Recently I have been engaged in an assignment where I had to access MS Dynamics NAV through VSAT. Till date I have seen implementations with Dial-up connection,Broadband, or leased line but this was the first of its kind. To have some more knowledge about the vsat you can follow the following link

During the testing phase of this connectivity, I also tried to connect to the server directly with the client without using Citrix, the results were horrible. Please don't even try to perform the same for testing purpose also.
Secondly, We used citrix to connect to the NAV from the various remote locations. The Microsoft Dynamics NAV 4.0 SP3 was used with SQL Server 2005 to have the database server. Another server was configured which is used as the citrix server which is being acessed from the various remote ocations to login to MS Dynamics NAV. What I specifically want to discuss out here in this post is, the latency time taken to connect to the database compared to the other media such as dial-up, broad band etc with the VSAT.
Generally the connection is quite slow with 512kbps of line, opening up the login screen and entering into the database requires 10-15 secs of time, while navigation between the panes may differ from 5 to 7 secs. What I observed during this entire testing process is the posting of the various documents that are present in the NAV. The time taken to create the documents may differ from user to used based on the aquintence of the system, but the posting routines to my surprise takes the same time as you do the same in the client server architecture.
