 This is a GPS receiver with antenna array, built based on USRP X310 and GNSS-SDR.
+
+## Introduction
+This project is a GPS receiver with antenna array, built based on USRP X310 and GNSS-SDR. The receiver is designed to receive GPS signals from multiple antennas and process them to improve the accuracy of the position estimation. The receiver is built using GNSS-SDR, an open-source software defined radio receiver for GNSS signals.
+
+## Hardware
+The hardware used in this project includes:
+- USRP X310: a software-defined radio platform for receiving and transmitting radio signals.
+- GPS antennas: multiple antennas are used to receive GPS signals from different directions.
+- GPS receiver: a GPS receiver module for receiving GPS signals.
+- Antenna array: an antenna array is used to receive GPS signals from multiple antennas and process them to improve the accuracy of the position estimation.
+
+## Software
+The software used in this project includes:
+- GNSS-SDR: an open-source software defined radio receiver for GNSS signals.
+- USRP driver: a driver for USRP X310 to communicate with the USRP hardware.
+- GPS receiver driver: a driver for GPS receiver module to communicate with the GPS receiver hardware.
+
+## Usage
+To use this project, you need to install GNSS-SDR, USRP driver, and GPS receiver driver. Then, you can configure the GNSS-SDR to use the USRP X310 and GPS receiver module to receive GPS signals from multiple antennas and process them to improve the accuracy of the position estimation. The configuration file for GNSS-SDR can be modified to adjust the parameters of the receiver, such as the sampling rate, the number of antennas, and the position of the antennas.
