Accuracy Issues with Quectel LC29HAA GNSS Module (Firmware: LC29HAANR11A03S)

Hello bamarcant,
Thank you for quick response.

  1. Antenna Suggestions: We are currently using the H2UJ4U1H2Q0100 antenna. Could you recommend alternative antennas that might improve the accuracy of latitude, longitude, and altitude readings?

  2. Single Band Configuration: You mentioned that “$PAIR104,<DUAL_BAND_Enabled> , single band is L1 only & PAIR066 is limited, prefixed.” Does this mean that if we want to use a single band, we are restricted to the L1 band, and using only the L5 band is not possible? If L5-only operation is possible, could you provide guidance on configuring the module for this?

  3. Manual Reference: You asked which $PAIR manual we are using. We are currently referring to the manual provided with the module. Quectel_LC29H_Series&LC79H(AL)_GNSS_Protocol_Specification_V1.3

  4. RTK/RTCM Mode for Enhanced Accuracy: We understand that RTK/RTCM mode could improve accuracy, but it appears that this mode may not be available on the LC29HAA,
    based on discussions ticket https://forums.quectel.com/t/lc29h-aa-connection-to-rtcm-3-1-base-does-not-update-lat-lon-values-to-1-cm-accuracy/34016
    Could you advise on any additional parameters or configurations that could help us achieve better accuracy within our current setup(LC29HAA +H2UJ4U1H2Q0100 ), given the limitations of this module?

Best Regards,
Abid
