Sightseeing in Septentrio’s hometown of Leuven is delightful. The center is a labyrinth of small, picturesque streets with early Renaissance architecture. However, what dazzles the tourist is troublesome for modern surveyors. Both narrow city streets, such as those in Leuven, and tall structures, such as skyscrapers, distort GNSS readings. These faulty results cost time and money as you verify again and again to ensure that you have a correct reading. 

Septentrio’s +GNSS technology, which provides you with modern GNSS coordinates and access to TERRASTAR augmentation correction services, guarantees cm-level accuracy in the streets of Leuven, Paris, New York, and everywhere else. Obtain Real Time Kinematic (RTK) accuracy in any conditions at any time by using an APS-NR2 base station and a second roving antenna.
