Introduction to the Y1 Multi-Frequency GNSS Receiver
The Y1 multi-frequency GNSS receiver is an advanced surveying receiver designed for professional mapping. Using multi-frequency technology and support for all satellite constellations, it delivers outstanding accuracy, speed, and stability in civil engineering, road construction, cadastral surveying, precision agriculture, and industrial surveying projects.
This receiver combines powerful hardware, multiple communication options, and specialized software to provide a complete solution for professional surveying teams.
Full Satellite Support with 1,598 Tracking Channels
One of the most important advantages of the Y1 multi-frequency GNSS receiver is its simultaneous support for all global GNSS constellations.
With 1,598 simultaneous tracking channels, the device receives stable and accurate signals even in urban areas, mountainous regions, and other difficult environments. As a result, RTK fix speed increases and measurement errors are reduced in sensitive projects.
Versatile Connectivity and Fast NFC Pairing in the Y1 GNSS Receiver
The Y1 multi-frequency receiver offers one of the most complete communication packages among surveying receivers:
- Built-in 4G for direct RTK corrections
- Internal UHF radio
- Wi‑Fi
- Bluetooth
- USB
- Serial port
In addition, fast NFC pairing allows the controller to connect with a single tap, without manual searching or complicated setup. This feature saves time and improves field team productivity.
High-Precision IMU and Powerful UHF Radio in the Y1 GNSS Receiver
The Y1 multi-frequency GNSS receiver is equipped with an advanced internal IMU module that enables tilt surveying up to 60 degrees without requiring perfect leveling.
Maintains accuracy within 2.5 cm
Increases point collection speed
Eliminates errors caused by pole tilt
The built-in 2-watt UHF radio also provides communication range of up to 15 kilometers without the need for an external radio.
Rugged Design with OLED Display and Powerful Battery
The Y1 multi-frequency GNSS receiver is designed for durability and performance in harsh working conditions:
- Color OLED display for satellite status, battery, and settings
- IP67 resistance standard (waterproof and dustproof)
- Durable magnesium-aluminum alloy body
- 6600 mAh battery
- More than 20 hours of continuous operation
- Hot-swap battery replacement
These features make the Y1 ideal for long projects and industrial environments.
Why Is the Y1 Multi-Frequency GNSS Receiver a Professional Choice?
If you are looking for an accurate, fast, durable receiver equipped with the latest technologies, the Y1 multi-frequency GNSS receiver is an ideal choice.
Its combination of multi-constellation tracking, advanced IMU, wide connectivity, rugged industrial design, and specialized software makes it a complete solution for professional surveying projects.
