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: •... -
Page 10: Use Case #1: Correction Data Through L-Band Receiver
2.3.1 Use case #1: Correction data through L-band receiver L-band represents the range of frequencies in the radio spectrum from 1 2 GHz to 2 GHz, which is the top end of the ultra-high frequency (UHF) band and the lower end of the microwave range. In this use case #1, the NEO-D9S module receives correction data through LBAND and the NINA- W106 module gets the correction data from NEO-D9S through the I2C bus. -
Page 11: Use Case #2: Correction Data Through Lte Cat 1 Modem
2.3.2 Use case #2: Correction data through LTE Cat 1 modem In this scenario, the correction data flow stars when the LTE Cat 1 modem (LARA-R6) receives the correction data and the decryption keys through the cellular network using an MQTT connection to the cloud based Thingstream delivery platform for IoT services. -
Page 12: Use Case #3: Correction Data Through Wi-Fi Connection
2.3.3 Use case #3: Correction data through Wi-Fi connection In this scenario, the NINA-W106 functions as a Wi-Fi host and receives the correction data and the decryption keys through a Wi-Fi network using an MQTT connection. This data is then forwarded to the GNSS module (ZED-F9R) over the I2C bus. -
Page 13: Power Subsystem
In situations where the USB-C connector provides excessive power, the power path management functionality offered by the latter battery charger option adjusts power to the XPLR-HPG-2 board and charges the battery simultaneously. Conversely, the battery compensates for the power deficiency if the USB-C connector provides insufficient power. -
Page 14: Software
Software HPG software operates autonomously, configures all the modules, handles the different correction data sources, and provides the correction data to the GNSS module. This is possible with the HPG library [18] built on top of ubxlib for high-precision GNSS tailored projects. Figure 9 shows the HPG data topology for each of the HPG use case... -
Page 15: U-Blox Library (Ubxlib)
3.2 u-blox library (ubxlib) HPG software makes use of open-source u-blox library (ubxlib), which provides C libraries for connecting the various u-blox modules and building embedded applications easily. The goal of ubxlib is to deliver a single tested solution, with examples, which provides uniform easy-to-use APIs across several u-blox products. -
