An NTRIP Caster<\/strong> is the real server element in the overall NTRIP system<\/a>. \u00a0\u00a0
\nSNIP <\/span>is an NTRIP Caster.\u00a0\u00a0<\/strong>\u00a0\u00a0 Go to SNIP download page<\/a>
\n<\/strong><\/p>\n

An NTRIP Caster takes data from one or more data stream sources (Base Stations referred to as NTRIP Servers<\/a>) and provides this data to one or more end users (often called rovers), the NTRIP Clients<\/a>.\u00a0 If you need to send data to more than one client at a time, or have more than one data stream, you will need a Caster.<\/strong><\/p>\n

\"NTRIP_Caster\"<\/a><\/p>\n

NTRIP Servers<\/a> are typically GNSS reference stations of various quality levels with a thin layer of software to connect to and push data out to a Caster over an internet connection using HTTP.\u00a0 These days, most GNSS devices intended for use as reference station have the NTRIP server functionality built directly into them. Many lower cost GNSS devices do not provide this ability, but can use SNIP<\/strong><\/span> to connect directly with either serial or TCP\/IP links.<\/p>\n

If you have corrections from a GPS \/ GNSS device you need to share with others, then use SNIP<\/strong><\/span>.\u00a0 If you need to turn a low cost device such as uBlox into an RTK Base Station, use SNIP<\/strong><\/span>\u00a0 (and buy a good antenna<\/a>).\u00a0 If you need to have multiple users connected to your state run CORS account, use SNIP<\/strong><\/span>.\u00a0 SNIP<\/strong><\/span>‘s free community Lite<\/strong><\/span><\/em><\/a> model is the most popular way on the planet to operate your own NTRIP Caster.<\/p>\n

The data format exchanged by NTRIP<\/a> is normally RTCM SC104<\/a> messages.\u00a0 Rev 3.x is by far the most common for RTK uses,\u00a0 while Rev 2.x is used for more primitive DGPS code correction applications needing only sub-meter accuracy.\u00a0 It is also fairly common to use proprietary message formats over NTRIP as well.\u00a0 NTRIP and SNIP<\/strong><\/span>, are more or less agnostic to the message content they relay.\u00a0 However, SNIP<\/strong><\/span> has several integrity monitoring tools built-in for RTCM 3.x message content use.<\/p>\n

Typically the NTRIP Clients<\/a> are GNSS rover devices in the field with a thin layer of software to connect to the Caster and to feed the resulting data stream directly into the GNSS device by way of a serial port.\u00a0 In more advanced GNSS devices, this software is built directly into the rover.<\/p>\n

Need an NTRIP Caster?\u00a0 We suggest you use SNIP<\/a><\/strong><\/span>.<\/p>\n

Need an NTRIP Client? Here is a list<\/a> of popular software.<\/p>\n

Need to see and decode the RTCM3 messages? We suggest you use SNIP<\/a><\/strong><\/span>.<\/p>\n

Need to send your corrections to a public NTRIP Caster for others?
