Swegeo HA20
Helical GNSS Antenna
Key Feature
- Fully Frequency & Full Constellation
Swegeo HS10 is a multi-constellation and multi-frequency Helical GNSS antenna with eight-arm coupling and four-feed point technology that supports GPS, GLONASS, GALILEO, BEIDOU, QZSS, IRNSS, SBAS and L-Band.
Superior Satellite Tracking & Stable Phase Center
It fits into any application that requires a small size and lightweight antenna without sacrificing high performance in high-precision positioning, particularly in UAV, pocket-size RTK, handheld/tablet, or other portable system applications.
Reduces The Sources of Measurement Errors
Multi-arm spiral technology ensures high performance on right-hand circular polarization and phase center stability. It further lowers the measurement errors.
Compact & High-Performance Device,
The overall design provides a high gain on low-elevation satellite signal reception so that a higher number of satellites are available for position calculation.
Performs Exceptionally Well
Built-in low-noise amplifier, two-stage filter, good out-of-band suppression strong anti-interference ability provide fully reliable antenna performance in harsh electromagnetic environments.
It is small in size, lightweight, and easy to carry and install.
Handheld Survey Devices & Tablets:
The HA20 is extremely small and lightweight (only ~18 g), so it’s perfect for portable high-precision receivers. Makers of GIS handhelds or survey tablets use HA20 to give their device RTK capability without a bulky antenna. Field professionals—like forestry crews or utility mappers—can carry a tablet outfitted with an HA20 and achieve sub-meter or centimeter accuracy on the go. The helical design means the antenna maintains good satellite visibility even if the device is tilted or the user is moving. Because it doesn’t require a ground plane, a tablet or backpack unit can incorporate it without special mounting, and it will still track all constellations reliably in dense canopy or urban settings, where a small patch antenna would struggle.
Micro-UAV and Small Robot Navigation:
The HA20’s compact form makes it ideal for small drones or robots where every gram matters. A mapping drone the size of a hand or a tiny inspection rover can use HA20 to receive multi-constellation RTK signals, significantly upgrading their navigation precision. Robotics teams choose this antenna to avoid adding weight that would reduce flight time or battery life. Despite its size, the HA20’s multi-feed helical design offers a stable phase center and strong signal gain, so even a micro-UAV performing fast maneuvers can keep lock on enough satellites for RTK. This enables new possibilities like palm-sized drones doing precision surveys in tight spaces or swarms of small robots coordinating with high positional accuracy.
Wearable GNSS Solutions:
Because the HA20 is easy to carry and install, it’s used in emerging wearable applications too. For example, an athlete tracking device or a pedestrian precision navigator might incorporate an HA20 to log exact movement paths. Researchers and athletes can wear a tiny GNSS device (with an HA20 embedded in a cap or on a backpack) to get highly accurate position data for performance analysis or biomechanical studies. The antenna’s durability and IP67 rating ensure sweat or weather won’t interfere, and its ability to maintain performance without a rigid mount means a person can move freely while still obtaining reliable data.
