The performance of the GNSS RTK Combination Antenna is measured by its ability to provide high-precision positioning via RTK while maintaining reliable communication across the 174~240 MHz and 470~862 MHz bands. Key performance metrics include:

RTK Positioning Accuracy: The antenna’s GNSS component is designed to support RTK technology, delivering centimeter-level positioning accuracy. This is achieved through precise signal reception from multiple satellite constellations (GPS, GLONASS, BDS, GALILEO) and real-time correction data. The omnidirectional pattern ensures that satellites are tracked consistently, even in dynamic environments.

Communication Range: With a gain of 20 dBi, the antenna extends the communication range significantly compared to standard antennas. This allows for reliable data transmission over longer distances, making it suitable for applications such as remote monitoring, where sensors or devices are spread out over large areas.

Signal Integrity: The low VSWR (≤1.5) and high SNR ensure that both positioning and communication signals remain stable and free from distortion. This is critical for applications such as industrial automation, where even small errors in data transmission or positioning can lead to operational failures.

Interference Resistance: The antenna’s filtering components and multi-band design minimize interference between the GNSS RTK and communication bands, as well as from external RF sources. This ensures that positioning accuracy is not compromised by communication signals, and vice versa.

Environmental Robustness: The durable housing and weather-resistant cable allow the antenna to operate reliably in harsh conditions, including rain, snow, extreme temperatures, and high humidity. This makes it suitable for outdoor applications such as agriculture, construction, and public safety.

Compatibility: The 75-ohm impedance, F-head connector, and TV adapter ensure compatibility with a wide range of devices, including RTK receivers, TVs, radios, IoT gateways, and industrial controllers. This versatility reduces the need for additional adapters or modifications, simplifying installation.

These performance capabilities make the GNSS RTK Combination Antenna a reliable choice for applications that require both high-precision positioning and multi-band communication.

Applications: Bridging Positioning and Communication

The GNSS RTK Combination Antenna finds application in a wide range of industries where the integration of positioning and communication is critical. Key applications include:

Smart Agriculture: In precision agriculture, the antenna enables tractors, harvesters, and drones to maintain centimeter-level positioning via RTK while communicating with a central system over the 470~862 MHz band. This allows for precise application of fertilizers, pesticides, and irrigation, as well as real-time monitoring of crop health and equipment status. The VHF band (174~240 MHz) can be used for communication with nearby farm vehicles or emergency services.

Industrial IoT (IIoT): Industrial facilities use the antenna to track the location of assets (such as tools, containers, or vehicles) with RTK accuracy while transmitting sensor data over the 470~862 MHz band. This enables real-time inventory management, predictive maintenance, and process optimization. The omnidirectional pattern ensures that communication is maintained even as assets move throughout the facility.

Public Safety: Emergency services, including police, fire, and ambulance, rely on the antenna for both precise positioning and reliable communication. The RTK capability ensures that emergency responders can locate incidents with centimeter accuracy, while the VHF band (174~240 MHz) provides secure, long-range communication with dispatch centers and other units. The UHF band can be used for connecting to IoT devices such as surveillance cameras or environmental sensors at the incident site.

Broadcast and Media: Broadcast vehicles use the antenna to maintain precise positioning (for coverage mapping) while receiving or transmitting TV signals over the 470~862 MHz band. The F-head connector and TV adapter simplify integration with broadcast equipment, ensuring high-quality signal transmission. The omnidirectional pattern allows for flexible vehicle positioning without signal loss.

Transportation and Logistics: In logistics, the antenna is used in trucks, ships, and delivery vehicles to track their location with RTK accuracy and communicate with logistics management systems over the UHF band. This enables real-time route optimization, delivery tracking, and fleet management. The VHF band can be used for communication with ports, warehouses, or other vehicles.

Environmental Monitoring: Weather stations, wildlife tracking systems, and pollution monitors use the antenna to transmit data over the 470~862 MHz band while recording the precise location of measurements via RTK. This ensures that environmental data is accurately geotagged, enabling detailed analysis and mapping. The antenna’s durability makes it suitable for deployment in remote or harsh environments.

Smart Cities: In smart city infrastructure, the antenna supports applications such as traffic management, where RTK positioning tracks vehicles and traffic lights, and the UHF band enables communication between traffic sensors and control centers. The VHF band can be used for public address systems or emergency alerts, ensuring that information is disseminated quickly and accurately.

These applications highlight the antenna’s ability to bridge the gap between positioning and communication, providing a unified solution for modern, connected systems.
