A RAW TCP/IP data stream connection can be set up for those (often older) GNSS Base Station devices which do not implement the NTRIP protocol. [The NTRIP protocol lives on top of the HTML protocol, which in turn uses TCP/IP to send packets of data, typically containing RTCM messages] Such […]
Using SNIP as a “bent pipe”
SNIP can be used in a “bent pipe” mode for any desired stream. In this mode, any data sent to it is available to be relayed to any client connection (as well as being logged). This mode of operation is commonly used where the Base Station data is not industry […]
How to Remove a Stream
Just right click on the stream, then select Disconnect or Remove. New users have asked how to remove a Base Station data stream. When an Evaluation copy of SNIP is registered as Lite, the number of allowed streams (slots) is reduced to three, often bringing this issue to the forefront. […]
Mixed data types with uBlox
Many people use RTKLIB and its STRSVR program to convert uBlox into RTCM 3.x message types before sending them to SNIP for distribution. This data can then be used by any devices that consumes RTCM 3.x data, although it contains only L1 observations. Others prefer to send the raw uBlox […]
Using STRSVR from RTKLIB with SNIP
This article discusses how to set up the RTKLIB tool STRSVR (aka stream server) to send data to a SNIP Caster node on the same, or on a different, machine. Many users of OEM boards across the cost spectrum use the STRSVR tool to convert (translate) from a GNSS vendor’s […]
The Preferences Dialog
This article describes how to set the controls found in the Preferences Dialog. This dialog is reached under the Edit menu by selecting the Preferences… item. The Preferences Dialog holds variety of settings that are used to control the basic behaviors of the Caster. Note: Not all features displayed are […]
When a Caster table entry is incomplete
There are several possible reasons a given Caster Table entry may appear to be empty or missing key data. This article covers the process of setting up Caster Table entries in greater detail. As a broad rule, you only need to provide these details for your serial port connections and […]
What is inside a uBlox6T evaluation model
This article first appeared in the forum topics of the original knowledge base support site. The uBlox 6T is a popular L1 only chip set used by many for short baseline RTK work. Prices for these devices range from just over ~125 US dollars to about ~350 in single quantities […]
A Typical One-Node SNIP Site
Often we get questions regarding using SNIP for “just one caster in my home-office-barn-garage” applications. And that is precisely why we created the free Lite model of SNIP to serve just that need. The Lite model provides a means to use your old PC *1 and whatever GNSS unit you […]
Alpha 0_8_8 Changes
What is new in the Alpha 0_8_8 release [May 16, 2016] SNIP underwent an extensive rework of the console logging functions in this release. More robust filtering abilities have been added to allow a finer control of what information is displayed. At the same time, an array of prior log […]
Stream Types.
Unlike most Casters, SNIP Supports four basic types of data streams: PUSH-In, PUSH-Out, RELAY, and UART. These are used to gather and send your different corrections streams to your clients. Two additional data stream types are also supported; a NEARest mountPt functionality and support for older RAW TIP/IP sockets are […]
Does SNIP support Bluetooth
Yes Any Bluetooth device which presents itself as a serial driver will work with SNIP. The connection between the device and the PC running SNIP is made like any other serial port. The serial port appears on the serial casters tab along with other devices. Setting up a new connection […]
Common Operating Tasks
Outline This article serves as a launching point to find the information on most common operational tasks in setting up your SNIP server. It links to other articles in the general knowledge base with further details. Setup Adding new data streams to SNIP: From another (remote) NTRIP Caster you have […]
Question: What is an NTRIP Client
An NTRIP Client is the software element used by the rover (the GNSS devices out in the field) used to connect to an NTRIP Caster such as SNIP to gain access to the data stream with the positional corrections it needs. There can be many hundreds of such clients connected […]
How do I setup SNIP with RTKLIB?
Basically just as you would any other NTRIP Caster. If terms like Caster, Client, and Server are still strange, read about them here. Most RTKLIB users employ the STRSVR tool to simply send data to the SNIP node using the “NTRIP Server Options” setting. The same basic dialog (shown at […]
