How can I calculate los visibility (LOS Probaiity) for my place (for streets). I want to calculate Line of sight visibility (Or LOS probability) on the streets of my city. I want to calculate LOS probability, which is based on elevation angle. I want to calculate this values when a mobile receiver moves on a street.
It is not clear if you mean Line of Sight visibility between a terrestrial receiver and a satellite? If so, then I can propose to check my work. I have several publications in this field, the latest one is a book: "Satellite Visibility Analysis and Related Applications" published by Shaker Verlag this year. I guess what you are looking for is the long-term visibility ratio (or availability) of the satellite viewed from a ground station. The long-term visibility ratio expresses the percentage of time in which a satellite is visible from a certain ground station. This is basically the probability the satellite is visible from the ground station. It is possible to take into account restriction on minimum elevation angle and maximum slant range if required. You can check these publications on my researchgate page, and you can download them from IEEE or from Shaker Verlag. The book I mentioned also contains a summary of the other research publications related to this field. I hope I could help.
thx you mr. katona. ı mean line of sight probability between a terrestial receiver and a satellite. Which software ı should use? I want tu use matlab software. should you use matlab for me? Where ı can start from ? You have matlab code? thxs to mr. katona.
Currently I have no source code or software available for public use. This may change in the future. Until that, I would propose either to implent the mathematical formulae shown in my book by yourself, or to use a simulator and use the results of the simulator to estimate satellite availability. I'm at your disposal in case of further questions.
mr kantona thx your answers for me. you use skype? ı want to ask more question about my subjects. we can easily talk. Or you use fcebook? can ı add you if you have them.I want to say my aim clearly. First of all, I want to calculate how much square area which I can see from obsevation points in a street. This is related to 3-D geometry. I have 3-B urban information system for my city(only my city centre). I can see and measure buildings dimensions and street dimensions. But ı can't create clearly formulate and model visibiliy(ı can say LOS visibilit probaility) matmematically.. I think that This is about satellite to ground communication subject. I want to do them for my city propagation modelling. The most parameter is elevation angles(from observer to receiver). Clearly, ı want to calculate this probabilities(visibility or LOS) which is based on Elevation angles(from 5 degrees to 90 degrees.)
