Hi folks,
New OpenCPN user here. I used
Nobeltec 8 for many years. But, now I need to upgrade my WinXP to Win7 and found that
Nobeltec will not just copy over (and is no longer supported). So, I found OpenCPN and am impressed so far.
I have to admit that I'm not a boat owner. Instead, I'm an
engineer that performs testing/research involving boats and ships. I use these
navigation tools to prepare and
monitor experiments. I need to request a boat or ship to follow a prescribed
route. I'll telemeter the ship's
GPS to my shore station in order to
monitor their position (use OpenCPN to display telemetered GPS).
So far, I only see one missing feature for my purposes. I bring this request up because I suspect that other folks might also make use of this feature:
I would like to be able to display range rings associated with a waypoint. Just like the range rings associated with the own-boat, I would like to define the number of rings and the radius spacing.
I use this often when I want to define equal length tracks centered on a specific waypoint (for my purposes, I need to see the boat at different angles... but I don't want the boat drifting out of my field of view). The waypoint is my primary measurement point. I place start/end waypoints along the range rings to show the
captain the desired routes (look angles). An inner range ring is good for slow speeds and outer rings
work for higher speeds.
I hope this makes sense... thanks
