Support INS+GNSS navigation
Surface-mounted design and small size to integrate
High-performance floating-point arithmetic
Industry-leading low power consumption
Internal adaptive anti-interference algorithm
With up to 20Hz IMU data update rate and inertial navigation fusion
algorithm, K803 can provide continuous and high-quality positioning
data in the harsh environments such as tunnels, buildings and forests.
The K803 has internal adaptive anti-interference algorithm which
enables the module effectively suppress wideband, narrowband and
continuous-wave interference. It can provide users with high-quality
observing data even in the complex electromagnetic environment.
The K803 incorporates ComNav’s new generation high-accuracy
Quantum III SoC chip with the capability of tracking all the GNSS
constellations and signals. It can provide users with highly reliable
positioning information with support of high-performance floating
point arithmetic.
