Celestial Navigation Plugin Redux

[rgleason]

Harmut I believe I did that this morning, or last night, just scroll up to the most recent one I posted Please. It's gotten better, but some transparency on first screen. (Also I finally was told by Chuck what I was doing wrong with Polars). Need to get some good Noaa Polar files for testing. Some of the Australian ones have a different projection and do not work.

Its working much much better and Sean has made some interface improvements. Thanks for testing!

Tried to compile a release version again, I had downloaded this yesterday too and it appears Sean needs to "fix that isnan thing" as he puts it. Sorry.

Yes weather fax works fine,
i was asking for weather routing see post http://www.cruisersforum.com/forums/...ng-100060.html

[seandepagnier]

ah yes, isnan isinf and NAN all do not work in msvc but I think I have a fix in git now, so it should fix all 3 errors

[rgleason]

Dear Sean, git clone'd and cmake C_n_pi It seemed to fail.
When I ran MSVC++ Opencpn in Debug mode this message:
Failed to load celetial_nav_pi /data/IGRFile.COF ....magnetic data will not be available. (Perhaps I need to copy data again to the build directory? Will try that next, would be user error I think!) I include the MSVC debug and release tlog files for C_n_pi

Also the MSVC Debug and Release build Output files.

Hope it is not too much.

[rgleason]

Well, I guess I should have copied the
opencpn-git/plugins/celestial_navigation_pi/...data
directory into
opencpn-git/build/plugins/celestial_navigation (make a new directory)

I did that and reloaded MSVC and it started "Parsing include files....." running for a very long time with maybe 2700 files or something. Then I noticed that weather_routing_pi was now recognized and tried to compile, is this correct? I thought it would only compile and work properly under seandepagnier/opencpn branch?


Then when I used MSVC to build a Debug version I got the MSVC output attached and celestial_navigation_pi did not complete. Please see attached celest_nav log file too.

[seandepagnier]

the celestial navigation plugin is a separate repository and does not need any special branches or depend on anything special. You do need to copy the data files.

[seandepagnier]

Also, you cannot compile while opencpn is running on windows. You have to quit the program before attempting to compile every time, because they cannot be overwritten when in use. This limitation is windows specific, on any other operating system it would not have caused you any issues.

[rgleason]

Thanks Sean, sorry.
Have tried it all again, making sure on right branch and head.
Removed celestial_naviagtion_pi and git cloned again.
Copied the plugins/celestial_navigation_pi/data TO build/plugins/celestial_navigation FOLDER.
Then built as normally, without MSVC open!

It did not compile I did not find a celestial_navigation_pi.dll with today's date, in the build/plugins/debug directory. Here are the output files and Opencpn.log which might also be useful for weatherfax.

I can get the plugin to run and can input data.
I just can't get it to display any lines of position. Is it me, my system, or a bug?

celestial_navigation_pi.dll is in opencpn\plugins (this is the .dll from post #5. Is there a later version?)
1GRF11.COF is in open\cpn\plugins\celestial_navigation\data
vsop87d.txt is in opencpn\plugins\celestial_navigation\data
celestial_navigation_basics.html is in opencpn\plugins\celestial_navigation\data

I checked the math against my own sunsight spreadsheet (attached); looks to be okay.

I'm running Windows XP sp3 on a Toshiba netbook with OpenCPN 3.2.0

Great, thanks for the report. I think I'm not allowed to divide by 0 in windows.. it works so well in linux. Anyway.. I think I fixed it.. try pulling the new git.. and hopefully it builds in windows.. I'm looking forward to wrapping this plugin up for an actual release soon.

Did you try zooming out really far on the whole earth and looking around to see if there isn't some timezone bug which could potentially exist on only your system and cause the sight to be in the completely wrong part of the world?

Sorry if that isnt the problem. Hopefully soon you can try the new version since the one posted here was old.

[Porthandbuoy]

Zoomed out and found my circles . . . miles from where I expected. The fault was mine however.

A couple of observations:
When editing a sight I am unable to change the date. Time yes, Date no.
My cocked-hat seems consistently east of my position by a considerable margin. Again, this could be me.

I'm looking forward to trying the next build.

( A big thumbs-up for this plug in )

who need celestial navigation "plug in".
that would be the same like someone shagging your wife and you are watching.

use pen, paper and watch or stick to gps.

It's not necessarily a question of 'need', more one of want. After all, why take weeks to sail somewhere you can fly to in a few hours.

I got into astro after spending some time on a jack-up drilling rig firmly rooted to the sea floor off the Tunisian coast. This was at the start of Gulf War 1, and if the GPS was to be believed we were doing 17 knots across the Libyan desert. The American Dept of Defense were dicking around with the GPS satellite clocks.

I use, but don't rely 100%, on GPS. Anyway, it's nice to work up a series of sights and find yourself close to where the GPS says you are.

Then what better then to do it old way. Sextant, pen, paper, watch and here we go.
