HM Nautical Almanac Office: NavPac

Status of NavPac Software

The release dates of the NavPac version 3 software are given below.

Advisory

Please Note: No attempt has been made to internationalize the NavPac software to deal with other languages, nomenclature and date formats. It should be noted that decimal points are input and indicated by using the period (.) or full stop and that dates (year, month and day) and angles (degrees and minutes) are best separated by a space.

Log of Changes / Bug Fixes

Version 3.1.8

This release corrects the following issues found in version 3.1.6.

  1. Some users, e.g. those from Finland and Austria, whose Windows settings for date formats are not those expected by the software may find that NavPac crashes with an error "Run-time error 13: Type mismatch" before the splash screen appears. This error occurs while the program obtains the current date from the operating system.
  2. Other non-UK users whose Windows settings for dates are incompatible with NavPac may experience some problems when inputting dates and displaying dates. Similar error messages to Item 1 may be seen.
  3. If your system is not connected to the internet and you try to access the NavPac website from the main menu then the program may crash.
  4. When a user clicks on the print button to print the Log from Sights then the program will crash with an error "Run-time error 9: Subscript out of range" if any of the following are not the default values, namely, the height of eye, index correction, temperate or pressure.
  5. In Finder, inconsistencies in displaying the selected way point near the end of the route report and the use of the keyboard to move up and down the list of way points have been corrected.

Version 3.1.9

This release addresses and corrects the following issues found in version 3.1.8.

  1. In Sights – Astronomical Observations, a fatal error occurred if the New Observations button was selected and the previous observation had not been selected for use, i.e. the tick box (Use/Ignore Sight) to the right of the Enter button had not been selected so that the information produced by NavPac, in the right box, was still printed in red.
  2. In Sights – Astronomical Observations, a fatal error occurred if users happened to select an object by clicking on its symbol in the Sights – Astro – FindIt, altitude/azimuth diagram.
