Try this...

Code:
awk '{
    k=substr($0, 11, 13)
    _xy=substr($0, 57, 18);
    split(_xy, aa)
    x[k]+=aa[1]; y[k]+=aa[2]; s[k]++
    if(k in key) next
    key[k]=$0
  }
  END{
    for(k in key){
      _xy=substr(key[k], 57, 18);
      sub(_xy, sprintf("%.1f", x[k]/s[k])" "sprintf("%.1f", y[k]/s[k]), key[k])
      print key[k]
      delete key[k]
    }
  } ' infile

The first line seen is printed after taking the average of the x,y of the subsequent records. The output will not be in the same order as the input.
If you feel, there is an issue with round off - implement the round off function from here https://www.gnu.org/software/gawk/ma...-Function.html
