Septentrio has entered into a commercial agreement with Sapcorda, a global provider of sub-decimeter GNSS corrections. Through the collaboration with Sapcorda, Septentrio will pioneer an no-hassle corrections integration into a new line of products for the high-accuracy industrial market. These new products will consist of Sapcorda’s SAPA Premium corrections integrated directly into Septentrio’s latest GNSS receiver technology. The result is sub-decimeter accuracy, which is available to users right out of the box. This significantly simplifies the user’s GNSS receiver set-up process and eliminates the hassle of corrections service subscription and maintenance. Such GNSS receivers acquire corrections via internet as well as via satellite broadcast and deliver reliable, broadly available sub-decimeter positioning to high-volume industrial applications. Sapcorda integration program Sapcorda release its SAPA augmentation service integration program on May 14, following the launch of its SAPA Premium service. The integration program targets companies integrating GNSS chips or receivers and looking to enable their systems to perform in high-accuracy mode. The program offers step by step service integration and proof of concept guidance for upgrading the integrators’ GNSS systems to deliver down to centimeter-level positioning accuracy. The program also includes the offering of free service data, used to validate positioning performance on the target application. The program participants also receive commercial support for introducing the correction data on their marketed products. The SAPA service is delivered using optimized data format and can be integrated by modern or traditional high-accuracy receivers compatible with open standards such as SPARTN and RTCM. Sapcorda’s SAPA services are designed to bring high-precision GNSS positioning to mass market, as well as general industrial and automotive applications. The correction data stream is optimized for homogeneous performance and end-to-end data security with continental coverage in the United States and Europe. The service data transmission also provides unmatched low bandwidth consumption, with broadcast transmission via direct IP connection or geostationary satellite signal (L-band). Sapcorda was established in 2017 to provide an open approach to a safe, broadly available and scalable corrections service. By adding Sapcorda’s SAPA service to its corrections portfolio, Septentrio begins offering sub-decimeter accuracy with quick convergence time anywhere in the U.S. and Europe. Autonomous vehicles, robots “This collaboration allows both companies to bring innovative solutions, inspired by the growing market of autonomous vehicles and robots, to the high-accuracy industrial markets,” said Jan van Hees, business development director at Septentrio. “By integrating Sapcorda’s SAPA service into our products, we are completely removing the hassle of managing corrections for the customers. This means faster set-up times and worry-free, always-on high-accuracy positioning throughout the whole receiver lifetime.” “At Sapcorda our focus is on providing a high-accuracy service suitable for demanding applications where both performance and safety is critical. This includes land robots, UAVs, logistic applications and autonomous vehicles,” said Botho Graf zu Eulenburg, CEO at Sapcorda. “Septentrio’s field-proven high-precision GNSS receivers and their focus on reliability and robustness aligns perfectly with our mission and the capabilities of our SAPA services.” This broadens the range of Septentrio’s existing GNSS solutions, allowing the company to serve a wide range of customers with various requirements in terms of accuracy, operation location and scalability.
