Precision Navigation: Enabling High-Accuracy Alignment for 5G Directional Antennas
1 Introduction: The Challenges of Antenna Alignment in the 5G Era
In 5G network deployment, the installation accuracy of directional antennas directly determines signal coverage quality and network performance. However, current antenna alignment faces several significant challenges:
• Sensitivity of Millimeter-Wave Signals: 5G high-frequency bands (like 28GHz mmWave) are extremely sensitive to directional accuracy, where a 1° deviation can lead to a 30% signal strength loss.
• Complex Urban Environment: Dense high-rise buildings and metallic structures distort traditional magnetic compass readings, resulting in directional errors of up to ±2°.
• Efficiency and Cost Pressure: Operators require single-site deployment time to be compressed within 4 hours, which traditional methods struggle to achieve.
These challenges highlight the industry’s urgent need for high-precision, automated alignment tools. To address this, we introduce the K823E GNSS module, specifically designed for 5G base stations, integrating satellite-level positioning accuracy with deployment efficiency to redefine antenna installation standards.
2 Market Demand: Why GNSS Modules Are Essential
Core Challenge | Limitations of Traditional Methods | Advantages of K823E GNSS Module |
Directional Accuracy (<0.5°) | Magnetic compass interference (±2°) | GNSS unaffected by environment (±0.2°) |
Installation Efficiency (<2 hours) | Manual measurement takes 3-4 hours | Real-time directional output (50% time savings) |
Data Traceability | Prone to errors in manual records | Fully digitalized process logs |
3 Product Highlights: K823E GNSS Module
3.1 Product Overview
The K823E is a compact, high-precision single-frequency positioning and orientation OEM module independently developed by ComNav. It supports GPS, BDS-2, BDS-3, GLONASS, Galileo, and QZSS systems. By integrating GNSS and an accelerometer, the module calculates real-time 3D attitude. During static or low-speed movement, the accelerometer measures gravity acceleration components to determine pitch and roll angles, while GNSS provides precise positioning for yaw (heading) calculation. Advanced sensor fusion algorithms ensure high accuracy and stability, even in dynamic environments.

• RTK Differential Positioning: Base station + rover mode enhances positioning accuracy to 1cm (horizontal) / 2cm (vertical).
• Attitude Fusion Algorithm: Combines dual-antenna baseline calculation and accelerometer data to output true attitude with 0.2°/R resolution.
3.3 Data Parsing: From NMEA to Customized Messages
• $GNGGA: Provides essential positioning data, including time, latitude, longitude, satellite count, and HDOP.
• $GPATT (Proprietary Sentence): Outputs high-precision position, heading, attitude angles, and confidence metrics.
