sec 0-20-0-0 is somewhat near spawn, i will give a short explaination on how this works if you have more question on how this works feel free to ask. sec sectorID-range-private-planet, the sector id is well. the id of said sector (it would typicly be 3-5 digits), 0 would be spawn the range is how far the sectors claim is in KM private would be if the sector is private or not, 1 being private planet would be if the sector is a planet 1 being it is a planet, if it is a planet range is to be ignored/set to 0 and the entire planet is claimed, if it is not a planet then that means it is range and any planets in that sector are still claimed
having your own sector is perfectly fine as long as your sector has the center pole or beacon on planet, and you are not intersecting with another sector, and you have a max range of 30km, as well it needing a antenna/beacon with (sec 3to5digitID-range-private-planet) make sure your id has not been taken, GPS's would help, only {A31}+ can have private non planet sector's, fiannly your sector must be registerd at spawn have a mod register it for you. you are allowed to have your own station without having to have a sec.
