perform REMOTELY various
on board tasks!

[Christos Papalas]

Furthermore and regarding roaming cost it may cost less if you restore a software operation remotely or provide guidance to the Crew comparing with visiting expenses !
