Swegeo AA30
Airborne GNSS Antenna
Key Feature
- Swegeo AA30 is a multi-constellation and multi-frequency Airborne GNSS antenna that supports GPS, GLONASS, GALILEO, BEIDOU, QZSS, IRNSS, SBAS and L-Band.
High Gain Reception & Reliable Low-Noise Amplifier for Optimal Satellite Tracking
It is widely used in high-precision navigation and positioning applications in high dynamic environments such as aerospace, UAV, precision agriculture, ADAS, Autonomous Driving where aerodynamics play an crucial role while accuracy and reliability are not sacrificed. Furthermore AA30 is the indoor antenna of TT225 GNSS Re-radiating system.
Enhanced Performance and Precision
Double layer multi-feed point technology ensures high performance on right-hand circular polarization and phase center stability. It further lowers the measurement errors.
Optimized Reception
The overall design provides a high passive gain on low-elevation satellite signal reception so that a higher number of satellites are available for position calculation.
Improved Signal Quality
Pre-filtering on the low noise amplifier effectively suppresses out-of-band interference signals and improves the reliability of the system.
Versatile and Durable
The enclosure is rated IP67 which ensures a reliable performance in any harsh environmental conditions.
UAV and Aerospace Platforms:
The AA30 is a high-performance yet lightweight antenna, making it perfect for drones, UAVs, and even small aircraft. UAV integrators mount the AA30 on survey drones or high-speed mapping UAVs because its aerodynamic, compact design minimizes drag while still capturing all necessary GNSS signals (GPS, GLONASS, Galileo, BeiDou, etc.). In practice, this means a drone can fly longer and more stably, without sacrificing positional accuracy. The antenna’s high gain and low noise amplifier ensure the drone’s RTK receiver maintains a strong fix, even during banked turns or rapid maneuvers. Aerospace engineers have also used AA30 on experimental aircraft and high-altitude balloons, trusting its multi-constellation coverage to provide reliable navigation data in high-dynamic environments.
Precision Agriculture Machinery:
The AA30 finds use on autonomous tractors and farm machinery where a low-profile, durable antenna is needed. Farmers or system integrators can install AA30 on tractor rooftops or UAV crop sprayers; its IP67-rated housing and robust signal reception stand up to dust, rain, and vibration in the field. Thanks to its wide frequency support, an AA30-equipped guidance system can leverage modern satellite correction services (L-Band, SBAS) for improved accuracy in precision planting or variable-rate fertilization. The antenna’s aerodynamic shape is beneficial for machinery that moves quickly or might snag on field obstacles – it’s less likely to be hit by branches and doesn’t add bulk.
GNSS Repeater Systems (Indoor Use):
Interestingly, the AA30 isn’t limited to outdoor use; it also serves as the indoor re-radiating antenna in Swegeo’s TT225 GNSS repeater system. For example, in an aircraft hangar or vehicle garage, an AA30 can be mounted inside to rebroadcast live GNSS signals (fed from an outdoor antenna). Its high gain helps fill the indoor space with satellite signals, allowing testing or initialization of GNSS equipment indoors. This use case showcases the antenna’s versatility and excellent signal handling – it can pick up weak satellite signals outside and, when used in a repeater, help maintain those signals’ integrity for devices under test inside a building.
