基于平均值预测数据

我每秒钟都有GPS数据进入我PC上的串行端口。我已经成功地处理了GPS数据，纬度和经度以浮点数的形式存储在单独的数组中。

double[] dlat = new double[100000]; //contains the latitude data
double[] dlon = new double[100000]; //contains the longitude data

大多数情况下，经纬度数字保持不变，因为GPS位置每5米才变化一次。当数组中的纬度或经度值发生变化时，我希望程序根据变化之间存储的数据点的平均值来预测纬度或经度。例如:

假设这是latitude数组的内容:

2,2,2,2,2,17

我希望我的程序将数组中的内容更改为:

2,5,8,11,14,17   

我已经尝试解决这个问题，但我的方法不起作用:-/我是c#的新手;一定有更好的办法。下面是我的代码片段，它试图做预测(---GPS coordinate prediction---之后的位是不工作的位):

string RxString;// where the raw serial data is stored
string mag;
double[] dmag = new double[100000];//magnetic data stored here
string lat;
double[] dlat = new double[100000];//latitude data stored here
string lon; 
double[] dlon = new double[100000];//longitude data stored here
double average;//average step between change in latiude
int i; //pointer double array data;
int count;//counter for prediction code
private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)//activates when port is open and data in buffer
{
    RxString = serialPort1.ReadTo("'r'n");//read raw data from serial port into string
    this.Invoke(new EventHandler(DisplayText));//invoke allows it to call function diplay text*/
    if(RxString.StartsWith("G"))
    {
       lat = RxString.Split(',')[0].Substring(4);// extract latitude
       this.Invoke(new EventHandler(DisplayText1));//invoke allows it to call function diplay text
       dlat[i] = Convert.ToDouble(lat);//convert and store in double array
       this.Invoke(new EventHandler(Form1_Load));//invoke allows it to call function 
       lon = RxString.Split(',')[2];// extract longitude
       this.Invoke(new EventHandler(DisplayText2));//invoke allows it to call function diplay text
       dlon[i] = Convert.ToDouble(lon);//covert and store in double array
       this.Invoke(new EventHandler(Form1_Load));//invoke allows it to call function 
       mag = RxString.Split(',')[3].Substring(6).Trim();// extract magnetic data 
       this.Invoke(new EventHandler(DisplayText3));//invoke allows it to call function diplay text
       dmag[i] = Convert.ToDouble(mag);//convert and store in double array
       this.Invoke(new EventHandler(Form1_Load));//invoke allows it to call function 
       i++;
       RxString = null;
        /* -------------------------GPS coordinate prediction--------------------------------------------- */
       if (i > 0)
       {
           if (dlat[i] == dlat[i - 1])
           {
               count++;
           }
           if (dlat[i] != dlat[i - 1])
           {
               double average = (dlat[i] - dlat[i - 1]) / (count);//average data step beween changed values
               int firstAv = i - (count - 1);//position of first average
               int lastAv = i - 1;//position of last average
               for (int j = firstAv; j <= lastAv; i++)
               {
                   dlat[j] = dlat[j - 1] + average;
               }
               count = 0;
           }
       }
       if (i==0) count = 1;
   }
