GPS signal propagation is delayed by the troposphere compared to free-space propagation.
Unlike the ionosphere, tropospheric delay at the GPS frequencies is not considered …

In this paper, an algorithm for a dynamic base real-time kinematic (DRTK) GPS is presented
and a novel application to the guidance and control of a mobile robot pulling a trailer is …

A strategy to enhance the accuracy of path following for autonomous ground vehicles in a
convoy is presented. GPS carrier measurements are used to estimate relative position with …

A wide-area positioning system, Such as the Global Posi tioning System (GPS), uses a
constellation of satellites to position or navigate objects on earth. Each satellite in the GPS …

A GPS based automated convoy strategy to duplicate the path of a lead vehicle is presented
in this dissertation. Laser scanners and cameras are not used; all information available …

A method for mitigating atmospheric errors in code and carrier phase measurements based
on signals received from a plurality of satellites in a global navigation satellite system is …

A new DGPS data collection system is specifically designed to characterize the tropospheric
spatial decorrelation error (TSDE) over a 5‐km baseline near Athens, OH. In this setup …

In this paper, a new method is introduced to estimate and characterize tropospheric spatial
decorrelation errors (TSDE). Mathematical derivations are provided to identify TSDE on a …

Commercially available global navigation satellite system (GNSS) processing software is
user-friendly and can be used in a wide variety of positioning applications from establishing …

For dual-frequency GPS observables, one of the largest error sources affecting high-
precision positioning solutions arises from the unmodelled troposphere. Even for the short …
