STMicroelectronics Smart Agriculture Solutions
Precision agriculture increasingly relies on accurate positioning data to guide machinery, monitor field operations, and support automated farming workflows. Applications such as precision planting, autonomous tractors, drone-based field inspection, and variable-rate input application all depend on reliable location information to ensure that equipment operates efficiently and consistently across large agricultural environments.
STMicroelectronics supports these applications through its Teseo family of GNSS receivers and modules, which provide high-accuracy positioning capabilities for industrial and automotive applications. The latest generation, Teseo VI, introduces advanced multi-band and multi-constellation GNSS capabilities designed to improve positioning accuracy, signal availability, and resilience in challenging environments.
By combining high-performance GNSS receivers with integrated sensors and advanced signal processing, STMicroelectronics enables developers to build robust positioning systems capable of supporting the next generation of smart agricultural equipment.
Multi-constellation GNSS for agricultural systems
Modern GNSS receivers increasingly rely on signals from multiple satellite constellations to improve positioning performance. Instead of relying solely on GPS, advanced receivers can combine signals from Galileo, BeiDou, GLONASS, QZSS, and IRNSS, significantly increasing satellite availability and improving positioning reliability.
This multi-constellation approach is particularly valuable in agricultural environments where machinery may operate in conditions that affect signal reception, such as dense vegetation, uneven terrain, or partial obstruction of the sky view.
The Teseo VI platform supports simultaneous operation across multiple satellite constellations, allowing receivers to maintain accurate positioning even when signals from individual satellites are temporarily degraded.
Quad-band GNSS architecture
A key innovation in the Teseo VI generation is its quad-band GNSS architecture, which supports simultaneous reception of signals across the L1, L2, L5, and E6 frequency bands.
Using multiple frequency bands significantly improves positioning accuracy because it allows receivers to correct for signal distortions caused by atmospheric effects. Access to additional signals also improves reliability by increasing the number of satellites that can be tracked simultaneously.
The Teseo VI receiver supports up to 192 signal-tracking channels, enabling the device to process signals from multiple constellations and frequency bands at the same time. This capability improves positioning performance in complex environments such as urban areas, forested regions, or agricultural landscapes with varying terrain.
Improved resilience against interference and spoofing
Reliable positioning is essential for automated agricultural machinery, particularly when GNSS data is used for navigation or machine guidance.
The Teseo VI architecture introduces enhanced anti-jamming and anti-spoofing capabilities designed to protect positioning systems from interference or malicious attacks. Independent processing of signals such as L5, E5a/b, and B2a enables receivers to maintain positioning performance even if one frequency band experiences interference.
The platform also supports authentication mechanisms such as Galileo’s OS-NMA (Open Service Navigation Message Authentication), which allows receivers to verify the authenticity of satellite signals. These capabilities improve the reliability and security of positioning data in applications where system integrity is critical.

Integrated dead-reckoning capabilities
GNSS positioning performance can be affected by temporary signal loss, for example when machinery operates near buildings, under tree cover, or in other environments where satellite visibility is limited.
To address this challenge, STMicroelectronics integrates dead-reckoning capabilities within selected Teseo modules. These systems combine GNSS measurements with data from inertial sensors such as accelerometers and gyroscopes to maintain accurate positioning during short periods of signal interruption.
For example, modules such as the Teseo-VIC6A integrate a six-axis inertial measurement unit (IMU), enabling the system to continue estimating position even when GNSS signals are temporarily unavailable.
This capability is particularly useful for agricultural machines that must maintain precise positioning while operating in challenging environments.
High-performance GNSS modules for industrial systems
STMicroelectronics offers a range of GNSS modules based on the Teseo VI architecture designed for automotive and industrial applications.
Modules such as the Teseo-VIC6A provide quad-band GNSS reception together with integrated sensors, enabling positioning, raw-data output, timing, and dead-reckoning capabilities within a compact module.
For more advanced positioning applications, devices such as the Teseo-ELE6A support positioning software development kits that allow developers to integrate algorithms such as PPP or RTK positioning directly within the module.
These platforms enable developers to design positioning systems tailored to the accuracy requirements of specific agricultural applications.
Simplifying system development
In addition to hardware, STMicroelectronics provides development tools and software resources that simplify the integration of GNSS positioning systems.
The Teseo-Suite software environment allows developers to configure, evaluate, and test Teseo receivers during system development. Evaluation kits are also available for rapid prototyping and testing of GNSS modules within new designs.
These tools allow engineers to accelerate the development of GNSS-enabled products while simplifying system configuration and performance optimization.
Supporting next-generation agricultural positioning
As precision agriculture continues to evolve, positioning technologies are becoming increasingly important for enabling automation, improving efficiency, and supporting data-driven farming operations.
The Teseo VI platform demonstrates how advances in GNSS architecture — including multi-constellation support, multi-band reception, integrated sensors, and enhanced signal processing — can significantly improve positioning performance for industrial and agricultural systems.
