DGNSS over the Internet - Client Instructions

EUREF-IP provides access to a number of DGNSS client programs. Note that Euref-ip-rtcm is the recommended Windows program for this project. Even if you need WinCE/PPC2002 software, you should run and explore that program first. It downloads a table of existing servers, decodes incoming RTCM corrections, and displays them in ASCII format.

You must connect the serial port of the client platform (your PC, Laptop, PDA) with the serial port of a DGNSS receiver when observing a position. It is recommended to select a high transmission rate for this link, such as 9600 bps, 19200 bps, or even 38.400 bps, if available, on both devices.

Firewalls often block communications through all but a few well-known ports. Because most of today’s servers provide their data through port 2101, you will probably need to connect your client through an Internet Service Provider instead of your company´s/agency´s (over-) protected LAN.

Euref-ip-rtcm shows the latency of incoming RTCM corrections. In order to get meaningful information, you need to synchronize your PC clock. Various programs exist for precise clock adjustments over the Internet. You can use NTPTime for Windows operating systems. Have a look on its documentation before installing.

Please note that by the end of 2002, new EUREF-IP dedicated free client software will need to be used to meet protocol definitions which are currently under development.
