There's also a bunch of other ways to calculate it, like in some sort of SK plug-in. I thought the derived-data plugin calculated it, but it doesn't at this time. You could always use Node-Red to calculate it inside of SignalK using ETA and current time to calculate TTG.
As far as I know, KIP only displays data, you'll need to come up with TTG some other way. Derive-data does calculate ETA.
Hi,
Thanks for the help. I am not sure if there is a NMEA sentence for Time to Go or for ETA. I'll check out the derived data plugin. That seems useful.
I suppose for manipulating data there is no escaping Node Red![]()
I'll have to give it some time and learn how to use it properly.
Thanks again, Jodel
Derived Data does calculate it and sends out a SignalK value for navigation.courseGreatCircle.nextPoint.estimatedTimeOfArrival
