Key Feature
The Swegeo GS-980 board offers advanced high-precision RTK positioning, supporting all major GNSS constellations including GPS, BDS, GLONASS, Galileo, and QZSS. Operating across multiple frequencies with a 50Hz RTK data update rate, it ensures comprehensive coverage and real-time accuracy. Additionally, it supports advanced techniques such as Precise Point Positioning (PPP), E6 HAS, and BDS B2b, making it ideal for applications in high-precision surveying, mapping, precision agriculture, and deformation monitoring.
Based on the new generation GNSS SoC – NebulasIV
The board utilizes the latest NebulasIV GNSS System-on-Chip, integrating RF (radio frequency), baseband processing, and high-precision algorithms into a single module for enhanced performance and efficiency.
All-constellation multi-frequency RTK engine and advanced RTK technology
Supports all major GNSS constellations (GPS, GLONASS, Galileo, BDS, QZSS) across multiple frequencies, utilizing advanced RTK technology to deliver precise and reliable positioning.
Instant RTK initialization technology
Enables rapid initialization of RTK positioning, allowing the system to quickly start providing accurate positioning data.
60 dB narrowband interference suppression and interference detection
Features robust narrowband interference suppression up to 60 dB, along with interference detection capabilities to ensure accurate performance in environments with potential signal disturbances.
Heading2 technology to provide orientation information
Includes Heading2 technology for precise orientation and heading information, enhancing applications that require detailed directional data.
STANDALONE single-station high-precision positioning technology
Provides high-precision positioning capabilities as a standalone system without the need for external corrections, suitable for various high-accuracy applications.
Supports B2b-PPP and E6-HAS
Compatible with B2b-PPP (Precise Point Positioning) and E6-HAS (High Accuracy Service), offering additional flexibility and accuracy for demanding positioning tasks.
Geodetic Survey Instruments:
The GS-980 board is often used in high-end surveying receivers for applications like land surveying, construction stakeout, and deformation monitoring. Survey equipment manufacturers embed this board into compact receivers or data-loggers that surveyors mount on tripods. In these scenarios, the board’s multi-constellation, multi-frequency RTK engine yields fixed solutions quickly, allowing surveyors to get reliable coordinates for points or to serve as a local base station broadcasting corrections. The support for PPP (Precise Point Positioning) and Galileo High Accuracy Service (E6 HAS) means in very remote locations, a surveyor could still achieve decimeter or better accuracy without a local base, which is great for geological or boundary surveys far from infrastructure.
Precision Agriculture Base Stations:
Farms and agricultural service providers use GS-980-based receivers as reference stations on large farms. A single GS-980 unit can be set up at the farm to continuously track all satellites and broadcast RTK corrections to tractor autosteer systems across the fields. Its ability to update at 50 Hz and handle all constellations ensures tractor and combine guidance remains smooth and precise, even if one satellite system has outages. Over seasons, the same unit can also perform deformation monitoring of the land (detecting subtle shifts or soil subsidence) thanks to its support for logging high-precision data over long periods.
Structural Health & Deformation Monitoring:
Engineers deploying sensor networks on bridges, dams, or buildings use devices built around the GS-980 for monitoring structural movements. In these systems, the board provides continuous high-precision coordinates of fixed antennas on the structure. If the structure shifts a few centimeters due to stress or environmental factors, the GS-980 will detect it. Its advanced interference suppression is important in such urban or industrial environments, ensuring that nearby radio sources (cell towers, machinery) don’t degrade the signal. The high update rate and accuracy allow for real-time alerts if any unusual movement is detected, supporting preventive maintenance and safety.
