3 Improvements and changes
For detailed information on any new messages or protocols, contact u-blox support or see product
interface description.
3.1 Version 21.02
• Feature: Relevant UBX-NAV2-* messages are available including UBX-CFG-NAV2 configuration
group and CFG-MSGOUT-UBX-NAV2-* configuration items. This will enable the support for
dual-band receiver.
• Feature: Display data from UBX-NAV2-* messages in views 'Receiver' > 'Epoch detection' is
available for dual band receiver.
• Feature: Added UBX-RXM-SPARTN message to monitor SPARTN input status.
• Feature: SPARTN protocol reported as a correction source in messages like UBX-NAV-SAT,
UBX-NAV-SIG and reported as an input protocol in messages like UBX-MON-COMMS, UBXMON-MSGPP.
• Feature: Added support for BeiDou SVs with PRN 38 - PRN 63.
• Feature: Added support in UBX-NAV-SAT to report SLAS as a correction source.
• Feature: Added new flag in UBX-NAV-SBAS and UBX-NAV2-SBAS messages as 'SBAS integrity
used' to indicate if SBAS integrity feature has been used by the receiver or not.
• Bug fix: Fixed issue with reading/writing values for configuration items of type I4.
• Bug fix: UBX-CFG-RATE no longer marks invalid input values. Before it would mark
measurement periods and navigation rate values as not acceptable, while the receiver would
accept them fine as expected.
• Bug fix: Fixed issue where in NMEA 4.11 some BeiDou SVs could be misidentified as GLONASS.
3.2 Version 20.10
• Improvement: Changed some ADR/UDR messages from NDA to PUB.
• Improvement: Added protocol version 33 used by ZED-F9R (HPS 1.0) to u-center Receiver >
Protocol Filter > u-blox Generation 9.
• Bug fix: Fixed bug for the u-center crash when NTRIP server/caster is opened.
• Bug fix: Fixed UBX-CFG-NMEA reporting of version number when V4.11 is selected.
• Bug fix: Fixed for crashes when changing GNSS configuration.
3.3 Version 20.06.01
• Feature: Added remaining NMEA 4.11 specific features such as support for QZSS and NavIC
talker/signal IDs in NMEA-GBS and NMEA-GRS messages. Also new child messages added to
all NMEA message views for the fore-mentioned constellations.
• Feature: u-center support for UBX-NAV-NMI.
• Bug fix: Fixed the bug of reporting IMU-mount Alignment Status flag on ESF-STATUS message.

3 Improvements and changesPage 7 of 15
u-center 21.02-Release note
• Bug fix: u-center side panes now correctly show fix information for receivers that only have
UBX-NAV-RELPOSNED output enabled.
• Bug fix: Fixed "Receiver > Protocol Filter" tab, it shows the menu properly when user selects it
for the second time.
• Bug fix: Fixed the NTRIP connection problem.
• Bug fix: Fixed GNSS ID letter (G->Q) in NMEA-GQGSV and fixed QZSS and NAVIC GNSS ID
letters in NMEA-GNGSA which were crossed.
3.4 Version 20.01
• Feature: Added new NMEA SV IDs to support NMEA 4.11.
• Improvement: Replaced data and satellite signal level view with new logic of getting data for
satellites (multi-band) and improved satellite signal history view.
• Bug fix: UBX-CFG-VALGET messages are now displayed when playing log file.
• Bug fix: Fixed crashing of u-center when AssistNow Online GNSS runs in the background.
• Bug fix: Copyright date updated to 2020 in "Help > About u-center..." dialog.
3.5 Version 19.12
• Feature: Added new version of NMEA (4.11) to UBX-CFG-NMEA and to the config item CFGNMEA-PROTVER.
• Feature: Message UBX-NAV-SIG adds support for the prsmooth flag in the Message View.
When the PR of a signal is smoothed, it will show the PPP led and mark it as 'S'. This is similar
to what UBX-NAV-SAT (the predecessor of UBX-NAV-SIG) was already supporting.
• Improvement: A file overwrite warning dialog shows up while overwriting an existing
configuration file.
• Bug fix: Fixed the issue that would crash u-center when protocol version was changed from
menu Receiver > Protocol Filter. Added/fixed generation MA & 9 & 10 protocol filter options.
• Bug fix: Satellite Position view updated to display data from all signals (multi-band).
• Bug fix: Message UBX-ESF-STATUS now shows the correct calibration status for all sensors
even when they are not being used.
• Bug fix: u-center is now prevented from ending up in a "no-response" status if NTRIP connection
is lost, and the u-center window is minimized.
• Bug fix: Sky view updated to display data from all signals (multi-band) and the performance of
Sky view has been improved.
• Bug fix: Fixed returning invalid mountpoints due to case sensitive names in u-center.
• Bug fix: Supported unicode file paths when opening zipped files (ubz, ubx.gz) which now fixed
the Japanese named folder issue.
3.6 Version 19.11.01
• Feature: Added ESF-MEAS latency to chart view and table view.
• Bug fix: Advanced Configuration View is now fixed to also support version 0 of UBX-CFGVALSET and UBX-CFG-VALDEL messages.
• Bug fix: Advanced Configuration View now displays the layer value correctly in the hex view.
• Bug fix: Fixed bug causing the CFG-HW-OSC_TYPE value text to be corrupted in the Advanced
Configuration View.
• Bug fix: Fixed the display of some fields in UBX-NAV-TIMEQZSS message.
• Bug fix: Updated copyright date to 2019 in "Help > About u-center..." dialog.
