Nebulas IV UC9810 is Unicore's new generation proprietary GNSS SoC that integrates RF, baseband, and high-precision algorithms.
By leveraging the 22nm process node architecture, a high-performance multi-mode baseband GNSS processor, and an embedded microprocessor, the chip delivers superb performance and maintains low power consumption. UC9810 supports 1408 channels and tracks multiple signals, including GPS L1C/A, L1C, L2C, L2P(Y), BDS B1I, B2I, B3I, B1C, B2a, B2b, L5, GLONASS G1, G2, G3, Galileo E1, E5a, E5b, E6, and QZSS L1, L2, L5, as well as the L-band. The integrated RTK matrix processing technology allows the chip to deliver enhanced all-system all-frequency centimeter-level RTK positioning and orientation. Due to its tight integration, high performance, low power consumption, and compact form factor, Nebulas IV is an ideal solution for technically demanding high-precision applications, such as drones, robotic lawn mowers, precision agriculture, surveying, mapping, intelligent driving, and timing. Nebulas IV supports a wealth of external interfaces that cover almost all common application interfaces, including DMA, timer, watchdog, battery, SDRAM, FLASH, CAN, network, UART, SPI, I2C, odometer, and freely configurable GPIOs.
