Smart Satellites Prediction - OKTOFLY.COM
Satellites orbit the earth constantly and their position in the sky is always changing.
Using high-resolution ground elevation data, we calculate the position of each satellite relative to your location, and check the ground elevations around you to determine if those satellites are visible in your location.
In real-time we test thousands of elevation points for each forecast hour, so we can accurately predict safe GPS conditions.
For a full 15-day forecast, we evaluate over a million elevation points around your location!
Our satellite forecast is accurate to +/- 1 satellite over 90% of the time.
