6 years ago The main thing is to have a more or less continuous signal coverage. As I did. I took a map of Kerbin drew a circle indicating the approximate range of signal reception and scattered stations on the entire surface. I also took into account the possibility of good navigation at points of interest, such as KSC, an airfield on the island and anomalies on Kerbin. and of course, the station should be located on land ;)
Further, it is a good idea to provide a good signal coverage and good informativeness for returning to orbit on the Shuttles. I created a system for stock games and therefore placed quite a few stations close to the equator. (NavAids 1,2,4,7,9,10,16)
for a convenient initial approach to the aerodrome, you can place a couple of stations of any type approximately on the axis of the runway. in the stock game, the airfields are located on the shore, so I managed to place only one such structure ("BAKOR" NDB)
after I roughly outlined the positions of the stations, I opened the map of Kerbin and determined already the most accurate location of the stations, trying to place them on the hills in order to increase the range of signal propagation. I put the cursor in the right place and kept the exact coordinates and height.
to create accurate maps of aerodromes and RWYs I literally crawled every square meter of the territory. I made two special "geodesic" rovers to obtain the exact coordinates, heights, distances and directions. and I have made hundreds of screenshots from different heights, and then stitched them together to render accurate vector map in the correct scale. It took a very long time.
After all the preliminary work was completed I began to come up with the procedures for approaching and landing. I decided not to complicate ILS systems and made a simplified all-in-one facility. in reality, the ILS consists of a whole complex of structures, located in different places on the airfield, but this will complicate the implementation of such a system in the KSP too much. so I located the "virtual" navaids right on the runway in the center of the Touchdown Zone (TDZ)
these structures provide GlidePath, NDB and DME signals, and lead to an "ideal" point of contact.
Here is the propagation pattern of the GP signal
All that is required of the pilot is to get into the beam of this station as early as possible and align the aircraft along the RWY
Next, I compiled a diagram of the vertical approach and landing profile
in the development of my procedures, I tried to follow the real rules and recommendations that exist in real life. I learned a lot of ICAO documents, training articles and videos on Youtube, learned to fly on the MFS X. studied many ICAO and Jeppesen charts
As you probably already understand, this is a very extensive topic and it will be better if you ask specific questions about your project and try to help you as far as I can :-)

Hi Alexustas thanks for your great job first of all.
just a quick question: is it possible to get some insights/docs about the logic behind the creating navaids for KSP. I just started a new game with Glileo mod and thinking of creating something similar (base on your work if it's possible by licence) as you did for KSC - ILS, VORs,DMEs... its getting more interesting with Kerbal Konstruct with multiple RNWs
i'm not a pure programmer but some basic knowledge. and familiar with .cfg files
looking forward to hear from you soon Cheers Ivan
