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 GNSS coordinates based on the latest available satellite signals, 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 Altus NR3 base station and a second roving antenna. 

Contact our team to find out how we can help you obtain the accurate and consistently reliable measurements you need to make your next surveying job a success.

Altus NR3

The Altus NR3 combines easy-to-use, multi-frequency, quad-constellation RTK with an unrivalled communications toolset for a successful survey or GIS project every time.



High-performance, ultra-low power and smaller than a credit card RTK receiver. The AsteRx-m2 sets the standard for reliability and power consumption.



The AsteRx-m2a is a smaller-than-a-credit-card Heading and RTK receiver. It is ideal for UAS, INS integrations and other industrial applications that require high reliability in positioning combined with low power consumption.


AsteRx-i S

AsteRx-i S processes high-quality data, from the single or dual antenna multi-frequency AsteRx GNSS receiver with IMU measurements to generate an accurate and reliable position and orientation.


PolaNt-x MF

PolaNt-x MF is a lightweight, high precision antenna for geodetic, survey and machine control applications.


PolaNt* MC

The PolaNt* MC is a lightweight, sturdy high precision geodetic multi-frequency multi-constellation antenna for use in physically demanding applications.



Georeferencing software for centimeter-accurate UAV mapping



PP-SDK, Septentrio's PPK solution, is a professional software development kit that includes all the necessary tools allowing you to incorporate post-processing functionality into your own applications and products.
