I own a hard copy of this one (and don't know the other ones you mentioned). Excellent (and historical) book which describes all navigation subjects from a practical point of view (i.e. not very scientific). Is a standard in itself. Celestial subjects are based on the use of the Nautical Almanac or the Air Almanac. Multi-Year Interactive Computer Almanac and STELLA are just mentioned (STELLA is US Navy's celestial computer program). No other attention for direct computation methods.

I don't know these courses but yesterday I added the e-learning module of Reed Navigation to the Links paragraph of the plugin manual.

Since yesterday to be found in the Links paragraph ;-)

Above, I erroneously mentioned the e-learning site as being from Reed Navigation. It's from Seasources.net (the link to the Nautical Almanac 1994 is from Reed Navigation).

Selecting a sight to see properties goes in revers order:
Vega to Polaris
Polaris to Vega
Capella to Aldebaran
Aldebaran to Capellea
I use Fulst/Meldau Nautische Aufgaben 1968, page 53, #7.
There are smal differences between the solutions of Fulst/ Meldau and OCPN (year 1957
and manual calculation).

Thank you for checking. They are using different calculation methods... Is there any chance you could make a Test sheet with the information to enter, as NAV has done? We will add it to the end of the documentation for others to use.

Thanks.
Rick

Have added four items to Celestial_Nav Tracker
OpenCPN::Tracker pi - Celestial Navigation: Tasklist

Feel free to comment, correct and augment. You can register and then log similar to registering and logging into Edit Docs.

Just noticed Sean updated the plugin with the note "Fix warning"
I don't think he has fixed the Save sight to correct sight name problem.

File Thingie 2.5.7
rguser rgpass
Look in 3.2.2 Win folder
celestial_navigation_pi-1.9-ov3.2.2-c-win32.exe

Gnomon · 10-08-2014, 01:26

Installed climatology.....ov3.3.3-c.
Selecting a sight to see properties goes in correct order now.
Thanks

For the general public, NavPac, the navigation package of UKHO, is not freely available, and STELLA, the celestial package of the US Navy, is not available at all.

However, the Hydrographic Department of The Netherlands owns several navigation packages that are freely available to the general public. One of these is CNAV 4.1, an interactive program for classical navigation computations. This application might be handy to check the calculations of the plugin.

Link: Nautical computer applications | Hydrografie | Defensie.nl

Note: the site language is Dutch, but I think it's clear enough. The CNAV UI is in English.
