NTRIP Server Configuration
Starting from version 1.9.0, ELT_RTKBase includes five NTRIP servers. Each NTRIP server can operate in five different modes.
The most universal mode is NTRIP v1. In this mode, you can filter RTCM3 messages using the “Rtcm messages” field. This mode allows you to connect to any NTRIP caster.
The NTRIP v2 HTTP mode is considered a more modern option. In this mode, not only the password and mount point are specified, but also the login. If the NTRIP caster does not support this mode (or if the login field is empty), the system automatically falls back to NTRIP v1.
The NTRIP v2 RSTP mode is the highest-quality mode with minimal overhead. It handles short-term connection interruptions better than other modes. The main drawback is that this mode is not implemented in most NTRIP casters.
The NTRIP v2 UDP mode is an experimental mode. At present, it is practically not implemented anywhere.
The TCP client mode is the simplest mode. It is intended for communication with a TCP server.
Thus, our equipment can operate both as a TCP server (a description is provided in the “” section) and as a TCP client.
The Onocoy NTRIP caster (servers.onocoy.com) is somewhat special. On Onocoy, the mount point name changes depending on the coordinates of the base station. For this reason, we implemented dedicated handling for this NTRIP caster. For example, the login field is used for identification even in NTRIP v1 mode.
RTCM3 Proposals
In the settings of all services, except for Main and File, there is a list of transmitted RTCM3 proposals. After the proposal number, you can specify the period (time in seconds between proposal transmissions). This is especially relevant for the caster.
