Prediction Calculator


Provides a 1 week (7 day) orbit location prediction listing for when the ISS (ZARYA) 25544 satellite is viewable from your location (39.043701171875, -77.4741973876953).




Mutual Window Calculator


Specify an additional grid square or latitude/longitude location and calculate when the ISS (ZARYA) 25544 satellite is viewable from both station locations. This is an excellent tool for radio operators wanting to find when both stations can communicate through the satellite, especially for DXCC and/or S/U/VHF contesting. Currently, calculations are performed for a 1 week (7 day) period for any value above 0° degrees elevation. Only available on website at current time. Does any one want just a general prediction listing for their own location?
