Trimble PivotTM Platform, version 4.3.1
This software update for Trimble® Pivot™ Platform (TPP) contains all changes since the release of version 4.3. The following document gives you an overview of the changes.

Trimble Pivot Platform 4.3 Release Notes Update
Trimble RTX Clocks and Orbits bridging has been introduced with Trimble Pivot Platform version 4.3 in August 2019 (see Trimble Pivot Platform version 4.3 release notes). 
It has been mentioned that “Full-GNSS corrections will remain available for up to one hour”. While this statement remains true for GPS, Galileo, BeiDou and QZSS corrections, please note that Glonass corrections would not be available anymore after 30 minutes. Glonass sends new ephemeris information every 30 minutes which will make old ephemeris not usable anymore while other constellations will be bridged for 60 minutes.

Network Processor
The number of fixed satellites in the Network Processor might have decreased to zero over time in network setups with RTCM input data and inconsistent settings for GPS L2 frequency observations. This issue has been fixed. 
Please note: The RTXNet Processor has not been affected by this issue.

Real-Time Output
1)	RTCM message 1033 will be output by default and will not be optional any longer. The property will allow to output either 1033 only or with a respective antenna descriptor (RTCM message 1007 or 1008). This is needed in order to send the physical base station’s firmware version for optimized QZSS L2C phase adjustment handling with RTCM output.  
2)	For optimized QZSS L2C phase adjustment handling, Trimble Pivot Platform version 4.3.1 will include a check on the physical base stations’ firmware version. With Trimble reference stations operating on firmware lower than version 5.43, QZSS corrections will not be sent out. 

Please note: 
-	This applies only to RTCM corrections. CMRx corrections will include QZSS, independently from the reference station’s firmware version. 
-	No implications or firmware version requirements for non-Trimble reference station receivers. 

RINEX Storage
1)	Updating the QZSS L2C phase adjustment handling in the observations, records and header info in order to comply with the RINEX standard. 

Please note: 
-	It is recommended to disable QZSS processing in Trimble Pivot Platform’s post-processing engines if it includes RINEX files that were stored with versions older than 4.3.1.
-	No restrictions for processing with T02 files.

2)	RINEX long name files being created by Trimble Pivot Platform contained the epoch rate in the file name for observation files as well as for navigation files. The file naming for the navigation file will be changed to the more commonly used nomenclature which does not contain the epoch rate. 

Example:	
-	Old (until Pivot 4.3): ZAPR0123_S_20191120000_01D_30S_CN.rnx
-	New (Pivot 4.3.1 onwards): ZAPR0123_S_20191120000_01D_CN.rnx (please note: does not longer contain “30S_” in the file name.

Please note:
1)	Reference Data Shop, Post-Processing Engines, Trimble Online Processing and storage zipping will work with files according to the new naming nomenclature only. 
2)	In case you need to convert to the previously used nomenclature, please contact our Technical Support Team (rtns_support@trimble.com) for receiving a script that can convert from new to old nomenclature.

Trimble Ntrip Caster 
Ntrip client info strings can be more than 100 characters long. However, iScope Live does not allow strings longer than 100 characters and would have created exceptions in previous versions. With this update, strings longer than 100 characters will be cut for the use in iScope Live and will become usable.
