ARE WE THERE? In a multi-GNSS world, that is. We’ve asked that question from time to time in this column over the years. So, are we there yet? That depends. One definition of “multi” is more than one.

IT WAS 1999. That was the year when the first mobile or cell phones equipped with GPS became available. Garmin introduced the NavTalk Pilot aimed at aviators and Benefon, a former Finnish cellphone ...

COMPASS uses the Geostationary Earth Orbit (GEO) and Inclined Geosynchronous Satellite Orbit (IGSO) satellites, which are more suitable for regional services. Its constellation is composed of 14 ...

Precise Point Positioning (PPP) is widely used for high-accuracy navigation, but broadcast ephemeris from the BDS-3 system still suffers from hourly discontinuities that degrade real-time performance.

The development of an Integrated Real-Time Precise Point Positioning (InRPPP) system leveraging BeiDou Navigation Satellite System (BDS) B2b, B2a, and B1C services has significantly enhanced satellite ...

These days, satellite positioning systems play a fundamental role in our society. We are constantly surrounded by this technology, and it has been fully integrated into our lives. It has multiple ...

Global navigation satellite systems (GNSS) have transformed numerous precision-oriented industries over the past few decades. Construction, in particular, has greatly benefited from the real-time ...
