best meathod to capture serial data?

I appreiate the response.
I was just trying to debug it with this code.

case pF5sCollectTheData:  //header is 27 bytes, message 30 per sv no delimters 990bytes possible
      TimerA = millis();
      //  trial1
      Serial.println("entering F5 data collection state");
      while( messageF5 == false){
        for( n=0 ; n<800; n++){
          Serial2_WaitForByte(&tempArray[n]);
          if (tempArray[n] == 0x03 && tempArray[n-1] == 0x10){
            messageF5 = true;
            Serial.println("F5 complete in array");
          }
        }
      }
      if (messageF5 == true){
        n = 27;
        for(int b=0; b<8 ; b++){
          Serial.println(tempArray[n], DEC);
          Serial.println(tempArray[n+29], DEC);
          n = n + 30;
        }
        state = Fini;
      }
      break;

So I get an expected output for the first few satilites. Each segment has an unused byte that should always be 0 and each should start with a system ID 1,2, ect. So maybe I can search down the whole array finding the 1,2,ect and check to see if +29 bytes there is a 0. Based on that I should have very good odds that it would be a good segment.
