- GPS Altitude: Now you can read the altitude function in the dGPS sensor. This function is not as accurate as horizontal measurements, but with enough satellites in view, it can provide a relatively accurate altitude. Your NXT is now an altimeter.
- Satellites In View: Ever wondered if where you’re standing is causing an inaccuracy in your GPS reading? Now you can get a better fix on how many satellites are in view and how accurate your reading is.
- HDOP: (Horizontal Dilution of Precision.) This function gives a reading of just how accurate your reading is.
We’ve also added another bell/whistle: a blinking LED. When you power up your dGPS, the blue LED (signal-acquired LED) blinks 3 times, letting you know the firmware is properly installed and the sensor has started up.
We have been shipping dGPS GPS Sensor for Lego MINDSTORMS NXT with this new firmware since July.
