2. Multi-System and Multi-Band Support

LOCOSYS antennas support multiple satellite systems, including GPS, GLONASS, BeiDou, Galileo, and QZSS. They also provide multi-band compatibility, including:

• L1 Band (1575.42 MHz): The primary frequency for most global navigation systems.
• L2 Band (1227.60 MHz): Enhances positioning accuracy, commonly used in high-precision RTK applications.
• L5 Band (1176.45 MHz): A high-frequency band offering superior anti-interference capabilities, ideal for demanding applications.
• L6 Band (1278.75 MHz): A unique frequency for certain GNSS systems, such as QZSS, enabling high-precision signal transmission.
• L-Band (approximately 1.2 GHz to 1.6 GHz): Provides extensive high-accuracy differential correction signals, such as for PPP applications.

4. Advantages of L1+L5 Dual-Band Antennas

• Balanced Performance and Payload: With a weight of no more than 17 g, the LH-105A2-B is ideal for small- and medium-sized UAVs where payload capacity, flight endurance, and center-of-gravity management are critical.
• Reduced Ionospheric Error: By utilizing both the L1 and L5 frequencies, compatible GNSS receivers can estimate and mitigate ionospheric delay more effectively than single-frequency systems, enabling higher positioning accuracy.
• High-Quality L5 Signal Reception: When paired with an L5-capable receiver, the antenna helps improve positioning stability and measurement quality, particularly in multipath-prone environments.
• Lower Integration Complexity: RF architecture, supported frequency bands, and overall system cost are easier to manage, making it an ideal upgrade for existing L1+L5 GNSS/RTK platforms.
• Well Suited for High-Volume Commercial Applications: Widely applicable to aerial photography, infrastructure inspection, precision agriculture, logistics, FPV and small UAVs, as well as general autonomous aerial platforms.

5. Advantages of L1+L2+L5+L6 / L-Band Full-Band Antennas

• More Multi-Frequency Observations: Simultaneous reception of L1, L2, L5, and other GNSS signals provides greater observation redundancy for RTK processing, helping reduce time-to-fix and improve recovery after signal interruption. Actual performance depends on the receiver, satellite visibility, baseline distance, and positioning algorithms.
• Broader Multi-Constellation Coverage: Supports multiple frequency bands across GPS, GLONASS, Galileo, BeiDou, QZSS, and NavIC, providing greater flexibility in available satellites and signal combinations.
• Support for L6/E6 and L-Band Correction Services: Compatible with receivers supporting QZSS L6, Galileo E6, or satellite-delivered L-Band PPP/SSR correction services, reducing dependence on terrestrial communication links. Service availability varies by region, subscription plan, and receiver capability.
• Designed for Challenging Environments and Mission-Critical Applications: Multi-frequency redundancy improves RTK solution availability in environments such as urban fringes, valleys, forests, or partially obstructed areas. However, the antenna itself cannot eliminate signal blockage or RF interference.
• Future-Proof Platform Upgrade Path: A single antenna platform can support current dual-band, triple-band, and future multi-band GNSS/RTK receivers, helping reduce hardware redesign risks for high-end UAV platforms.

8. Summary

From Cost-Effective Dual-Band Solutions to High-Reliability Full-Band Performance: LOCOSYS Helical GNSS Antennas Deliver More Reliable Precision Navigation for UAVs

As UAVs continue to operate at higher speeds, perform more aggressive maneuvers, fly over complex terrain, and execute longer-range missions, reliable GNSS signal reception has become essential for achieving centimeter-level RTK positioning, autonomous flight control, and safe return-to-home functionality.

LOCOSYS offers both L1+L5 Dual-Band and L1+L2+L5+L6/L-Band Full-Band GNSS helical antenna solutions. The dual-band series combines lightweight design, low power consumption, and excellent cost-performance, making it ideal for high-volume commercial UAV applications such as aerial photography, inspection, agriculture, and logistics. The full-band series expands multi-constellation and multi-frequency coverage to provide greater RTK observation redundancy, improved positioning availability in challenging environments, and compatibility with L6/L-Band satellite correction services, making it particularly suitable for surveying, long-range VTOL platforms, BVLOS operations, and other mission-critical applications.

From compact UAVs to professional surveying platforms, LOCOSYS provides antenna and GNSS/RTK integration solutions tailored to aircraft payload capacity, receiver capabilities, RTK architecture, and operational requirements.

Key Takeaways

• Dual-Band Solution: Upgrade UAV RTK positioning with a lighter, lower-power, and easier-to-integrate dual-band GNSS solution.
• Full-Band Solution: Expand navigation capability through broader multi-constellation support, additional frequency bands, and compatibility with more satellite correction services, delivering higher positioning availability and greater mission resilience for advanced UAV platforms.
