2 AsteRx-U3 overview
The AsteRx-U3 provides multi-frequency, multi-constellation GNSS positioning capability
together with GNSS Heading and wireless communication options within a rugged IP68
housing for the broadest range of applications. AsteRx-U3 can be easily monitored and
configured without any special software via the built-in web user interface accessible via
WiFi, Ethernet or USB connection.
