以下是一个基于C#实现的BDS NMEA-0183数据解析上位机的示例代码，包含基础功能和界面：

using System;
using System.Collections.Generic;
using System.IO.Ports;
using System.Windows.Forms;
using System.Drawing;
using System.Globalization;

namespace BDS_NMEA_Viewer
{
    public partial class MainForm : Form
    {
        private SerialPort serialPort;
        private Dictionary<int, Satellite> satellites = new Dictionary<int, Satellite>();
        
        public MainForm()
        {
            InitializeComponent();
            InitializeControls();
        }

        private void InitializeControls()
        {
            // 串口配置
            cmbPort.DataSource = SerialPort.GetPortNames();
            cmbBaudrate.Items.AddRange(new object[] { 4800,
