ETA to next waypoint and steer error #77

Closed Techstyleuk closed 3 years ago

Techstyleuk commented 3 years ago

eta.js

I would like to add 'eta' to next waypoint to derived data. this file creates: 'navigation.courseGreatCircle.nextPoint.eta' and delivers a date/time of arrival at the waypoint

steer_error.js

this file adds a few phrases for Steer Error, this being the difference between the desired direction and the actual direction. there are 3 different phrases:

"navigation.courseGreatCircle.nextPoint.steerError" - this gives a value for the error with a positive or negative to suggest the direction "navigation.courseGreatCircle.nextPoint.leftSteerError" - this gives a value for the error in the Port direction "navigation.courseGreatCircle.nextPoint.rightSteerError" - this gives a value for the error in the Starboard direction the right and left steer error are for use to help with clear race displays to help a crew member get clear direction in the heat of a race

for examples of these being used in KIP please see:
