Text $GPGLL 621.33559 S 10639.666 E 20401 A*37

The data listed in column 2 indicates the value of south coordinate : 0621.33559

The data listed in column 4 indicates the value of east coordinate : 10639.666

The data listed in column 6 indicates the data of altitude : 20401

Performance Evaluation

Based on our experiment, the data from clientcan be sent to server every 1 second and the

server can received the data successfully without

delay as long as there is no problem in internetconnection. Therefore the track of the train can

be plot smoothly on the map and position of the

train can be monitored continuously.

Conclusion

The client software for tracking position of train using GPS hasbeen built using C++ Builder programming language.

The position data containing south, north, and altitude which

are sent by GPS successfully captured and selected by using

comma character as the key to parse data utilizing strtok()

function of C++.

The information send by client software can be received by

server and plotted on the map.
