MpcReader retrieves comet and asteroid orbital data in MPC format from the web and store it on your computer in different formats. The data is fetched from the MPC. The main job of MpcReader is to convert plain MPC data to the format needed for KStar
Sight Reduction for Air Navigation with Python
This Python TK application calculates a good set of stars for a 3 star fix, makes all calculations similar to the FAAs Celestial Computation Sheet (see FAA doc FAA-H-8083-18). Also, you can create a PDF file that generates Pub 249 Vol 1 for any epoch you specify. The PUB249 as PDF is found under "Files". I wrote this for my aircraft bubble octant :-) It is mainly useful for air navigation as it assumes a bubble sextant but may be used for normal sextants as well. Requires Ephem and ReportLab (optional for PDF output) Not to be used for real-world navigation!
