The future availability of different GNSS satellite constellations is leading to the need for navigation receivers capable of jointly managing GPS, SBAS and GALILEO signals and flexible enough to accommodate both future signal evolutions and easy integration with other technologies, such as communication and inertial sensors. This open-platform GNSS navigation receiver architecture, based on SDR and next-generation hardware and software, allows such flexibility and reconfigurability. The end-user client software can run on devices based on defined APIs. The GNSS application supports integration of users’ geospatial content databases and user-defined algorithms that enhance device performance or usability for a specific application. The user can access and process three levels of data, including basic I/Q digitised samples, raw measurements, and full navigation and integrity output. The open platform is a miniaturised, reconfigurable, single-board dual-frequency receiver that offers pre-installed core-navigation software libraries covering typical user accuracy and integrity requirements for a wide range of safety-of-life and professional navigation, positioning and timing applications.
Solutions available on the market are typically closed, black-box products that process predefined signals and frequency bands. The proposed architecture is reconfigurable to virtually any GNSS signal and frequency band and able to host user-defined algorithms and software to carry out a specific application, reducing the need for additional external hardware or software resources. The platform is targeted toward high-end professional and safety- of-life applications. It facilitates access to the different levels of data generated by the receiver.
The solution’s target market involves safety-of-life applications in rail, air, and sea transport, as well as professional regulated applications ranging from geodetics to railway monitoring and surveying, train supervision & diagnostic applications, infrastructures monitoring, emergency service applications.
Users can easily access GNSS data at different levels, as well as customise and configure the device for specific applications. The solution provides a robust, reliable and accurate GNSS sensor device also usable in regulated services or systems requiring certification. The GNSS sensor is capable of processing all GPS/ SBAS/Galileo signals.
