Improvements

• Increased receiver robustness in southern hemisphere when SPARTN input is provided
• When QZSS L1S is enabled, QZSS L1C/A reports now correct ‘Half cycle validity’ information in UBX-RXM-RAWX
• UBX-RXM-SPARTNKEY can be polled on all ports, not only on UART1
• UBX-RXM-SPARTNKEY can be send at any time to overwrite previously saved keys, without needing a system restart or without needing to wait for previously saved keys to expire
• SPARTN IP stream decryption robustness improvements to ensure decryption is performed only on valid data verified fully as a SPARTN frame

Known limitations

• A receiver moving at very slow speed (less than 10 cm/s) does not update the heading information in UBX-NAV-PVT. The velocity vectors can be used reliably.

• Geofence status pin must not be re-assigned to another pin • If the receiver is configured to output RTCM messages on several ports, the ports must have
  the same RTCM configuration, otherwise the MSM multiple message bit might not be set correctly

• Time pulse can only be synced to GNSS. Configuration items and relevant flag cannot be set to false (CFG-TP-SYNC_GNSS_TP1, UBX-CFG-TP5)

• If the receiver is configured to GLONASS only operation, it cannot get a PPP-RTK fix when using SPARTN corrections

• Static hold mode is unreliable at navigation rates larger than 1 Hz

• Incorrect SBAS pseudo range value corresponding to 4 ms shift may be reported in UBX-RXMSFRBX messages. This can be detected by monitoring the halfCyc flag in UBX-RXM-RAWX.

• Lower navigation rate achievable compared to previous firmware; performance figures available in related Data sheet document

• UART2 may report different UBX-INF-ERROR messages than the ones reported on the other interfaces

• UBX-RXM-COR message does not get output for SPARTN protocol corrections, while the configuration item CFG-SPARTN-USE_SOURCE is set to LBAND

• UBX-RXM-COR and UBX-RXM-SPARTN messages do not get output for encrypted SPARTN protocol corrections, while the configuration item CFG-SPARTN-USE_SOURCE is set to IP and no valid key is available in UBX-RXM-SPARTNKEY

• Encrypted SPARTN protocol corrections received on UART2 are not reported as SPARTN input in UBX-MON-COMMS and UBX-MON-MSGPP, while the configuration item CFG-SPARTNUSE_ SOURCE is set to IP and no valid key is available in UBX-RXM-SPARTNKEY.
