Building a DGPS on XM1110

Hi there,

We are trying to build a DGPS on available RTCM service, using XM1110.
(The end application in self-driving agriculture machines, fyi.)

How to get the XM1110 to accept RTCM feed? Do we need to negotiate about a custom(ized) firmware version of XM1110, or is this kind of customized version readily available anywhere?

Any app note or description would be really helpful!

Many thanks,
