Contact Astro Calculator Customer Service

Why should I report an Issue with Astro Calculator?

1. AppContacter will directly Email your issue/feedback to an apps's customer service once you report an issue and with lots of issues reported, companies will definitely listen to you.
2. Pulling issues faced by users like you is a good way to draw attention of DBG Nautical to your problem using the strength of crowds.
3. Importantly, customers can learn from other customers in case the issue is a common problem that has been solved before.

1. This powerful Astro Calculator is a professional and strategic tool allowing you to determine a vessel's position (FIX) based on celestial observations.

2. The Rise Set Times Calculator lets you calculate set, rise and meridian passage times of all celestial objects for a given time and position.

3. The Celestial Calculator determines the geocentric and topocentric coordinates of any celestial body for a given date and position.

4. With the Sight Reduction Calculator we offer you 5 methods to calculate a Line of Position graph with an Estimated Position (EP).

5. The second section deals with Educational tools, for those wishing to study the subject in more depth; theory and full details of the calculations are given based on widely used nautical publications.

6. The first section is about Astro Navigation tools, for obtaining a FIX by just the names of the heavenly bodies, sextant angles and the times of the observations.

7. This allows you to check your manual calculations and searches in the Nautical Almanac, helping you to master Astro navigation.

8. In the Parameters tab you enter the course and speed of the ship, and the last known dead reckoning (DR) position and time. You can save them all.

9. The app, with 2 main sections and a Theory part, uses a modern approach to celestial navigation.

10. Enter the time at which you want to determine the Fix, and almost immediately you will get the result, complete with position circles on the map.

11. Here you will find the Position Fix Calculator and the Rise Set Times Calculator.

1. In practice you always enter Deck Watch Time in whatever local timezone it is in -- NOT UTC.

2. But I had problems with the interface - in the plan tab for a fix the available objects only lists sun or moon most of the time but navigating randomly between different views I can suddenly get the stars to appear as available objects.

3. You should transcribe Deck Watch Time from the watch to the record in its most direct form, which uses LOCAL time.

4. The app should at least have the option of entering in local time, i.e. in the time that the ship's deck watch is set to.

5. So you entered all this data, probably in DWT (because that is what makes sense and that is even what this app labels the field) but you realized too late the time is in UTC instead of local.

6. So you record time in local deck watch time.

7. Unfortunately its choice of "best bodies" seems to be based entirely on their distribution in the sky (I'm guessing -- I can't figure out what's best about them if not that) but, again, that is not how celnav works in practice; in practice you want some combination of distributed at good angles, and also visible.

8. You also should not perform the local-to-UTC conversion when entering data, because that is error-prone (e.g. if the date changes or if you forgot daylight savings or if you added instead of subtracted, or ... so many things can go wrong).

9. The "Plan" stage gives you something like a prediction of what bodies will be where at a time of your choosing.

10. Also the time to enter here is (once again) in UTC.

11. Really fun tool for looking up celestial objects or navigating by them as well.This takes a bit to get used to but once you understand it, it is incredibly useful and even shows the calculations so you can use it as an effective training toolvery good app .
