2 AsteRx-U overview
The AsteRx-U provides multi-frequency, multi-constellation GNSS positioning capability
together with GNSS Heading, L-Band positioning and wireless communications within a
rugged IP67 housing for the broadest range of applications. Use any smartphone, tablet or
computer to operate the AsteRx-U without any special configuration software via the built-in
webserver accessible via WiFi, Ethernet or USB connection.
2.1 AsteRx-U key features
