The problem of determining the geographical coordinates of the wireless unit in the presence of a decentralized network of airborne navigation receivers on some other sites is researched. Similar solutions for locating a subscriber to GSM is considered, its shortcomings is revealed. A mathematical apparatus for the relative navigation based on multilateration is offered. An experiment to determine the geographic origin and the comparison of its results with the calculated data is carried. Considerations to restrict the mobility of nodes in different variants of the construction of the network is formulated.
