Still worried about the power....
For 1~4Hz GPS NMEA data string, 1200~4800 baudrate is enough.
My GPS uses 5V power with 48mA working current.
If I attach the GPS directly onto the AR.Drone's serial port, it is powered from the USB +5V VBUS Pin (with dwc_otg.ko loaded).
If I attach the GPS onto Arduino Nano, it is powered from the Nano's +5V Pin.
