The receiver of
KL3333 is based on a modern specialized chipset of MT 3333, representing
the family of so-called "systems on a chip", manufactured by Mediatek of the world leader in the
production of chips for navigation and multimedia systems.
Receiver possesses high sensitivity; low power consumption and low start time.
The receiver has 99 channel for
acquisition (capture) and 33 channels to track the satellite
signals that allows simultaneous search of satellite signals groups of GLONASS and GPS.
The receiver lets you apply for a primary search of satellite signals specially prepared
information stored in the receiver's memory that reduces the time of cold start. Moreover, that it is
essential to make a cold start in a weak signal from satellites.
Specific information can be prepared
by external sources (and transferred to the receiver through the communication channels), and
independently by the receiver. In the latter case, it is not required to obtain any additional
information from external sources.
The receiver has a built-in noise suppression that allows it to operate in a difficult jamming
environment.
The operation of the receiver is carried out by means of special NMEA-like
commands.
The receiver is equipped with a serial port of the
UART.
To learn more about the operation of the receiver of KL3333 may meet the
"KL3333 demo
board".
KL3333 demo board is a complete analogue of
