Septentrio Announces the AsteRx4 Next Generation Dual Antenna GNSS Receiver

Thanks to Septentrio’s positioning engine which uses advanced multipath and ionosphere modelling algorithms, the AsteRx4 offers robust positioning scalable from meter to centimetre accuracy. Together with precise heading and reliable error estimates, the AsteRx 4 OEM functions in the toughest conditions whether 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 the most obstructed areas such as in narrow city streets or at the corners of large structures. The AsteRx4 OEM features the full range of positioning techniques from stand-alone to 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 AsteRx 4 OEM is straightforward to set up and integrate with existing systems. 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”, says Jan Van Hees, VP of Business Development. “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 from April 14 at the National Oceanography Centre, Southampton, UK.
