There is no one in our customer base that have tried this platform. One of our ENG is looking into options and I will get back to you by tomorrow (U.S.A time) THU with an answer.
Currently, our system does not output the $PSIMSSB messages. Adding this capability to the ROVL receiver output would be complex.
We have been in contact with Olex recently, and perhaps they would be willing to make a piece of middleware to create the $PSIMSSB sentence based on the data that the ROVL outputs. But that is not our decision.
We will keep you informed if anything changes on our side.
