When it comes to GNSS technology, understanding GNSS antenna types is crucial. These antennas play a vital role in receiving signals from various Global Navigation Satellite Systems, including GPS, Galileo, and GLONASS. In this article, we’ll break down the different types of GNSS antennas and what sets them apart.

Survey antennas are designed for accuracy. “They’re perfect for land surveying,” explains a GNSS expert. “These antennas can provide centimeter-level precision.” Usually, these are used in applications where exact positioning is essential, such as construction and mapping.
Geodetic antennas are similar to survey antennas but are built to withstand harsh environments. “They're used in permanent stations,” mentions a supplier representative. “These antennas can continuously track satellite signals.” This quality makes them ideal for scientific research and geophysical studies.
Next are L1 antennas. “These are the most common type,” states an industry insider. They primarily operate on the L1 frequency, which is standard for GPS. This makes them versatile but also less precise than others. They’re suitable for general navigation tasks.
If you need more accuracy and reliability, dual-frequency antennas are the way to go. “They work on L1 and L2 frequencies,” a GNSS technician explains. “By using two frequencies, they can correct for ionospheric delays.” This results in better performance even in challenging conditions, such as urban environments.
Compact antennas are ideal for portable devices. “They’re lightweight and easy to mount,” a product manager shares. They may not provide the highest accuracy, but they’re great for applications like smartphones and handheld GPS devices. Compact antennas are a perfect option when space is limited.
Embedded GNSS antennas are designed for integration within devices. “These antennas fit directly into smartphones or automotive systems,” states an engineer. Because they are built into devices, they save space and often have a sleek design. However, they might not always offer the best signal reception.
GNSS antennas can be categorized as active or passive, too. “Active antennas amplify the signals they receive,” explains a technical consultant. “On the other hand, passive antennas do not.” This differentiation can influence your choice depending on your application requirements.
With so many GNSS antenna types available, selecting the right one can feel overwhelming. “It all comes down to your specific needs,” advises a GNSS specialist. Think about your application, whether it’s surveying, navigation, or something else entirely. Remember to evaluate the environment too—some antennas perform better in urban areas than others.
