Understanding GNSS RTK Accessories: A Field Surveyor Reference
An overview of essential GNSS/RTK accessories, their functions, and what to consider when requesting quotations for your surveying setup.
GNSS and RTK systems rely on a range of accessories to achieve centimeter-level positioning accuracy. Understanding these components helps you build an efficient field setup and make informed purchasing decisions.
Rover Poles
Rover poles position the GNSS antenna at a known height above the survey point. Carbon fiber poles offer the best strength-to-weight ratio, while aluminum poles are more economical. Look for integrated bubble levels and secure locking mechanisms.
Antennas
Multi-frequency antennas (L1/L2 or L1/L2/L5) are essential for RTK accuracy. Ground planes reduce multipath errors, improving position quality in challenging environments.
Radio Links
UHF radio antennas enable RTK correction transmission from base to rover. Consider frequency regulations in your operating region when selecting radio equipment.
Power
Reliable batteries are critical for full-day fieldwork. Always carry spare batteries and confirm compatibility with your specific receiver model before ordering.
Compatibility Note
Always confirm the exact model of your instrument before requesting a quotation. Accessories listed as compatible may have model-specific fitment requirements.
