Septentrio has launched two successors to the highly successfully APS-U. The AsteRx-U and the AsteRx-U Marine are multi-constellation dual antenna receivers which incorporate the latest GNSS tracking and positioning algorithms and interference mitigation.
“We want to make it easy for our customers to use high accuracy positioning in their work,” says Jan Leyssens, Septentrio product manager. “Using the integrated communication functionality in the compact and portable AsteRx-U, users won’t have to worry about adding their own modems or UHF radios to get access to corrections.”
Machine control users in the agricultural and construction industries, as well as users in marine and mining industries benefit from a complete system with integrated UHF radio, Wi-Fi, USB, Bluetooth and cellular connectivity and a spectrum analyzer. All configurations can be done via the on-board web interface.
The AsteRx-U and AsteRx-U Marine feature a full range of positioning techniques and algorithms to ensure high accuracy and reliability. The spectrum analyzer enables users to visualize the RF spectrum. Based on its extensive experience with real-life interference sources and their mitigation, Septentrio has developed interference mitigation technology that counteracts various kinds of ambient intentional and unintentional RF interference automatically.
The AsteRx-U family of receivers is built around Septentrio’s latest ASIC, GReCo4, which was introduced in 2014. It incorporates built-in jamming detection and countermeasures, multi-path rejection, fast acquisition, and other advanced features. Both receivers have more than 500 hardware channels to track all available constellations (GPS, GLONASS, Galileo, Beidou, IRNSS and QZSS) and feature many algorithms: LOCK+ technology to maintain tracking during heavy vibration machine use and IONO+ technology to assure the accuracy of the position even in regions of elevated ionospheric activity.
The AsteRx-U has decimeter and centimeter level RTK positioning including TerraStar, the AsteRx-U Marine supports additionally VERIPOS PPP augmentation services. It includes extra anti-jamming technology to counter Iridium and INMARSAT-uplink interference, as well as an extra antenna connector for a dedicated L-band antenna to optimize L-band reception at high latitudes.
Straightforward to setup and integrate with existing systems, the AsteRx-U and AsteRx-U Marine uses any device with a web browser to facilitate usability and configuration for the user.
The AsteRx-U will be presented to the public for the first time at ION GNSS+, taking place in Tampa, Fla., and InterGEO 2015, in Stuttgart, Germany.
Septentrio designs, manufactures and sells high-precision multi frequency multi constellation GPS/GNSS equipment used in in a variety of industries including marine, construction, agriculture, survey and mapping, GIS, UAVs and other industries. Septentrio is headquartered in Leuven, Belgium.
