Beta 0_9_2 Changes
What is new in the Beta 0_9_2 release [July 1st, 2016] This is the third public Beta release, (prior SNIP releases were Alphas with a limited release distribution). A problem with the way caster strings from PUSH sources were processed, first found in release 0.9.0, has resulted in reworking the table […]
NMEA GGA Strings in NTRIP Clients
What are NMEA-183 GGA sentences? NMEA-183 GGA sentences are used by NTRIP Clients to inform the NTRIP Caster where they are (and hence the location they require corrections for). The use of the GGA sentence is found most often on virtual reference station (VRS) networks and on networks using NEAR […]
Caster String Settings in RTKLIB
One of the more complicated details when using the RTKLIB tools to push data to SNIP is how to set up the Caster table “string” entry in the dialog box shown below. This article deals with how to correctly enter this data. Aside: RTKLIB provides an NTRIP Server function only; […]
Basic Navigation Chart Types
SNIP supports two basic navigation filters along with various charts which can be used to display the resulting solutions. The displayed charts are responsive to mouse-over tracking, providing additional data details as the mouse hovers over each data point. A simple least squares type filter, and a basic PPP style […]
Debugging User Connections with a closed caster
This article covers the various errors and reporting messages that can occur when SNIP is operating in a closed mode such that every new user (every NTRIP Client) must present a valid account and a password in order to log in. If SNIP is operating in an open mode, the […]
User Connections, general debugging
This article covers the various errors and reporting message that can occur when SNIP is operating in a closed mode such that every new user (every NTRIP Client) must present a valid account and a password in order to log in. If SNIP is operating in a open mode, the […]
Beta 0_9_1 Changes
What is new in the Beta 0_9_1 release [June 16, 2016] This is the second public Beta; prior SNIP releases were Alphas with a limited release distribution.

Beta 0_9_0 Changes
What is new in the Beta 0_9_0 release [June 03, 2016] This is the first public Beta, prior SNIP releases were Alphas with a limited release distribution. The basic visualization and navigation solution charting abilities in SNIP were expanded and some additional user control elements were added. The new visual elements […]
Using the Serial UART Connection Wizard
The serial stream configuration wizard provides a simple step-by-step method to add a new serial data stream to your SNIP Caster. This guide will give an overview of each step in the stream configuration in the wizard. Getting started: The serial stream configuration wizard can be located under the menu item “Control->Add Serial […]
Determining whether a stream contains orbital ephemeris data
This article demonstrates detailed debugging using SNIP’s RTCM3 Decoder dialog to determine what messages are present in a given connection stream. Background One of the common issues when a client claims things are suddenly not working is that they no longer have access to a suitable set of ephemeris messages […]
Observing SNR and the cycle slip counts
This article demonstrates detailed debugging using SNIP’s RTCM3 Decoder dialog to determine the general quality of the observation messages present in a given connection stream. Background A common issue when a given correction stream and a target rover which then fails to achieve rapid ambiguity resolution (AR) into a fixed […]
Determining Message Repetition Rates
This article demonstrates detailed message analysis using SNIP’s RTCM3 Decoder dialog to determine what messages are present in a given connection stream. Background The primary reasons to select one stream over another are typically that it has the message content you seek and that it is suitably close to where […]
Debugging Client Connections
This article demonstrates detailed debugging of an NTRIP Client Connections using SNIP’s filter controls to reduced the console log to meaningful content. Background One of the most common issues for a Caster operator is assisting your user community to get connected. Users have many issues, but here we will consider […]
Using the Relay Wizard to Set Up A New Relayed Caster Stream
The Relayed stream configuration wizard provides a simple step-by-step method to add a new relay data stream to your SNIP Caster. This guide will gives an overview on each step of the stream configuration process in the wizard. Getting started: The relayed stream configuration wizard can be located under the menu item “Control->Add […]
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 […]
Filtering by Stream Types
The console also supports filtering the type of entries by basic Stream Types. This allows you to display or hide major portions of the console content. You can enable or disable filters for: Client Details Events when your NTRIP Clients attempt to connect and disconnect Relayed Caster Details Events when […]
Filtering by Stream Name (by mount point)
The SNIP console supports filtering displayed entries by their Stream Name (by their published mount points). The list of mountPt entries changes dynamically as streams are added and removed in the Caster. The image below shows the drop-down menu with a set of mountPt (from various US States, AL, CA,and […]
How to use Filter Controls, the details
SNIP has a powerful console filtering mechanism built into the tool. These controls allow the log to be re-displayed with filtering of its content. This allows displaying in the log ONLY what you the administrator need to see,rather than trying to read over the log when potentially many thousands of […]
