Longitude, latitude and altitude from GPS In signal GPGGA The data of . So extracting these three information is mainly for GPGGA The data in the .GPGGA The data format of is as follows ：

clc;
clear;
close all;
warning off;


DATA_TYPE = 'GPGGA';% Select the type of data you want to keep 
fidin     = fopen('data.txt','r');
% Reading data 
tline = func_GPS_read(fidin);

% In the data GPGGA Save part of the data , The rest of the data is removed , In practice, , You can also change the following parameters , Select other data 
Save_data = func_save_usefull_data(tline,DATA_TYPE);


% Extract dimension 
% data fetch 
Dimensions = func_read_Dimensions(Save_data);
% Remove... From the data 0 value 
Dimensions(find(Dimensions == 0)) = [];
% Kalman filtering 
Dimensions_kalman = func_kalman(Dimensions);

figure;
subplot(211);plot(Dimensions);title(' dimension ');
subplot(212);plot(Dimensions_kalman);title(' dimension kalman');
xlabel('times');
ylabel('Dimensions');
% Extract longitude 
% data fetch 
longitude = func_read_longitude(Save_data);
% Remove... From the data 0 value 
longitude(find(longitude == 0)) = [];
% Kalman filtering 
longitude_kalman = func_kalman(longitude);

figure;
subplot(211);plot(longitude);title(' longitude ');
subplot(212);plot(longitude_kalman);title(' longitude kalman');
xlabel('times');
ylabel('longitude');



% Extraction height 
% data fetch 
Height = func_read_Height(Save_data);
Height(find(Height == 0)) = [];
% Kalman filtering 
Height_kalman = func_kalman(Height);


figure;
subplot(211);plot(Height);title(' Height ');
subplot(212);plot(Height_kalman);title(' Height kalman');
xlabel('times');
ylabel('Height');
