Thanks for the info! I saw your 'Chart Work' page but didn't find any link to download it, I have your manual and GPX file, but where is the software?
I will checkout the other options, thanks for pointing them out.

Regards,
Maarten

I did my home work better and saw that I needed to download it from your website, so that will turnout to be OK.
Nice screen shots of the new program! Do you have any plans to also make something for android? I saw many programs for windows mobile and I am currently using PocketStars for sights, but I am planning to buy a new phone with Android and couldn't find a single one

Chart Work plugin

This is posted in the OpenCPN page:
Chart Work plugin

by Andres - 11/02/2010 - 22:43
If anyone wants to collaborate in developing a "Chart Work" plugin for OpenCPN, feel free to e-mail me.
Firstly, I am thinking in a module as the program "Chart Work.exe" is. Improvements could be implemented in the future.
Thanks!

Re: Celestial Navigation with OpenCPN

Sadly there is no longer an AstroNavgation plugin for OpenCPN as the development has stopped. There is a gpx tool around for Windows but nothing that can be used for Linux. So a while ago I wrote my own simple gpx generator for plotting position lines, by creating "routes".

Name:	astro1.png
Views:	222
Size:	104.2 KB

This illustrates a round of star sights taken from John Letchers excellent old book: Self Contained Celestial Navigation with H.O. 208. (now out of print).

Quote:
./astrolop_0.1.0.rb Version:0.1.0 110320

Useage:
./astrolop_0.1.0.rb lat long azimuth intercept body [1/2 length of LOP default = 10 M]

lat & long is the reference position used to produce the intercept and azimuth.
Normally this is an 'Assumed Position' to fit the tables used.
It could also be the DR position if you use H.O 211 or a calculator.
Use the last argument if the position lines are to short to produce a fix.
The script produces a gpx file named after the body ('body'.gpx).
Import this into OpenCPN wih the Route Manager.
