    Unicore has released its new generation of GNSS positioning product, the UM982. The UM982 is a high-precision dual-antenna real-time kinematic (RTK) positioning and heading module supporting all constellations and all frequencies.

    The UM982 is suitable for use in UAV, precision agriculture and autonomous machine applications. The module is designed to meet the requirements of  these markets, providing technological innovation. The module supports BDS B1I/B2I/B3I, GPS L1/L2/L5, GLONASS L1/L2, Galileo E1/E5a/E5b, QZSS L1/L2/L5 and SBAS in dual-antenna mode. It offers the following advantages.

    Small size. The UM982 is highly integrated. With its size of 16.0 × 21.0 × 2.6 mm, it is a compact dual-antenna heading modules that reduces the design area of the customer’s board by 72% compared to previous modules.

    Low power consumption. Low power consumption means less energy usage and a better application experience. Lowering the power consumption while keeping performance high is one of the key technical research directions of the GNSS positioning modules. The average power consumption of all versions of the UM982 module is less than 0.6 W, which is suitable for applications that require low power consumption, such as UAVs.

    High integration. The UM982 was developed on the basis of NebulasIV, Unicore’s proprietary GNSS system on chip (SoC). NebulasIV integrates RF, baseband and high-precision algorithms on a single chip, with built-in functions providing powerful support for the UM982’s high performance.

    High precision and high performance. The GNSS SoC is a key part of the navigation system, and the performance of the chip largely determines the performance of positioning modules. High-level performance indicators include raw observation accuracy, RTK positioning accuracy, PPP positioning accuracy, and time to first fix.

    Robustness. Using the company’s dual-RTK technology, the UM982’s two antennas can independently participate in deriving an RTK solution and outputting the positioning results. This is convenient for customers conducting reliable verification in various application scenarios. By checking the RTK positioning results of both antennas, abnormal measurements in complex scenarios can be avoided.

    High reliability. A built-in, advanced anti-jamming unit provides the UM982 with strong anti-jamming ability. The module detects jamming and can output the jamming strength. It also supports digital encryption to ensure the security of data transmission, and supports multi-frequency independent acquisition and tracking to ensure the reliability and accuracy of positioning results even in complex electromagnetic environments.

    Although GNSS has been applied in agriculture for many years, farmers still encounter challenges caused by GNSS. No matter the farm task — planting, spraying, harvesting or specialized applications such as robotic grass mowing — position accuracy matters.
    Here are the most common issues farmers have and how Unicore’s products help.

    • Under canopy. They are unable to get a fix under heavy foliage canopy because the real-time correction signal is interrupted or “shaded out” by the canopy. Unicore is launching two new modules that will help mitigate this problem.
    • Loss of lock. At times, the receivers lose lock or get large position errors when the ionosphere’s effects are severe. Driven by a full-constellation and full-frequency RTK engine, Unicore’s RTK algorithm takes advantage of triple and quad frequency observables, effectively mitigating ionospheric residuals.
    • Loss of 4G signals. RTK can provide real-time centimeter-level high-precision positioning, which requires real-time base station data. In practical applications, radio or wireless network communication is often interrupted. During the interruption of the base station data, RTK’s positioning accuracy decreases quickly. Unicore’s RTK KEEP technology can maintain the centimeter-level positioning accuracy for more than 10 minutes after the interruption.
    • Lack of CORS stations. It is challenging to provide a stable high accuracy position for an ultra-long baseline. With the mitigation of ionospheric and tropospheric delays, Unicore products’ RTK baseline can be extended to up to 50 kilometers.

    The UM980 is Unicore’s new-generation high-precision RTK positioning module, supporting full constellation and full-frequency. Relying on the strengths of high reliability, precise positioning accuracy and low latency, UM980 is not only well suited for high-precision surveying and mapping, but also a good choice for rover or base station receivers in agriculture.

    The UM982 is a dual-antenna high-precision positioning and heading module. Since its master and slave antennas can simultaneously track all the frequencies of all the GNSS systems, the UM982 performs fast on-chip RTK positioning and dual-antenna heading solutions without the need to initialize the IMU. Featuring great positioning performance and stability, the UM982 is a perfect choice for high-precision agriculture applications, such as drones, autonomous tractors and autonomous lawnmowers.

    Both products will be available in June 2022.
