Septentrio AsteRx-m2 Sx GNSS Receiver Board

The AsteRx-m2 Sx from Septentrio is a compact, high performance, ultra-low power GNSS receiver board ideal for integration in UAS, handheld devices and other demanding industrial applications where power and space are at a premium. It delivers out-of-the-box sub-decimeter accuracy thanks to the built-in PPP-RTK correction service.

Overview

The AsteRx-m2 Sx GNSS receiver board from Septentrio provides high-accuracy GNSS positioning right out of the box. No need for any additional correction service selection, subscription and maintenance. This robust OEM receiver board delivers reliable sub-decimeter accuracy with short convergence time. This is made possible by an integration of a PPP-RTK high-accuracy correction service into Septentrio’s latest core GNSS technology.

The AsteRx-m2 Sx provides RTK positioning at the lowest power consumption of any comparable device on the market. Its minimal SWaP (Size, Weight and Power) means longer operation on a single battery charge and better value in the field.

The AsteRx-m2 Sx comes with fully-documented interfaces, commands and data messages. The included RxTools software allows receiver configuration and monitoring as well as data logging and analysis. An SDK is provided to help integrators create professional custom applications. The AsteRx-m2 Sx is compatible with GeoTagZ Software and its SDK library for PPK (Post-Processed Kinematic) offline processing.
