comment Free open satellite or other remote sensing data for night time?
for long time series, I am afraid that there is nothing else (to the best of my knowledge). Satellites like ASTER are able to provide nightime images, but this is based on "on demand" acquisition, and usually focusing on TIR (visible artificial light is not as bright as the sunlight, so you need high sensor sensitivity to acquire image at night).

comment Which projection is suitable for the measurements of this great circle?
in this direction, it should be an ellipse, not a circle, because the Earth is flattened. It is approximatively 40008 km

comment How to draw a map of postal codes of a country?
have you looked at gadm.org ? but I am not sure that administrative boundaries will match your postal code. Anyway, in your case, it would be better to ask two questions: first, where to find the data (there is a "data" tag), second on how to use the data (after trying with, e.g. QGIS)

comment How to draw a map of postal codes of a country?
welcome to GIS SE. Could you please be more specific about the type of map that you want : is if for printing or for displaying on the Web ? Also, do you have any constraints on the use of a software ? Basically all GIS software can do what you want, so the question is too broad. May I suggest that you try with QGIS software and edit your question if you have more specific problem ?

comment Visibility analyses of two objects with ArcMap?
thank you for your feedback. It would be even better if you could put it as an answer if you solved your problem (and accept it after 48 h to show that it has been solved). I would also be interested to know why my method didn't work for you.
