E-OTD stands for "Enhanced Observed Time Difference," which is a technology used in navigation and positioning systems, particularly in the context of mobile communications and location-based services. It enhances the traditional observed time difference (OTD) method by improving the accuracy of location determination through the use of multiple reference points or base stations. In E-OTD, the location of a mobile device is determined by measuring the time it takes for signals to travel from several base stations to the mobile device.
