PFAT: Use with Lite models of SNIP

The PFAT feature provides a number of proprietary methods to control the Base Station Data stream content sent to your end users (NTRIP Clients).  Using PFAT, a single data stream can be replicated in several ways, with different message contents and a different frame of reference.   SNIP is the only NTRIP Caster to provide such features.

The PFAT features are enabled during the initial evaluation period for SNIP.   When you register SNIP, the resulting set of product features depends on the license model you select; ranging from our Lite (free) models to our professional grade Pro models of SNIP.  You can upgrade at any time.

Small Networks

If you are running a small network with the free Lite model of SNIP, the PFAT features are not enabled for use.  It is likely you can simply control the GNSS devices which make up your network and achieve many of the same things. You can upgrade your copy to a Basic model at any time should you need to use PFAT or any of the other paid features.

Basic Networks

In the Basic model of SNIP, the PFAT features are fully enabled for use on up to three streams at once.  Using the PFAT features on additional streams required upgrading to the Pro model.

The number of PFAT functions which are performed on each stream are not limited or counted.  For example, one might set up a Base Station stream to: parse the stream, filter to remove unwanted message content, add content from another steam (such as precise clock source), then translate the transmitted ECEF value to another datum, and and finally express the a source MSM 1077 style message as a 1004 style message to support older GNSS devices.  So this example would represent one use of PFAT.

Pro Networks

In the Pro model of SNIP, there are no limits or restriction on the use of the PFAT features on any streams.

  • Shift multiple Base Stations from multiple mixed datums to a common system
  • Remove Ant Ht values so all uses get MT1005 coordinates
  • Remove unwanted GNSS data types from the data stream
  • Assert ADVNULLANTENNA on Base Station Details
  • Etc.
