VRS³Net software, version 1.4.6
This patch for VRS³Net contains all changes since version 1.4.0. The following document gives you an overview about the changes. 

NTRIP Caster
The handling of connecting an NTRIP server to a mountpoint has been improved to better establish the connection.

Reference data shop module
The reference data shop module has now an improved LLI flag handling when generating data files.

RTO Module
Real time data corrections streams have been improved to handle reference positions of 90° longitude.

VRS³Net software, version 1.4.5
iScope
The communication between the rover information and the data base has been optimized, so that the NMEA strings will be written much faster into the data base.

ITRF2008 support
VRS³Net now offers ITRF2008 as an additional reference frame. In addition ITRF2008 is now internally used as the reference frame for the transformation into ITRF current epoch.

The usage of ITRF2008 as basis for ITRF current epoch calculation includes a multi-step transformation approach, which again offers ITRF97 as a reference frame.

Reference Data Shop
The reference data shop has been improved to ignore invalid ephemeris files when scanning the files for an order. In case of invalid ephemeris files, those files will be ignored and the observation data will get delivered in the order.

RTCM3 decoder
Improved RTCM3 decoder now correctly decodes Glonass ephemeris data.

RTO module
Multi-threading support
The RTO Net module now offers multi-threading functionality within its properties. Multi-threading allows to spread the load for the generation of the correction data over multiple cores of your server hardware to improve the performance of the RTO Net module when providing VRS data streams and to allow more user connections at the same time. The default value of threads is 4. 
Please note: The value of worker threads needs to be configured depending on the number of CPU’s available on your machine. It should always be smaller than the overall number of available CPUs.

When updating your VSR³Net with version 1.4.4, multi-threading is automatically activated in your RTO module. The number of worker threads is set to 4. In case your system has 4 or less CPUs, please remove the RTO module, re-insert it again and change the value for “Number of Worker Threads” according to your hardware.

Check of data delay
In addition to the multi-threading, the RTO module also offers a property to check the delay of the data compared to the server time. In case of a delay bigger than the threshold, the RTO module gets unhealthy.

Please note: Due to the changes in the RTO module and the availability of new information in the different views, the software automatically resets the layout and will start again with an empty screen. Please set your layout again after the restart of the VRS³Net UI.

Storage Integrity with NetR3
The storage integrity functionality in combination with a NetR3 receiver has been improved to now also support the additional satellite system when downloading the internal data files.

Web Application Advanced – Session Overview and Session Details Report
The two reports in the web application advanced have been optimized to correctly show the session information in both reports for a huge amount of data.

VRS³Net software, version 1.4.3
BINEX decoder
The improved BINEX decoder can now handle BINEX data streams from NetR9 containing the maximum number of tracked satellites.

Network Processor – new processing mode
New option “SparseVRS” added to the VRS³Net processing modes. SparseVRS allows setting up a sparse VRS network for applications with sub 10cm horizontal accuracy requirements. Please contact Infrastructure_Support@Trimble.com for details regarding specifications, requirements, setup and potential applications.

NMEA output in Integrity Monitor Module
The NMEA output is now using an improved position converter for positions close to the equator. 
Interval and NMEA type properties are now applied correctly.

NtripCaster
Improved NtripCaster is now correctly detecting the type of incoming requests (NtripServer/ NtripClient) when the mountpoint name contains certain strings.

Raw Data Analysis
The raw data analysis in the GNSS receiver module has been improved to contain an analysis for ionosphere scintillation. 

Reference Data Shop
Improved file scanning process leads to better performance. File scanning now consists of two coactive modes: Full mode and Quick mode.
-	When in Full mode, the module scans the whole folder tree recursively starting at the root folders that are configured in the module properties. The Full mode scan is performed once (nightly).
-	When in Quick mode, the module scans only active folders, that is, folders in which files have been created during the last 48 hours. The Quick mode scan is performed in regular intervals during the day and takes a few minutes to complete. For configuring the interval, one uses the module property “Time to wait between scans”.

RINEX Storage
Improved RINEX storage module auto-corrects false spacing information in the header section. The line “TIME OF FIRST OBS” did show an incorrect number of spaces between the time information.

RTK on Demand
The RTK on Demand functionality was temporarily disabled and has been re-activated again.

RTO Module
Communication overhead significantly reduced due to improved communication between VRS RTO modules and the VRS³Net UI.

Storage Integrity
Storage Integrity is now more robust and stable as it has been modified to no longer contain duplicated information in the data file after an interruption during the download. 

VRS³Net software, version 1.4.1
Frame transformation parameters
The frame transformation parameters file has been updated to represent the latest published transformation parameters for the GDA94 coordinate system (in Australia).

GNSS Receiver Interface
The interface to a Trimble R7GNSS receiver has been changed to now also request GLONASS data from this receiver in active mode.

NTRIP Caster – keep alive setting for incoming connections
The NTRIP Caster module is now offering a Keep -Alive mechanism based on incoming data packages. The Mountpoint property dialog offers a new setting called “Disconnect inactive clients”. A drop down box allows different time intervals slections from “Never” (Default setting) to 90sec. If the NTRIP caster does not receive any data package back from the rover within the defined time interval, the client is automatically disconnected from the system.

Improved Proxy Server handling
NTRIP client connections from GNSS receiver modules now feature improved proxy server handling.
With an activated proxy, Google Maps is now displayed. This feature does not support ping functionality.

Reference Data Shop
RINEX v2.10 data out of the reference data shop has been improved to exclude L2C data in case the source data contains L2C information.

Report Generator
The report generator offers two new reports:
-	Accounting.txt Post Processing – this report summarizes the accounting information for sessions from the reference data shop;
-	Costs per login report – this report provides the sum of costs for all measured sessions over the selected time period. For contract items with flat rate, the full flat rate amount is shown, for contract items with epoch to epoch based accounting, the sum over the measured epochs I presented.
The accounting.txt report has been modified to show the full configuration name of the RTO module.
