Errors in the Coordinated Universal Time (UTC) offset parameters broadcast by Global Positioning System (GPS) satellites caused many thousands of GPS-controlled clocks to be in error by approximately -13 μs on January 25-26, 2016. The erroneous UTC offset information was broadcast by 15 GPS satellites, or half of the available constellation, during the anomaly. This paper discusses the technical reasons for the UTC offset anomaly, its effect on clocks controlled by GPS satellites (hereafter…

Urban GPS Integrity Monitoring Using a Graph-SLAM Framework
This work proposes a graph-based Simultaneous Localization and Mapping (SLAM) framework to perform receiver Integrity Monitoring (IM) as well as multiple GPS Fault Detection and Isolation and demonstrates that this algorithm performs robust integrity assessment as compared to the conventional IM algorithms.

A graph-based Simultaneous Localization and Mapping (Graph-SLAM) framework to perform multiple GPS Fault Detection and Isolation (FDI), in particular, satellite faults due to broadcast anomalies and received signal fault due to multipath is proposed.
Asynchronous WAM with Irregular Pulse Repetition
The article presents the principle of operation and equations for calculating the coordinates of an aircraft in an asynchronous multi-lateration system, together with the results of a computer simulation allowing comparison of the accuracy of position estimation between the asynchronous and the typical, synchronous MLAT.


GPS Receiver Impact from the UTC Offset (UTCO) Anomaly of 25-26 January 2016
It is described how the existing interface specification provides sufficient information to detect the non-conforming data such that receivers can protect against such faults in the broadcast data.
The SIM Time Network
This paper provides a brief overview of SIM and a technical description of the SIMTN, and presents international comparison results and examines the measurement uncertainties and the metrological benefits that the network provides to its participants.
