DGPS over NTRIP GPS settings

A) Set up GPRS connection
Start - Settings - System tab, click"gprsset" icon...
Image


On this new window click the "Set a new connection command:"
- Your mobile provider give you the APN name, frequently it is INTERNET, but somtimes it can be another word - Change the proper word in the next string:
Code: Select all
AT+CGDCONT=1,"IP","INTERNET"<cr>


Image

B) Initialize the internet connection
Start - Settings - Connections tab, "Connections" icon,
On the new window - in Settings: under MyISP click the row:
"Manage existing connections"
Image
- Select the line "GPRS Connection" and "*99***1#" in Number, tap and hold and select "Connect".
Image

C) Set up the NTRIP in DigiTerra Explorer 7
Settings -> DGPS tab, Correction: NTRIP,
IP/port/user/password: provided by the NTRIP provider.
Mount point:
- I suggest to you using "position-based" correction (- type: SGO)
And finally, set up the Port: COM4 19200
