GNSS Antennas for Reliable Positioning in Connected Applications

Reliable Positioning Starts with the Right GNSS Antenna

Accurate positioning has become an essential capability in modern connected devices. From vehicle navigation and asset tracking to unmanned equipment, industrial IoT and surveying systems, many applications depend on Global Navigation Satellite Systems to determine location, movement and timing information.

A GNSS antenna is a critical part of this positioning system. It receives satellite signals and delivers them to the GNSS receiver or module for processing. Antenna performance, installation position and integration with the final device can all influence the reliability of satellite signal reception.

BAT Wireless provides GNSS antenna solutions for a wide range of positioning and navigation applications, with multiple antenna structures and configuration options available for different devices and installation environments.

What Is a GNSS Antenna?

GNSS stands for Global Navigation Satellite System, a general term covering satellite-based positioning systems. Depending on the antenna and receiver configuration, GNSS equipment may work with satellite constellations such as GPS, Galileo and other supported navigation systems.

Compared with the commonly used term GPS antenna, a GNSS antenna may be designed to support a broader range of satellite navigation signals. Multi-constellation capability can help positioning devices access more available satellites when used with a compatible GNSS receiver.

The appropriate antenna solution depends on factors such as supported frequencies, device design, antenna location, cable and connector requirements, and the operating environment.

GNSS Antennas for Automotive Applications

Vehicles are one of the most common applications for GNSS technology.

Navigation systems, fleet management terminals, telematics devices, vehicle tracking systems and other connected automotive electronics can use GNSS positioning to determine vehicle location and movement.

In these applications, antenna integration must consider the vehicle structure, installation location and other wireless systems operating nearby. Depending on the project, GNSS may also be integrated with cellular, WiFi or other wireless functions.

For devices requiring multiple wireless technologies, a combination antenna can provide an alternative to installing several separate antennas by integrating multiple antenna functions into one assembly.

Supporting IoT and Asset Tracking

GNSS positioning is also widely used in connected IoT devices.

Tracking terminals, asset management systems, remote monitoring equipment and other connected products may combine GNSS positioning with cellular or other wireless communication technologies. GNSS determines where the device is located, while the communication system transmits positioning or operational data to a remote platform.

This makes antenna selection particularly important for compact IoT devices where installation space can be limited.

BAT Wireless offers different GNSS antenna designs to support a variety of device structures and integration requirements.

GNSS Solutions for Unmanned Equipment

Unmanned systems are another important GNSS application.

Drones, autonomous equipment and other mobile systems may rely on satellite positioning as part of their navigation and control architecture. Reliable signal reception is important when the device operates across changing locations and environments.

The antenna must therefore be selected according to the GNSS receiver, required satellite signals, installation structure and intended operating conditions.

For projects requiring more advanced positioning capabilities, antenna selection should also consider the specific frequency and system requirements of the positioning solution.

Surveying and Precision Positioning

Surveying, mapping and other professional positioning applications can place higher demands on GNSS performance.

These systems may require suitable GNSS antennas to support accurate positioning together with compatible receivers and correction technologies. Antenna placement and surrounding structures are especially important because signal blockage and multipath effects can influence positioning performance.

For this reason, engineers should evaluate the antenna as part of the complete GNSS system rather than selecting it solely according to a single antenna specification.

Marine and Outdoor Applications

GNSS is widely used in marine navigation, outdoor equipment and other applications operating in exposed environments.

For these systems, engineers may need to consider not only RF performance but also antenna housing, mounting method, cable routing and environmental protection.

External GNSS antenna designs can provide flexible installation options where the antenna needs to be positioned away from the main electronics to improve satellite visibility.

The final antenna configuration should always be matched to the actual operating environment.

How to Select a GNSS Antenna

When selecting a GNSS antenna for a new product, several factors should be evaluated together.

First, determine which satellite systems and frequency bands the GNSS receiver supports. The antenna should provide suitable frequency coverage for the intended system.

Second, consider whether the product requires an embedded or external antenna. Available space, device housing materials and installation position can affect this decision.

Cable length and RF connector type are also important for external antenna configurations. These should match the device interface and mechanical design while considering RF signal loss.

Finally, antenna performance should be evaluated within the actual product environment whenever possible. Nearby electronics, metal structures and other antennas can affect real-world reception.
