Step #2 Base Station Setup:

SNIP has several methods to connect to GNSS Base Stations

Select which one of the four use cases below best describes your situation:

Serial Port Serial Base Station Setup

The Base Station is connected to the PC running SNIP with a serial port or a USB serial port adapter. Use this method when the GNSS Base Station does not have either a built-in NTRIP Caster/Server or the ability to send data over the internet.

In SNIP the Serial Streams tab is used to control all the serial connections.

In order to exchange messages, you will need to ensure that the serial port settings (baud rate, parity, etc.) on both the GNSS device and SNIP use the same settings. Ensure the GNSS device will send the correct messages as well, typically RTCM revision 3, but other messages can be used. Consult the documentation provided by the device vendor in order to correctly set that side.



Push-In PUSH-In Connections

The Base Station is remote from the PC running SNIP with internet access.

The Base Station uses its own NTRIP software to send data (acting as an NTRIP Server) to SNIP. [Some deployments elect to use a 2nd copy of SNIP to PUSH-Out data]

The remote Base Station initiates the connection, which may have a prior 'reservation' created for its use.

In SNIP the PUSH-In Streams tab is used to control all the connections of this type.




Remote-Relay Relay Connections

The Base Station is remote from the PC running SNIP with internet access.

The Base Station has its own NTRIP Caster (built-in, or SNIP, or any other Stds conformance Caster).

In this configuration SNIP connects to the remote NTRIP Caster (as an NTRIP Client) and then relays data from the remote connection back for use.

Here SNIP initiates the connection. [Many GNSS Base Stations have a simple Caster that can send its single data stream to users.]

In SNIP the Relay Streams tab is used to control all the connections of this type.




Raw Raw TCP/IP Connections

The Base Station is remote from the PC running SNIP with internet access but does not have a NTRIP Caster of its own.
Nor is a copy of SNIP available for use. These are typically older GNSS Base Stations.

In this configuration the remote Base Station connects to SNIP but is unable to follow the NTRIP protocol.
SNIP accepts the data on a dedicated port for each remote device and uses its ability to auto-parse the data to create a correct Caster Table entry.

Here SNIP creates an active server socket at the defined port, then waits for the remote GNSS device to initiate the connection.

In SNIP the Raw TCP/IP tab is used to control all the connections of this type.

Note: The Raw TCP/IP feature is not available in the Lite model of SNIP.
