	It should be noted that BeiDou-1 is based on GEO communication satellites for the Radio Determination Satellite System (RDSS) [[BeiDou Services\|service]]. User position is obtained through the following steps:
	* the station sends a signal to a set of users through one of the GEO satellites;
	* the user sends a signal to the GEO satellites (at least two of them);
	* each satellite sends the accurate time of arrival of the signal to a ground station;
	* the ground station computes the user position and sends this information to the satellites that broadcast the position back to the user.

	In addition, the system supports a short message communication service that can be exchanged between the station and the users.		In addition, the system supports a short message communication service that can be exchanged between the station and the users.
