Let's suppose I have a Trimble 4800 base station connected to my PC via serial port, with an antenna cable running up to the roof. On my PC, which is connected to the internet and has a static IP address, I have installed GNSS Surfer and would like to be able to broadcast corrections and retrieve them through a direct connection to my server IP on my data collector through my cell phone.
Does anyone have experience doing something similar and, if so, would you mind sharing your knowledge on how to go about this? GNSS Surfer has a lot of options and I haven't clicked the right combination of buttons yet it seems.
I have the 4800 outputting corrections to a custom radio on port 3 and I can see the information in hyperterminal.. it is flowing through the port, but I don't seem to get anything in GNSS Surfer except for an error:
too few Byte per TimeUnit: 0_is_too_few_Byte
failure_start 12.08.2013
23:39:20CharWatch: TcpOutServer-Warning !
Any help or input would be greatly appreciated.
If you're asking why I'm doing this, the answer is that it's the first step in build my cellular RTK setup on the cheap.
Edit: For clarification, I believe I understand how to configure the base and rover.. it's the GNSS Surfer software in the middle I'm having so much trouble with. It seems clear, but the software doesn't seem to see the data coming in.
Do you have wi-fi turned on?
I thought you meant this!
That's the first thing that came to my mind when I read the subject line of the post. Especially after spending last week down at Long Beach Island watching my son surf. 😛

I hope he has the difference between the end of the rod and the board accounted for or his elevations will be off. Let alone the difference between the board and the water. I'd had a hard time accepting his results due to those anomalies. 😀
Well, after a fair amount of fighting GNSS Surfer I gave up and decided to look for another port forwarding software and found TCP-COM:
It's very simple interface allows me to select the com port, then set the outgoing IP and port. I configured it and then set up my rover as a RTK using Internet connection, Bam, was fixed in about 30 seconds.
I currently am sitting here stunned that it was this easy... GNSS Surfer sure made it seem more difficult.
I thot he meant "Do you have Wifey turned on"?
Shows what I know.

After reading the post and thinking about it. What are the pros and cons for doing this? I'm starting to think this might be a good thing.
I ended up getting it to work and used it all last weekend. Fantastic.
My base outputs corrections to my raven modem that sends them to my server, my server redirects them out to my static IP, where my rover looks to get them.
Many benefits:
- Virtually unlimited RTK range using a custom base.
- Fast initializations, data transfer is very fast.
- Reliable as your cell phone connection.. no radio weak spots.
- Multiple crews running off same base.
- No stupid radio/narrow-branding issues.. all done via internet.
- You get actual vector lines in your data, not just points from VRS.
- No annual VRS fees.
