The invention relates to a method for determining the position of an object to be searched for. The method applies a receiver (RX1) for the object to be searched substantially in the vicinity of the object to be searched, a receiver (RX2) for a searcher, with respect to which the position of the object to be searched is determined, and satellites (SV1-SV4) from which a code-modulated random spectrum signal is transmitted, and positioning data of the satellites are determined. In the method, a default position (└{circumflex over (x)}S,ŷS,{circumflex over (z)}S,{circumflex over (t)}S┘) is determined for the receiver (RX2) of the searcher; pseudo ranges (rhoi1) to at least three satellites (SV1-SV4) are measured on the basis of signals received from the satellites in the receiver (RX1) of the object to be searched; pseudo ranges (rhoi2) to at least said three satellites (SV1-SV4) are measured on the basis of signals received from the satellites in the receiver (RX2) of the searcher; and at least the direction and distance (└DELTAx,DELTAy,DELTAz,DELTAt┘) of the object to be searched from the receiver (RX2) of the searcher are determined.
