Unicore Communications: Agriculture GNSS & GPS RTK

Machine control, digital site design, and high-precision positioning are becoming increasingly essential across road construction, earthmoving, mining, and grading applications. By combining Unicore GNSS modules with TruePoint correction services, we provide construction equipment OEMs and system integrators with an integrated technology foundation for incorporating centimeter-level positioning into excavation, grading, fine grading, paving, compaction, and automated operations.

Centimeter-Level, Dual-Antenna RTK Positioning
The UM982 and UM982C support multi-constellation, multi-frequency GNSS and dual-antenna RTK positioning. Each antenna can provide an independent RTK position, enabling centimeter-level positioning for critical points such as bucket tooth tips, blade height, and grading points.
Flexible Correction Options
The solution supports multiple correction data sources and delivery methods, including RTCM-based corrections, CORS/VRS networks, TruePoint correction services, and satellite-based L-band delivery. Select ground-based augmentation or satellite-based PPP to suit the deployment area and cost requirements.
Evaluation Kits and Reference Designs
Unicore provides GNSS modules, evaluation kits (EVKs), antennas, and access to correction services to support system evaluation and integration. These resources help streamline development, accelerate prototyping, and shorten time to market.

High-Precision Machine Control Solutions for Construction Equipment

RTK positioning accuracy: 0.8 cm + 1 ppm (RMS) horizontally and 1.5 cm + 1 ppm (RMS) vertically. This level of accuracy supports precise positioning of machine components and control of parameters such as bucket tooth tip position, blade height, and paving thickness.

Multi-constellation GNSS: Supports GPS, Galileo, BeiDou (BDS), GLONASS, and QZSS, improving satellite availability and helping maintain RTK fixed solutions in challenging
environments with partially obstructed sky visibility, such as fencing, slopes, or structures. Positioning update rate: Up to 20 Hz.
Correction input: RTCM 3.x, CORS/VRS, and TruePoint correction services via IP or L-band.
Output protocols: Unicore proprietary protocols, NMEA, and RTCM for integration with machine controllers and fleet-management systems.
Interfaces: UART, SPI*, and I2C* (*SPI and I2C functionality requires specific firmware support).
Operating temperature: -40 °C to +85 °C, industrial grade

Effective machine control relies on accurate positioning, reliable attitude information, and appropriate correction data as key inputs to the control system.

Unicore offers a broad portfolio of positioning technologies to address diverse accuracy, coverage, and deployment requirements. These include multi-constellation, multi-frequency on-chip RTK, dualantenna heading, interference and spoofing detection, and a range of satellite-based augmentation and precise positioning services, including BDS B2b PPP, Galileo E6 HAS, QZSS L6E (MADOCA) PPP, PPP Via SouthPAN L5, TruePoint | REACH satellite-based L-band PPP-AR, and QZSS L6D (CLAS) PPP-RTK.
These technologies provide flexible implementation options from initial system development to scalable, high-volume production.
