As stated, it is a satellite program I wrote. The decay prediction is not very accurate, worst with satellite such as Molniya. The data is used in the prediction to sometimes prevent unnecessary calculations. I have this item on my list of future improvements when time permits. Efforts are taken presently to add LX200 and other goto scopes tracking capabilities. I am beta testing these functions. If someone wish to contribute to the free program's improvements, you are welcome to help. Denis Fco.
