Abrégé

Methods, systems, and computer program products are provided for analyzing a Global Navigation Satellite System (GNSS) receiver. The method includes receiving electronic diagnostic information from the GNSS receiver, the diagnostic information including observations at different times of signal strength of one or more satellites at each point in a visible sky. The method includes building a flat map of the visible sky including a track of the one or more satellites. The method includes calculating, for each point in the visible sky of the flat map, an aggregated signal strength of the one or more satellites over a predetermined interval. The method includes generating a heat map over the flat map of the visible sky and displaying a visualization of a flat heat map.

Methods, time consumer systems, and computer program products for maintaining accurate time on an ideal clock of a timing device are disclosed. The method includes receiving time information from a local clock, a reference clock, and one or more secondary clocks. The method further includes calculating frequencies for the local clock, the reference clock, and the one or more secondary clocks. The method further includes comparing the calculated frequencies of the reference clock to the calculated frequencies of the one or more secondary clocks. The method further includes detecting a holdover and/or a compromise situation based on the comparison. The method further includes syntonizing the ideal clock to one or more of the calculated frequencies.

Abrégé

A method for improving accuracy in the computation of a one-way transfer time between two networked devices. In one aspect, variability in time transfer latency that is caused by cache loading, data structure setup time, and scheduling variability in software is reduced by initiating a first sequence of loading data structures into cache and priming scheduling, and then initiating a second sequence of calibrating the timing of a subsequent synchronization message so that the completion of the first sequence occurs just in time for the reception of the synchronization message. The method is applicable for any network time synchronization protocol, including Network Time Protocol (NTP) and Precision Time Protocol (PTP).
