The ITU Membership considered and approved a package of eight ITU-R Recommendations on radionavigation-satellite service (RNSS) systems as listed below…

Self-learning total stations. Onebutton laser scanners. Calibrationfree, forget-the-bubble GNSS receivers…

With the development of modern Global Satellite Navigation System (GNSS), the accuracy performance of satellite positioning and navigation is obviously improved, which extends the range of applications greatly for the GNSS receivers…

Recently, most of the smart phones come with GNSS device. Owing to this, many GNSS based applications are being developed. Some of the applications, in spite of being free of cost, have full of features…

When we talk about Geodesy/ Geomatics education in the country, people normally relate themselves only to remote sensing and GIS with a vague idea of some Surveying practices included. There is hardly any institution in the country where…

The European system EGNOS (European Geostationary Navigation Overlay Service) provide ranging signals transmitted by GEO satellites…

The analysis of space weather and ionospheric disturbance effects on satellite navigation, its performance and operation relies upon either the identification of the deteriorating conditions and setting up the GNSS…

The geospatial profession is evolving. As seen in other industries, the next wave of geospatial technology innovation will be shaped by big data, cloud computing, Internet of Things (IoT), and the ubiquity of GIS…

A couple of decades ago, it was necessary to collect carrier-phase data with at least two GPS receivers simultaneously within a few hours to make high…

Last year in Android Nougat, we introduced APIs for retrieving Global Navigation Satellite System (GNSS) Raw measurements from Android devices. Last month, we publicly released GNSS Analysis Tools to process and analyze these measurements…
