I tried today the binary mode on the mediatek module. The Longitude error, which was discussed earlier is still there, but i will update the firmware tomorrow, when i have access to a windows computer.
When switching to Binary mode with the
Serial1.print("$PGCMD,16,0,0,0,0,0*6A\r\n");
the module goes into binary mode, but the output frequency is still 1Hz.
How can the update rate be switched to 10Hz?
The NMEA switching commands commands are only made to switch the frequency of the NMEA sentences.
Is there any way to switch it or is this automatically done with the new firmware ?

$PMTK220,100*2F //Will set the GPS to 10hz (or updates every 100 milliseconds)
$PMTK220,250*29 //Will set the GPS to 4hz (or updates every 250 milliseconds)
$PMTK220,1000*1F //Will set the GPS to 1hz (updates every 1000 milliseconds)
You can set the GPS to any desired refresh rate, you change the value inside the string and generate a new check sum here: http://www.hhhh.org/wiml/proj/nmeaxor.html
