A Joint Positioning Algorithm of TOF and TDOA Based on Weighted Centroid [PDF]
Aiming at the problem of low accuracy and positioning divergence in the UWB TDOA positioning mode with the positioning scenarios such as severe noise environments or tags near the base stations, a new TOF and TDOA joint positioning method was constructed

Initial Relative Orbit Determination Using Heterogeneous TDOA [PDF]
This paper presents a solution for the initial orbit determination of a space-based RF transmitter using time-difference-of-arrival (TDOA) measurements obtained from space-based receivers in known orbits. Orbit determination requires six independent TDOA

A New Method of D-TDOA Time Measurement Based on RTT
In this paper, a novel difference-time difference of arrival (D-TDOA) time measurement method based on round-trip transmission (RTT) is proposed. The accuracy of time measurement is critical for high accuracy positioning, yet the traditional time ...

A two‐stage iterative method for short‐wave source localisation
Short‐wave source localisation has an important role in many fields. A two‐stage iterative algorithm is proposed based on the ionospheric virtual height (IVH) model using the direction of arrival (DOA) and time difference of arrival (TDOA) measurements ...

A Model on Indoor Localization System Based on the Time Difference Without Synchronization
Localization has emerged as an attractive solution to enable new business models that rely on location-based services in wireless networks for communication, sensing, and control. In particular, time difference-of-arrival (TDOA) is one of the widely used
