GNSS OEM Boards - BX305 (1) 640x340px.jpg
The BX305 is a compact GNSS RTK receiver which offers real-time, centimeter-level positioning capability as well as flexible interfaces for a number of applications, such as precision navigation, precision agriculture, surveying, and UAVs. The BX305 can be integrated into other host devices or can serve as an independent positioning system that is dedicated to delivering high-precision, reliable position information.

About the 433/915 MHz RadiosThe radio is available in 915 MHz (US) and 433 MHz (Europe). The two radio transmitters/receivers in a RTK system need to be able to pass RTCM data from the base station to the rover receiver. The bundle includes a basic low-power radio link that is designed for short baseline applications. It has a transmit power of up to 100mW, which can support communications over approximately one kilometer range.
