Product overview
The Sinan Navigation K902 combines a proprietary QC7820 SoC with an integrated IMU in a high-precision GNSS positioning module. It receives signals across all supported satellite systems and frequencies, with support for BDS, GPS, GLONASS, Galileo, QZSS, SBAS and IRNSS. RTK, PPP and SPP positioning modes serve surveying and mapping, outdoor robotics and ground-based augmentation applications. The module also supports on-chip integrated navigation processing and can achieve centimeter-level positioning accuracy.
Built around a 22 nm main chip, the K902 incorporates a dual-core processor operating at up to 1.2 GHz with support for high-performance floating-point computation. Its compact, low-power surface-mount design facilitates integration. Interference suppression targets narrowband and multitone radio interference within the signal band, while onboard inertial navigation supports operation in obstructed environments. Intelligent driving is another application field for the module.
