The state-of-the-art 66 channels MediaTek MT3329 GPS Engine
High
sensitivity: Up to -165dBm tracking, superior urban performance
USB/UART
Interface
Build-in patch antenna for optimal sensitivity
DGPS(WAAS,
EGNOS, MSAS) support (optional by firmware)
Maximum update rate : up
to 10Hz (optional by firmware)
RoHS compliant
Note that the new MediaTek has custom and exclusive "DIYDrones" firmware
that allows the unit to output an efficient and very compressed binary
protocol (This firmware will only work with our modules!). You can still change between NMEA and Binary protocol with
standard MTK messages, and switch the refresh rate between 1hz to 10hz,
or set any standard serial baud rate (by default is set to 38400 bps and
custom binary protocol).
Arduino example for decoding the custom binary protocol is provided.
Remember to install the library folder "GPS_MTK" inside the Arduino IDE
"libraries" folder "\arduino-00XX\libraries\\". For the most updated code, please go to
this page. Once there, download the most recent "ArduPlane X.XX.zip" file; open the "libraries" folder and then "AP_GPS" where you'll find the most recent code.
