Abstract

 

This document describes the XPLR-HPG-2 explorer kit used for evaluating and prototyping of high-
precision GNSS solutions. Describing the positioning, cellular and short-range radio modules hosted 
on the C214 host application board, this document explains the various module configurations and 
related use cases that can be explored using the kit. It also provides a quick start guide to get XLPR-
HPG-2 up and running as quickly as possible.
