We can help you navigate the vast range of GNSS antennas available
GNSS antennas help connect IoT devices to the Global Navigation Satellite System (GNSS), a constellation of satellites offering coverage in every location on Earth. GNSS often provides the only alternative in locations where there is no cellular coverage. Challenges with cellular coverage in locations such as dense urban canyons can be addressed by high-precision GNSS, especially with the support of RTK positioning and dead reckoning. A growing range of IoT applications relies on high-precision GNSS to track everything from micromobility vehicles to mining equipment. In applications like precision agriculture, exact positioning can significantly improve yields through accurate monitoring.
This makes GNSS antennas an increasingly crucial part of the IoT. Innovators must however select GNSS antennas carefully to balance minimal signal loss, appropriate sensitivity, and strong signal gain with cost to ensure reliable and precise positioning. For example, a robust antenna design helps in mitigating multipath effects—where signals bounce off buildings or terrain, creating errors in positioning data. The right GNSS antenna can significantly reduce these inaccuracies.
Quectel’s GNSS antennas are designed in various forms to ensure the optimal polarization type for every application. We provide both passive and active antennas to satisfy customer demand for high gain with different installation or connection methods such as pin mount, surface mount, magnetic mount, internal cable and external SMA. Customized connector types and cable lengths are also provided according to requirements.
Performance in challenging environments is another critical factor for GNSS antennas. IoT devices often operate in remote or dense environments not ideal for signal reception, or areas with significant electromagnetic interference. Designers must therefore choose GNSS antennas capable of handling these challenging conditions. Antennas specifically engineered to remain robust against interference and signal degradation enable IoT devices to maintain reliable operations even under adverse conditions.
