The AsteRx-m3 ProBase from Septentrio is a Multi-Frequency, Multi-Constellation GNSS Receiver designed to operate as a reference station for local RTK or network densification. It features the latest Septentrio quad constellation GNSS technology for high-quality measurements and generates real-time differential and RTK corrections which can be used in GNSS and GNSS/INS products to achieve centimeter-level accuracy. This module has a cold start time of less than 45 s, a warm start of less than 20 s, and an average re-acquisition time of 1s. It requires a DC supply from 3.3 to 5 V and consumes 1 W of power. The receiver has an antenna gain range from 15 to 45 dB, provides a tracking sensitivity of 20 dB-Hz, and acquisition sensitivity of 33 dB-Hz. It has a latency of less than 10 ms and supports UART, Ethernet, USB, GPIO, TCP/IP, and UDP interfaces.
The AsteRx-m3 ProBase features AIM+, an advanced onboard antijamming technology that can suppress the widest variety of interferers, from simple continuous narrowband signals to the most complex wideband and pulsed jammers. The RF spectrum can be viewed in real-time in both time and frequency domains. Septentrio’s industry-leading APME+ technology aids in achieving the best multipath rejection while IONO+ ensures the best measurements and accuracy even under intense ionospheric activity.
The AsteRx-m3 ProBase supports multiple standard correction messages for best compatibility when integrating GNSS technology. This multi-signal receiver generates the highest quality corrections ensuring reliable positioning accuracy for end users. It is easy to integrate and comes with fully documented interfaces, commands, and data messages. Raw data logging can easily be set-up with this OEM board and the included RxTools software allows receiver configuration, monitoring, and data analysis. An SDK is provided to help integrators create professional custom applications.
This GNSS Receiver is available in a compact surface-mount package that measures 47.5 x 70 x 9.32 mm with 2 MMCX antenna connectors and is ideal for use in reference network stations, survey & GIS, and scientific applications.
