The Filter Log Threshold Control is the primary means by which you can control the level of reporting details shown in the console. Whenever you change this setting, the log is redrawn using the new setting. This allows reviewing both past and present log events with more or less detail. […]
Changing your IP address
The normal mode for the SNIP Caster is to reuse the last IP address and port number which you selected every time it runs. This address is then known by your NTRIP Clients, because you used a static IP or because you used a dynamic DNS with port forwarding. [During […]
Message Monitoring
Message Monitoring When the detailed content of one or more specific messages needs to be examined, SNIP provides a basic RTCM3 message decoder in a dialog for viewing the message details from multiple streams at once. The menu item is called “Show in RTCM Viewer.” This detailed decoding requires that […]
Current Connections Report
Current Connections Report Each of the data stream tabs also provides a “List MountPts” button on the lower right hand side which can be used to display a terse summary of all active mountPt, highlighting any with issues in red and indicating for how long the condition has persisted. A […]
Graphical Monitoring
Graphical Monitoring There is often a common need to use the data streams to perform a basic navigation filter in order to provide visual feedback regarding the stream data. Often advanced users will use 3rd party tools to monitor specific details of the data signals, simply connecting to their own […]
Monitoring a stream, text and graphical tools
The need to monitor the data quality in one or more of your Caster streams is a common one. The information presented on the tabs provides an easy color coded way to quickly view the stream’s status. Color is used to draw the operator’s attention to streams that are not […]
Alpha 0_8_6 Changes
What is new in the Alpha 0_8_6 release [April 13, 2016] SNIP underwent a general rework of the loading logic in the Relay Streams Tab to make editing and adding streams easier. Now, rather than selecting an existing file with the list of casters to be loaded and run, the […]
Using the RTCM3 Decoder Dialog
The RTCM3 Decoder Dialog provides a real time summary of decoded RTCM3 message type contents from one or more streams at once. You can use the RTCM3 Decoder to confirm the presence or the absence of specific message types in the stream, and to examine the detailed data being sent. […]
Using the Universal Decoder
The Universal Decoder provides a textual summary to the console of the message contents seen in a selected stream. It can be used to detect and decode various message protocols and types mixed together in a single data stream including types such as RTCM3, RTCM2, NMEA-183, uBlox Raw, Hemisphere raw, […]
Sending Serial Commands Dialog
Remains to be published. Will be a walk through a more complex serial command sequence with the universal message decoder enabled to see the traffic.
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 […]
Connecting Serial Ports and USB to your PC
To connect a serial stream in SNIP see the article: Adding Serial UART Data Streams To understand issues with drivers, see the article: Problems with USB / Serial Drivers To understand and connect all the physical cables needed, read on… This article covers a few products and best practices on […]
Antenna Supporting Hardware
In the image below is our recommended L1/L2 GPS/GLONASS antenna for general purpose RTK work as well as some useful items to mount it. Click on it twice if you want an extreme high res image. The device shown here is an Antcom 53GO1216A4-XS-1 antenna. You can read more about […]
GNSS & GPS Overviews and Links
New to GPS ? (the preferred term these days is “GNSS” include all the different satellite systems). There are any number of web-based educational resources which can teach you about how it all works. The presentation depth ranges from very solid descriptions using almost no math, to those with more […]
How to read a MountPt string
A MountPt (or a “mount point” when the term is fully spelled out) is the specification by which an NTRIP client connects to a data stream on an NTRIP Caster. Often the term refers to just the unique string name, and most NTRIP clients think in terms of that string. […]
How to locate your own reference ant.
This is fast and dirty set of process steps to determine where a stationary reference station antenna (or any GNSS antenna for that matter) is placed. It requires several hours of raw observational data to be collected, and then sending your data set to 3rd parties to determine the position. […]
Alpha 0_8_3 Changes
What is new in the Alpha 0_8_3 release [March 17, 2016] SNIP underwent a general rework of the Serial Streams Tab to make it more like the other tabs. The same “spread sheet” view used in the other tabs is now used to cleanly show the status of each stream […]
Question: What Antenna should I use?
Probably not the one you have now if you are asking this question. We presume in this FAQ that you have obtained a low cost L1 device, and that you wish to do RTK navigation to obtain ~2cm accuracy over moderate to short baselines. If you received a small magnetic […]
An RTCM 3 message cheat sheet
We are often asked for a list of what the most common RTCM version 3 messages are. Here is a handy cheat sheet to answer this. The first section lists the messages which you are most likely to be concerned about. But if you are developing PPP filters or state […]
