2.5.2 Modified

Message / Configuration Item	Description / Comment
UBX-RXM-SPARTNKEY	Message 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
CFG-UART2INPROT-UBX	Default value changed from false to true; enables UBX input protocol support on UART2 by default
CFG-QZSS-SLAS_MAX_BASELINE	Default value changed from 200 km to 350 km

3 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

4 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-RXM-SFRBX 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-SPARTN-USE_SOURCE is set to IP and no valid key is available in UBX-RXM-SPARTNKEY
