1. Because of the differences among different effects of radiolocation systems, the GPS and LORAN-C were analyzed as two examples.

2. In short-baseline differential GPS or E911 radiolocation based on mobile communication networks, multipath becomes a major ranging error source.

3. The ship is equipped with a complete set of radiolocation equipment, homing heads and locations stations.

4. In order to improve adaptability and robustness of algorithms, we present another TOA/TDOA data fusion algorithm based on Support Vector Machine Regression for radiolocation.

5. An extended Kalman filtering (EKF) algorithm is designed for radiolocation in cellular communication system, simulation is conducted to examine its performance.

6. Utilizing GSM network, there are many ways to realize radiolocation to the urban taxi.
