Control and communication
The NINA-W106 multiradio module runs the high precision GNSS application and controls the
communications between the ZED-F9R GNSS module and NEO-D9S L-band receiver module over the
I2C bus. NINA-W106 also connects to the LARA-R6 LTE Cat 1 modem through a 4-pin UART interface,

Correction data
XPLR-HPG-2 can receive GNSS correction data over Wi-Fi, through the GNSS and L-band antenna, or
either of the LTE antennas (1 and 2). The NINA-W106 module provides the Wi-Fi interface and
manages the decryption keys and receipt of GNSS correction data and between the three modules. In
this case, the XPLR-HPG-2 can work in three different modes of operation
–
described in the following
sub-sections as use cases:
•
Use case #1:
Correction data through L-band receiver
•
Use case #2:
Correction data through LTE Cat 1 modem
•
Use case #3:
