GPS/GNSS receiver offers always-on sub-decimeter accuracy

Septentrio has launched the AsteRx-m2 Sx OEM GNSS receiver offers a sub-decimeter positioning solution with no need for a subscription correction service.

The new solution provides high-accuracy positioning directly out of the box with GNSS corrections automatically streamed to the receiver. This eases the GNSS receiver set-up process and gets rid of corrections service subscription and maintenance.

The AsteRx-m2 Sx OEM GNSS receiver can receive information from all available Global Navigation Satellite Systems, including the American GPS, European Galileo, Russian GLONASS, Chinese BeiDou, Japan’s QZSS and India’s NavIC. These satellite constellations broadcast positioning information to receivers which use it to calculate their absolute position.

Danilo Sabbatini, Product Manager at Septentrio said, “By integrating the correction service directly into the GNSS receiver we are removing the hassle of positioning service set-up and maintenance from the user. This means faster set-up times for our customers and worry-free, always-on high accuracy positioning throughout the receiver lifetime.”

AsteRx-m2 Sx has been developed as an efficient positioning solution for small robots, aerial drones and automation applications. It is designed to optimize size, weight and power (SwaP) to allow longer operation on a single battery charge, as well as better value in the field. The device also features advanced anti-jamming technology, AIM+, to ensure robust and reliable operation in challenging environments even in the presence of RF interference, which is often caused by illegal devices called “jammers”.

AsteRx-m2 Sx offers lifelong (typically five years) sub-decimeter accuracy with fast convergence time in US and Europe.
Septentrio will also host a free, live webinar on “GNSS Corrections Demystified” on 8th July 2020 5PM CEST or 8 PM PST time. Registration is at
