Method, system and devices for positioning a receiver

Positioning means for positioning a receiver based on code modulated signals transmitted by a plurality of transmitting units, which code modulated signals are formed by an individual code for each transmitting unit, and which code modulated signals are provided to said positioning means by receiving means of said receiver, wherein said positioning means comprise

• means for performing a correlation of said provided signals with predetermined replica codes corresponding to said individual codes employed by said transmitting units, and for determining, based on resulting correlation peaks, channels potentially formed by a code of one of said code modulated signals;
• means for determining a value indicative of the signal level of each channel for which a maximum correlation peak is obtained in a correlation with one of said predetermined codes;
• and
• means for determining a position of said receiver based on signals of those channels resulting in said correlations in a maximum correlation peak in a correlation with one of said predetermined codes, of which channels the respective value indicative of the signal level exceeds in addition a threshold value.
