SatPC_32bit.zip This is 32 bit version but is also 64bit version available. Just copy the zip file, extrac it in any location and start the program. It is still beta so bugs are possible.

The PC version has several changes: The SGP8 algoritm is corected. Now both algoritms SGP4/SGP8 give consistent results. The small differences are related to the balistic coeficient in SGP8. A new ingine for GPS connection is applied. In space mode now the trajectory of all planets and moon are added. Improvedatmospheric refraction algoritm Added swith for number of calculations per sec. (Alt+f/Alt+g).

Short keys:

Alt+f calculations every 50ms Alt+g calculations every 1s Alt+r refraction on/off Alt+s swith SN/NS
