AeroStar X1

The AeroStar X1 antenna by LOCOSYS Technology Inc. is capable of
simultaneously receiving signals from GPS L1/L2/L5, GLONASS G1/G2, and BeiDou
B1/B2/B3 frequency bands. It is fully compatible with mainstream GNSS/RTK boards
and modules both domestically and internationally. Utilizing high-precision triplefrequency
positioning, it is plug-and-play ready and easily achieves sub-meter accuracy.
When integrated with ground-based augmentation systems (SBAS), it supports RTK
functionality to provide centimeter- to millimeter-level positioning precision.

Developed and rigorously tested by LOCOSYS Technology Inc., a leading
provider of GNSS and positioning solutions based in Taiwan, the AeroStar X1 benefits
from decades of expertise in satellite navigation, RF circuit design, and high-frequency
antenna engineering. LOCOSYS is renowned for its strong R&D capabilities and has
delivered GNSS modules, antennas, and integrated solutions to global markets across
Europe, North America, and Asia. By combining in-house hardware development with
firmware and algorithm innovation, LOCOSYS ensures optimal signal quality and
stability, even in the most challenging environments.

This antenna is widely applicable in aerospace, precision agriculture, vehicular
positioning, autonomous navigation, and surveying applications that require stable and
accurate GNSS data. As the demand for precise positioning continues to grow across
industries, antennas like the AeroStar X1 play a crucial role in enabling nextgeneration
applications such as:

Unmanned Aerial/Ground/Marine Vehicles (UAV/AGV/UGV)
High-reliability GNSS reception is essential for flight control, autonomous
navigation, and aerial mapping. The antenna’s wide-beam coverage and minimal
phase center variation make it an ideal choice for UAVs or mobile platforms.

Smart Agriculture and Agricultural Machinery
When integrated with GNSS RTK solutions, farmers can achieve centimeter-level
accuracy in planting, spraying, and harvesting, greatly improving efficiency and
productivity.

 Autonomous Vehicles and ADAS
The combination of L1/L2/L5 signals enhances multipath resistance and
positioning robustness in urban and semi-obstructed environments—key to the
safety of autonomous driving systems.

Land Surveying, Infrastructure Monitoring (e.g., dams, bridges, landslides)
High-precision antennas are indispensable for collecting reliable and repeatable
geospatial data in topographic surveys and GIS applications.

Timing and Infrastructure Synchronization
In telecommunications, power grids, and LEO satellite systems, accurate GNSS
timing provided by such antennas is critical for network stability and fault
diagnostics.

By leveraging high zenith gain, wide-angle circular polarization, and millimeterlevel
phase center stability, LOCOSYS ensures uncompromised performance even in
GNSS-challenging conditions such as urban canyons, forested regions, or obstructed
terrains. As autonomous systems and IoT deployments continue to evolve, LOCOSYS
remains committed to delivering scalable, rugged, and high-performance GNSS
antenna solutions to meet the growing demand for reliable, real-time, and multi-band
precision positioning.

Features

High Zenith Gain & Wide Beamwidth
The antenna provides high gain at the zenith and features a wide-beam radiation
pattern with wide-angle circular polarization. These characteristics ensure
excellent reception of low-elevation signals, allowing reliable satellite tracking
even in partially obstructed environments.

Multi-feed Point Design
A multi-feed point architecture ensures the phase center aligns closely with the
geometric center of the antenna, minimizing measurement errors. The phase
center variation (PCV) is controlled within millimeter-level tolerances.

Advanced ESD & Surge Protection

The antenna incorporates a proprietary electrostatic discharge (ESD) and lightning
protection circuit with over-voltage protection. A high-performance out-of-band
filter is integrated to ensure robust operation even under harsh electromagnetic
interference (EMI) conditions.

Ruggedized Mechanical Design
The radome is constructed from UV-resistant, high-strength ABS material with an
IP67 waterproof rating. The base is made of titanium-aluminum alloy, significantly
reducing overall antenna weight without compromising structural integrity.

Low Noise Amplifier (LNA) Design
The antenna's LNA employs a dual-stage filtering scheme. Incoming signals are
first filtered to suppress out-of-band interference and then amplified. This design
minimizes the risk of amplifier saturation and enhances the overall reliability of the
GNSS system.
