For some years now, we have been talking about GNSS interoperability. The concept has received so much careful […]
In the mass market, individuals around the world are creating vast quantities of location data and GPS traces using not only GPS, but also Russia’s GLONASS, Europe’s Galileo, China’s Compass, and India’s Regional Navigational Satellite System. The value of this data and the value chains that produce it will increase significantly with an increase in interoperability of these satnav systems. Currently, non-interoperability represents a serious obstacle to the growth of the GPS market.
The most modernized GPS satellites on orbit will broadcast a new civil navigation message (CNAV) on the L2C and L5 signals in April. That’s the plan, at least. An update on the CNAV debate in the United States. Also, summaries of key presentations from the international committee charged with inter-GNSS compatibility and interoperability.
The report of Working Group A on Compatibility and Interoperability, held November 11-13, 2013, in Dubai, United Arab […]
The implementation changes and first live tests of BeiDou and Galileo on Teseo-3 GNSS chips developed in 2013 are covered, bringing it to a four-constellation machine. By 2020, we expect to have four global constellations all on the same band, giving us more than 100 satellites — under clear sky, as many as 30 or 40 simultaneously.
A New Approach to the Design and Development of Global Navigation Satellite SystemsIn this month’s column, a team of authors affiliated with the Galileo project discusses the Interface Communication Modeling Language, an extension of UML that allows engineers to clearly represent SIS interfaces, critical for the design of GNSS receivers.
A comprehensive methodology combines spectral-separation and code-tracking spectral-sensitivity coefficients to analyze interference among GPS, Galileo, and Compass. The authors propose determining the minimum acceptable degradation of effective carrier-to-noise-density ratio, considering all receiver processing phases, and conclude that each GNSS can provide a sound basis for compatibility with other GNSSs with respect to the special receiver configuration.
