PFAT: Legacy to MSM messages
The Legacy to MSM translation is used to translate older Legacy messages to newer MSM style message types (msm = multiple signals messages). This has value to network operators with an installed base of older Base Station GNSS devices which cannot produce MSM messages directly. Caster streams can be developed […]
PFAT: MSM to Legacy messages
The MSM to Legacy translation is used to translate newer MSM style messages (msm = multiple signals messages) to old Legacy style messages. This has value to network operators whose rover communities (NTRIP Clients) contain older devices that cannot process the newer MSM message types. Caster streams can be developed […]
PFAT: Removing L2 content in Legacy messages
The Remove all L2 Observation Content translation is used remove L2 content from Legacy RTCM3 message types 1003~1004 (GPS) and 1011~1012 (GLONASS) to produce (smaller) 1002 and 1010 messages. This has value to network operators whose rover communities (NTRIP Clients) are made up of L1-only devices by allowing them to […]
PFAT: Last Observation Flag
The Last Observation Flag translation is used to adjust the flags present in the RTCM3 messages which are used to indicate (to the rover devices) that the last set of observations at a given common time has been sent. By convention, GPS observations are always sent first, followed by GLO […]

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 […]
PFAT: Adjusting the Datum for a Network
In this article we review the process to align the reported Base Station ECEF locations for a network of six stations to all use a common IGS08 frame of reference. This is commonly necessary when the stations are managed by other parties who have selected another datum for use. The […]
PFAT: Adjusting a Base Station to a Common Reference Frame
How to Adjust a Base Station to a common Reference Frame so the RTCM messages (MT1005 and 1006) use the correct location. See also this article on the Translation of ECEF in a small network. This is an advanced topic and presumes that terms like datum and frame of reference […]
