AstroCalc is ment as the amateur astronomers pocket book, containing everything you need to plan a night watching the sky.

Currently AstroCalc can show the position of the Sun, Moon and planets graphically, show set and rise time, magnitude and distance from Earth, and date for next new and full moon.

The graphic display are divided into two sections: A half circle showing the vertical position of the object and a full circle showing the direction of the object.

Please remember to select 'Get position from GPS', otherwise you will get the object data for a position in southern Denmark ;). 'Get position from GPS' samples the GPS position until it has your position with sufficient accuracy, and stores the position for future use. While the position is sampled, an GPS icon are shown in the upper right corner of the screen.

This is an early version, so if you have ideas or wishes, feel free to contact me either here, or on



Application versions: 
astrocal-1.1-1.armv7hl.rpm231.45 KB01/07/2014 - 14:36
astrocal-1.3-1.armv7hl.rpm251.38 KB01/02/2017 - 22:52

- The app was using the system icon for gps when searching for the current position, this icon has been removed at some point, causing the search to fail. New icon has been added.
- Drawing of the halfcircle and circle on the main screen has been ajusted and should now be compatible with both Jolla 1 and Jolla C.
- I believe the problem with rise / set time in 1999 (null date), now really has been solved.
- A problem with wierd rise / set dates around last / first day in the month has been solved (related to the one above).
- The installation now should install the QtPositioning for QML if it is missing.
- Some debug code, left in, resulted in wrong planetary positions in the graphics, the textual information was correct. May be from experimentation and was probably not in the last release.
- At some point the update timer for the main view had been disabled. May be from experimentation and was probably not in the last release.
- The cover page is updated once every fifth minute, changed form once every half hour.
- A green horizont line has been added to the halfcircle.
- A red line in the halfcircle now indicates the vertical position of the object.
- Some simple help test has been added to the about page.

Tried to update from 1.1-1 to 1.3-1 on Intex Aqua Fish but it said "Installation Failed".
I now find that 1.1-1 now just displays a white screen.

Any ideas?

Hi Mick

It would seem that the failed installation has overwritten something.

Try and uninstall v. 1.1-1, and then install 1.3-1, does that help?

Else try and start AstroCalc from a command line, just write astrocal and press enter, does that give any error messages?

When running from command line I'm still getting a white screen and terminal is reporting:-

[W] unknown: 37 - file /// usr/share/astrocal/qml/astrocal.qml:37:30: Type FirstPage unavailable

initialPage: Component ( FirstPage { { }

[W] unknown: 35 file: ///usr/share/astrocal/qml/pages/FirstPage.qml:35:1 module "Qtlocation" is not installed

import Qtlocation 5.0

Ok, it semes the change to make the instalation automatically install needed packages has not helped!

You need to execute the following from a command line:

pkcon install qt5-qtdeclarative-import-location

After that you should be able to run AstroCalc.
