Product overview

The Sinan Navigation QC7820 is a fourth-generation high-precision GNSS SoC for applications including UAVs, intelligent driving, robotics, IoT, intelligent monitoring and smart agriculture. It supports RTK, RTD, PPP, PDP, SPP and combined GNSS/IMU positioning, with single-antenna positioning and dual-antenna heading determination. Its all-system, all-frequency architecture supports BDS, GPS, GLONASS, Galileo, IRNSS, QZSS and SBAS, together with L-band, satellite-based augmentation and low-Earth-orbit satellites. Multi-system positioning and heading, ground-based and satellite-based augmentation, and integrity technology support the delivery of position and attitude information.

Built on a 22nm process, the 7mm-square chip integrates GNSS baseband, RF, power, processor, memory and interface circuitry, eliminating the need for an additional RF chip. Its dual-core processor operates at 800MHz, with a maximum of 1.2GHz, and supports high-performance floating-point operations. The QC7820 provides 1688 channels and a configurable data update rate of up to 100Hz. Typical power consumption is 250mW, falling to 150mW in low-power mode. Wideband RF input, narrowband interference suppression and an ultra-low-power continuous-wave cancellation module support operation in harsh environments.
