Reading GPS data  - SOLVED

Hi everyone.
I'm trying to use GPS data coming from PMB-248 GPS Receiver in order to calculate distance to my target. When I use Serial.print(GPS.read(),BYTE); I see all NMEA data. I use char array to store specific parts of the NMEA data, however if I print this char array the displayed data misses every second symbol. I'm using the following code

#include <SoftwareSerial.h>

SoftwareSerial GPS(2,300); // rx pin = 2 for GPS
char tag[6], gpsData[60]; 

void setup()
{
  GPS.begin(4800);
  Serial.begin(9600);
}

void GPSRead()
{
  while(1)
  {
    if(GPS.read() == '

The data should come out like this:
183356,4239.4169,N,02321.3495,E,0,00,,00655.8,M,036.9,M,,
but the char array stores only this:
140,2946,,22.45E00,0658M069M,

I'm not sure what I'm missing here...
I'll appreciate your help.

Best regards,

   {
     for(int i=0;i<6;i++)
     {
       tag[i] = GPS.read();  
     }
     if(memcmp(tag, "GPGGA,",6) == 0)
     {
       GPSCollect();
       break;
     }
   }
 }
 Serial.println(gpsData);
}

void GPSCollect()
{
 for(int i=0;i<60;i++)
 {
   gpsData[i] = GPS.read();
   if(GPS.read()=='*')
   {
     break;
   }
 }
}

void loop()
{
 GPSRead();
}

    gpsData[i] = GPS.read();
    if([glow]GPS.read()=='*'[/glow])

You're reading, but not storing in the highlighted section.

Did you mean:

    gpsData[i] = GPS.read();
    if(gpsData[i] =='*')

?

AWOL, thank you so much. This change fixed the problem.
