LIV4F RTCM input setup

[MHoll.2]

I'm new to the LIV4F (I have a Teseo-LIV4F evalution kit), coming from u-blox.

We have an NTRIP Client who delivers RTCMv3 data to the serial Port of the LIV4F, but the data seems to be ignored (the same data with a u-blox ZED-F9P is working fine).

Do I have to enable the receiving of RTCM data in the LIV4F?

LIV4F cannot use RTCM NTRIP RTK data and provide you a precise fix. LIV4F can output RTCM measurements for a host running RTK engine. This host can use NTRIP data and LIV4F measurements to provide precise position.

However, LIV4F can accept corrections RTCM MSM1 corrections data from NTRIP and provide a few decimeter level accuracy.

To accept MSM1 corrections in RTCM, program LIV4F with firmware with MSM1 tag.

Hi GalaxyQuest,

I got it working with the dedicated Firmware ( long time deviation standard as expected about 0.5m).

Can You confirm that the requested messages are:

RTCM1071 (MSM1 GPS)

RTCM1081 (MSM1 GLONASS)

RTCM1091 (MSM1 Galileo)

RTCM1121 (MSM1 BeiDou)

RTCM1006 ( Station description with Antenna Height) or RTCM1005 (Station description)

is there any possibility that in future the LIV4F will support MSM4 or MSM7 as stated in the data sheet (chaper 3.3 on page 7)?
