我在学习GPS编程时写的DELPHI源码 ,比较简单.希望大虾不要见笑.多多指教.
procedure TfrmMain.DrawSatInfo(gps: TGPSInfo; pbx: TPaintBox);
var
i: integer;
r: integer;
dx,dy: integer;
begin
r := pbx.Width div 2;
for i:= 1 to 12 do begin
if gps.SatInfo[i].PRN 0 then begin
dx := r + Round(r*(90-gps.SatInfo[i].EL)*sin((gps.SatInfo[i].AZ - 90)*Pi/180)/90);
dy := r + Round(r*(90-gps.SatInfo[i].EL)*cos((gps.SatInfo[i].AZ - 90)*Pi/180)/90);
dx := dx - 8;
if dx < 0 then dx := 0;
if gps.SatInfo[i].SN > 20 then begin
pbx.Canvas.Font.Color := clBlue;
pbx.Canvas.TextOut(dx,dy,inttostr(gps.SatInfo[i].PRN));
end else begin

INS_Kalman卡尔曼滤波程序 GPS INS 组合导航例子
基带测量信号处理的算法:1.最小二乘曲线拟合法2.线性滤波方法3.非线性滤波方法非线性滤波方法就是和深组合导航系统中利用联邦卡尔曼滤波的方法是一样的,基带信号处理相当于联邦卡尔曼滤波中的局部滤波器
