Earth Orbit Objects


Earth Orbit Objects is a free program. It was created to predict satellite passes. Included are 3 different displays to show selected satellites. The Globe view displays your selected satellites as they would appear around the Earth,  Sky view on the other hand displays satellites as seen amongst the stars. Predictions and satellites are processed using SGP4 and SDP4 for maximum accuracy. Precision for times and locations are very accurate. Search tools are available to find transit predictions across selected objects, Sun, Moon, and others. Auto or manual download and update of elements using Space-Track (require free account) or Kelso's website files are within the program options. EOO creates prediction of iridium flares for any locations. Resulting tracks can be viewed with Google Earth (must be installed on your PC). EOO was created to be user friendly and therefore easy to master. It provides a highly effective tools to predict, search and observe Earth satellites.

                    Date:  11 January 2014

                    Earth Orbit Objects (Ver. :
   EOO FULL INSTALL                     
                    Remove previous versions prior to installation of version 6.0.0
                    Proceed to "Program Files" and delete the folder "...\Bluewing" if it exists.

                        Changes have been completed to improve the program.
                        The major improvement was the more precise calculations of planets and the Moon position using JPL DE423.
                        The size of the install file has incresased drastically due to the addition of the DE file.

                        Also fixed a small error in the DPG4 codes for calculating deep satellites. Improved analysis seach method to speed up search process.
                        My future intentions are to add the Messier objects to increase position awareness in sky mode and fix the help mode.                   
                        If all goes well and as always time permitting, these changes will be added in the next version.
