Septentrio has launched its next-generation dual-antenna GNSS receiver, the AsteRx 4 OEM. The AsteRx 4 OEM is a multi-frequency, dual antenna receiver that incorporates the latest innovative GNSS tracking and positioning algorithms from Septentrio. It offers users in the marine, machine control and agricultural industries precision, accuracy, reliability and ease of use, the company said.

Thanks to Septentrio’s positioning engine, which uses advanced multipath and ionosphere modeling algorithms, the AsteRx4 offers robust positioning scalable from meter to centimeter accuracy. Together with precise heading and reliable error estimates, the AsteRx 4 OEM functions in tough conditions on land, at sea or in the air.  

Use of all available constellations (GPS, GLONASS, BeiDou, Galileo) provide the operator with a reliable solution even in obstructed areas such as in narrow city streets or at the corners of large structures, Septentrio said. The AsteRx4 OEM features the full range of positioning techniques from stand-alone to real-time kinematic (RTK).

For users who operate in more remote regions of the globe, the AsteRx4 OEM supports Veripos and Terrastar correction PPP services. Furthermore, the receiver features special interference mitigation technology which filters out ambient intentional and unintentional RF interference.

The AsteRx4 OEM is straightforward to set up and integrate with existing systems, Septentrio said. It has the similar hardware interface as earlier AsteRx receivers, and supports the same open and well documented command and binary output format. Users will be able to operate their receiver without special configuration software by using the very accessible web interface, which is available via network and USB connections.

“AsteRx4 incorporates many powerful improvements based on practical difficulties our customers face in the field every day,” said Jan Van Hees, vice president of Business Development, Septentrio. “We are particularly proud of the solutions for interference robustness that we have incorporated into our new ASIC,  the GReCo4; the solid and reliable positioning algorithms that result from taking the receivers into the most extreme environments and from focusing not only on accuracy, but on reliability of the position solution.”

The AsteRx4, along with all the AsteRx family of receivers, will be on display at booth W40 for the duration of Ocean Business 2015 starting April 14 at the National Oceanography Centre, Southampton, UK.
