BeiDou Numbering Presents Leap-Second Issue

March 3, 2015By
Leap-Second-O

During preparation of playback scenarios for the upcoming leap-second event taking place in June, engineers at Racelogic identified a potential pitfall for GNSS engineers. The difficulty arises from the fact that BeiDou uses a different “day number” for the date to apply the leap second, compared with GPS and Galileo. GPS and Galileo use 1-7 as week day numbers, and... read more

Successful Testing — and Why It Is More Important Than Ever

March 2, 2015By

By John Pottle and Neal Fedora Precision matters. While “accuracy” is somewhat one-dimensional, “precision” is multi-faceted. We submit to you that whatever area of GNSS-based location you are interested in, precision matters today and will matter more in the future. In this column, we’ll explain why this is. Traditional test approaches involve taking measurements to evaluate fundamental performance, for example,... read more

Multiple RF Output Simulation

March 1, 2015By

Spectracom GSG-Series GNSS Simulators have added capability to provide multiple RF outputs for advanced testing where multiple receivers or antennas are in use in a single system. Typical examples include controlled radiation pattern antennas (CRPA) or heading/attitude receivers and systems. The intuitive StudioView software allows easy reconfiguration of test cases to change the conditions seen by one or all receivers... read more
