Company: ANAVS GmbH
Advanced Navigation Solutions - ANAVS, based in Gilching and Munich, Germany, is a leading company in the research and development of future navigation systems with Galileo and GPS signals. ANAVS is known for its accurate and reliable attitude determination systems, and offers related hardware and software for both automobile and maritime applications. We perform sustained research, and develop and implement leading edge technologies such as triple frequency RTK and PPP with reliable integer ambiguity resolution. Our partners and customers benefit from our capabilities in simulation, rapid prototyping, testing and implementation.
Galileo and GPS satellites transmit code and carrier phase signals that can be used for positioning. Low-cost receivers use only the code signal, and are thus accurate down to a few metres. Geodetic receivers, meanwhile, use the carrier phase, which offers millimetre-level accuracy. However, the carrier phase is ambiguous and even most advanced GNSS receivers resolve these ambiguities with a poor failure rate of a few percent. This is far in excess for safety-of-life applications.
ANAVS´s new receiver system achieves centimetre-level accuracy by resolving the carrier-phase ambiguities with an error rate of less than 1e-9, which is several orders of magnitude lower than in any existing technique.
Project: A differential Galileo/GPS receiver systems
Carrier phase differential GPS (CDGPS) is a widely used system for relative positioning. However, the carrier phases are periodic and require an ambiguity resolution which can be performed today only with a failure rate of a few percent due to the small carrier wavelength. This is far too much for safety of life critical applications.
ANAVS GmbH is developing differential Galileo/GPS receiver systems with a new integer ambiguity resolution technique that uses soft baseline constraints and multi-frequency code carrier combinations.
It enables a failure rate of less than 1e-7, and can be used for a wide range of applications including freight stabilization of cranes and helicopters, navigation of trains and ships, for attitude determination systems, and bridge constructions.
From space to industry
ANAVS GmbH is providing a downstream application for Galileo and GPS: It develops the first differential receiver system that achieves a centimetre-level positioning accuracy and an ambiguity resolution with a failure rate of less than 1e-9.
The receiver system fully benefits from the new Galileo signals with their large bandwidths, additional frequencies and BOC modulation. The new receiver algorithms are protected by several European and US patents.
ANAVS GmbH is having its headquarters at Oberpfaffenhofen and is supported by the European Space Agency and the Bavarian ministry of Economy, Infrastructure, Traffic and Technology.
ESA Business Incubation
The founders of ANAVS GmbH Patryk Jurkowski and Patrick Henkel were the Bavaria Regional Winners in the European Satellite Navigation Competition 2010.
Patryk Jurkowski is a master student in electrical engineering and information technology at the Technische Universität München, Germany. He recently finished his bachelor thesis on ‘Baseline constrained ambiguity resolution with multiple frequencies’ with distinction. Patryk worked as a student trainee on EGNOS performance and integrity - level B for Galileo at EADS Astrium from 2006 to 2010.
Patrick Henkel studied electrical engineering and information technology at the Technische Universität München, Munich, Germany, and the Ecole Polytechnique de Montréal, Canada. He received his diploma in 2005. He then started his PhD on reliable carrier phase positioning and graduated with summa cum laude in 2010. He is now working towards his habilitation in the field of precise point positioning. He visited the Mathematical Geodesy and Positioning group at TU Delft as a guest researcher in 2007, and the GPS Lab at Stanford University in 2008 and 2010.
He received the Pierre Contensou Gold Medal at the International Astronautical Congress in 2007, the Bavarian regional prize at the European Satellite Navigation Competition in 2010, and the Vodafone Förderpreis for his dissertation in 2011.
