Introduction to the X1 Lite Multi-Frequency GNSS Receiver
The X1 Lite multi-frequency GNSS receiver is one of Singular’s professional GNSS receivers, designed for precise surveying, civil engineering, cadastral projects, and RTK operations. With multi-constellation technology, a lightweight design, and complete connectivity, this device delivers fast and stable performance in a wide range of conditions.
By processing multi-frequency satellite signals, the X1 Lite GNSS receiver can reach a fixed position in a very short time. This allows users to perform accurate measurements even in complex urban environments.
The combination of high accuracy, low power consumption, and a rugged design has made the X1 Lite multi-frequency receiver one of the best choices for professional surveyors.
Support for All Satellite Constellations
The X1 Lite multi-frequency GNSS receiver supports all major satellite constellations and can receive and process signals from multiple navigation systems simultaneously.
Thanks to its advanced RTK algorithm and multi-frequency processing system, the X1 Lite multi-frequency GNSS receiver can achieve a fixed and stable position within just a few seconds. This significantly increases surveying efficiency.
The powerful performance of the X1 Lite GNSS receiver remains stable even in challenging environments. Conditions such as multipath reflections, tree canopy, or urban canyons have much less impact on the accuracy of this device.
Compact and Lightweight Design of the X1 Lite Multi-Frequency GNSS Receiver
One of the key features of the X1 Lite multi-frequency receiver is its highly compact design. The device has a diameter of 133.5 mm and a height of 67 mm.
Its weight is only 870 grams, making it much easier to carry during long projects and reducing operator fatigue during fieldwork.
The ergonomic design of the Singular X1 Lite GNSS receiver also helps maintain better pole balance during point surveying, improving overall accuracy.
More Than 20 Hours of Continuous Operation
The X1 Lite multi-frequency GNSS receiver is equipped with a powerful internal battery designed for a full working day. This battery can provide more than 20 hours of continuous operation.
With only 3 hours of fast charging via the Type-C port, the device is ready for use. It can also be charged with a power bank, which is very useful for long field projects.
The internal battery design of the X1 Lite multi-frequency GNSS receiver not only improves safety but also contributes to the device’s waterproof and rugged structure.
Complete Connectivity on the X1 Lite Receiver
The X1 Lite multi-frequency GNSS receiver supports a full range of communication methods so users can easily connect to the device in different conditions.
Its connectivity options include:
- NFC and Bluetooth for quick controller connection
- USB Type-C port for charging and updates
- Built-in Wi‑Fi for web interface access
- TNC connector for the built-in UHF radio
- RS232 port for external radio connection
This variety of communication options gives the X1 Lite multi-frequency GNSS receiver high flexibility in different surveying projects.
High Communication Range in Different Modes
The X1 Lite GNSS receiver can provide a range of up to 15 km when using its internal UHF radio.
With an external radio, this range can increase to 20 km. When connected to CORS networks via the internet, the operational range can extend to more than 50 km.
These capabilities make the X1 Lite multi-frequency GNSS receiver suitable for a wide variety of surveying applications.
Next-Generation IMU Module
The X1 Lite multi-frequency GNSS receiver is equipped with a new-generation IMU module that enables tilt surveying.
The system initializes in just 5 seconds. After that, users can measure points with a tilt angle of up to 60 degrees.
The measurement accuracy in tilt mode is approximately ±2.5 cm, making the X1 Lite multi-frequency GNSS receiver fully suitable for many surveying projects.
Easy Data Download Through the Web Interface
One of the practical features of the X1 Lite multi-frequency receiver is device management through its web-based interface.
Users can connect to the receiver’s internal Wi‑Fi and access the management page to perform tasks such as:
- Downloading static data
- Updating firmware
- Checking device status
- Adjusting receiver settings
This feature makes device management much easier for X1 Lite users.
Rugged IP68 Design of the X1 Lite Multi-Frequency GNSS Receiver
The body of the X1 Lite multi-frequency GNSS receiver is built for harsh environmental conditions. The device features IP68 protection.
This standard means full protection against dust and resistance to water ingress in demanding conditions.
For this reason, the X1 Lite receiver is an excellent choice for use in construction sites, civil engineering projects, and outdoor environments.
SingularPad Surveying Software for the X1 Lite Multi-Frequency GNSS Receiver
SingularPad is an Android-based field surveying software that provides surveying modes such as Static, RTK, and PPK. It supports both Base and Rover operation modes, offers multiple data formats, has a simple and smooth user interface, and provides professional surveying workflows. This software is also used with the X1 Lite multi-frequency GNSS receiver.
