sat look angle calculator

Post by TPT »

There used to be a good one on-line I can't find anymore. Used google maps, had the right satellites for North America, and showed the direction on the map.

Need to see if we can get SES-11 at our one studio site--may be adding a station & plan using some satellite fed programming. Site wouldn't work for AMC-8 (aimed right into a hill) but we moved a hard-drive fed music station there, so haven't needed anything off the bird except for an occasional special program--which we would feed via Barix from another station.

However, if we get this other station will need to see SES-11. Should work--but would like to see the plot. Unfortunately most of the look-angle calculators o-line are either useless or weird (one came up with a Chinese satellite at 105 degrees--don't think an over-pole path would work well).

https://www.dishpointer.com/ is what I use most of the time. They also have an Android app that uses the phone camera for augmented reality. The online app actually shows the path on google earth and gives a sliding ruler of look angle height AGL as

https://satlex.de/en/azel_calc.html is also pretty good and has an extensive city list. It also shows the LNB skew.

If a Chicom satellite shows up, they probably have the sign of the orbital slot inverted. It really doesn't matter as long as the slot longitude is correct.

One caution that I have to throw out about the Dishpointer (and any other geotech) phone app. It is only as accurate as the phone compass and I have found that the compass can vary 30+ degrees due to nearby metal objects and especially high current power lines.

I use an additional app called SunSurveyor to do a shot of the sun to verify my phone's compass calibration. If the sun is where it is supposed to be, the compass is correct. IF the sun isn't where it is supposed to be AND the compass is correct, we probably got a bigger problem than miss-aiming a sat dish...
