GPS Data Logger Software - BT747

Hello Friends,

I implement GPS logger facilty in my own application using BT-Q1000x device.

I am trying to read row data  from device.Application using dot net code -

                string data = serialPort1.ReadExisting();
                string[] strArr = data.Split('$');
                for (int i = 0; i < strArr.Length; i++)
                {
                    string strTemp = strArr[i];
                    string[] lineArr = strTemp.Split(',');
                    if (lineArr[0] == "GPGGA")

I got row data like this -

$GPGGA,100339.271,,,,,0,0,,,M,,M,,*44
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGSV,1,1,00*79
$GPRMC,101659.271,V,,,,,0.00,0.00,221209,,,N*49

$GPGGA,101700.271,,,,,0,0,,,M,,M,,*4B
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGSV,1,1,00*79
$GPRMC,101700.271,V,,,,,0.00,0.00,221209,,,N*44

$GPGGA,101701.271,,,,,0,0,,,M,,M,,*4A
$GPGSA,A,1,,,,,,,,,,,,,,,*1E
$GPGSV,1,1,00*79
$GPRMC,101701.271,V,,,,,0.00,0.00,221209,,,N*45 etc.

etc.

Is this right data?
