The first overseas Glonass ground station for differential correction and monitoring to improve the navigation system's accuracy is due to be launched in Brazil on Tuesday, the Federal Space Agency announced.
"On Feb. 19, Russian Space Systems will launch a ground station for differential correction and monitoring of Glonass in the capital of Brazil. This station will be the first point of correction in the western hemisphere and will significantly improve the accuracy of Glonass navigation signals," a spokesman for the Federal Space Agency told Interfax on Tuesday.
In Russia, such stations ensure accurate positioning in the northern hemisphere. Further stations must be built to improve the accuracy of Glonass in the western hemisphere, the spokesman said.
Russian-built Glonass is an alternative to the widely used GPS navigation system.
