On the Geolocation Bounds for Round-Trip Time-of-Arrival and All Non-Line-of-Sight Channels
The development of future geolocation systems requires a fundamental understanding of the importance of various system parameters, such as the number of sensors, the SNR, bandwidth, and channel conditions. We consider the bounds on time-based geolocation

Constrained Weighted Least-Squares Algorithms for 3-D AOA-Based Hybrid Localization
Source localization with time-of-arrival (TOA), time-difference-of-arrival (TDOA), time-delay (TD), received-signal-strength (RSS), or angle-of-arrival (AOA) measurements from several spatially distributed sensors is commonly used in practice.
