WebMar 26, 2003 · Figure 4: Detailed path geometry from a geostationary satellite to an Earth-based receiver (r = receiver for this figure, R = Earth Radius). Okay, let’s get to it. So, we have a receiver r point at {lat1, lon1} and a transmitter at { lat2 = 0.0 (equator), lon2} and we want to find the azimuth, and elevation (tilt) angle. The azimuth is precisely the same that … WebJun 28, 2024 · The "inverse square" (aka the square root) of (1,600,000,000/0.000003) is 23,000,000. The Sun could be 23 million times as far away as it is and we would still (barely) be able to see it. 8 minutes * 23 million = 185 million minutes = ~350 years. We could still (barely) see the sun if it was 350 light years away.
