| titleOfInvention | Iso-phase position determining system |
| abstract | The following specification discloses an iso-phase position determining system for locating the position of a mobile receiver with respect to three transmitters. The center transmitter frequency is slaved to the other two transmitters such that its frequency is equal to F1+N/M Delta f wherein N and M are integers, F1 is the frequency of one of the other two transmitters and Delta f is the difference in frequency between the other two transmitters. The mobile receiver is equipped with apparatus to phase compare the various signals from the transmitters in such a manner as to locate the position of the mobile receiver with respect to a family of iso-phase contours defined by the relationship |
