SingularXYZ X1 RTK GNSS Rover Base Set with 60° IMU

A complete independent RTK surveying system

The SingularXYZ X1 Rover and Base Set combines two compact X1 GNSS receivers with an SC300 Android field controller. It gives surveyors, construction teams and mapping professionals the equipment needed to establish a local base station and send real-time corrections to a mobile rover.

This configuration is especially useful on sites where no suitable CORS or NTRIP network is available, mobile coverage is unreliable or a project requires corrections from a known local control point. The same receivers can also be configured for network RTK and static GNSS work when project requirements change.

How the rover and base workflow works

The base receiver is installed over a known or newly established reference point. It continuously tracks the available satellites and calculates correction data, which is transmitted to the rover through the integrated UHF radio or an internet-based connection.

The rover applies these corrections while the operator moves around the site, providing centimetre-level coordinates in real time after a fixed RTK solution has been obtained. This allows one crew to collect survey points, check levels and positions or set out design information across the working area.

Full-constellation satellite tracking

Each X1 receiver uses 1408 channels to track signals from GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC and supported SBAS services. Multi-constellation and multi-frequency tracking gives the system access to more satellites throughout the working day.

Greater satellite availability can support faster initialisation and more consistent positioning around partial obstructions such as buildings, trees, machinery and site structures. A clear view of the sky remains important for obtaining the best accuracy and a dependable fixed solution.

Centimetre-level RTK positioning

The X1 has a stated RTK accuracy of 8 mm + 1 ppm horizontally and 15 mm + 1 ppm vertically under suitable operating conditions. Typical RTK initialisation is specified at under five seconds.

In everyday fieldwork, this performance supports topographic surveying, site-control checks, construction layout, utility mapping and accurate ground-control measurement. Final results depend on factors including satellite visibility, base coordinates, radio range, multipath, correction quality and the survey methods used by the operator.

Measure with the rover pole tilted

The integrated IMU enables the rover to compensate for pole angles of up to 60°. Operators can therefore measure a point without carefully centring the pole bubble before every observation.

Tilt compensation is useful beside walls, fences, kerbs, trenches, building corners and other places where the pole cannot be held vertically. It can also speed up high-volume point collection and construction stakeout by reducing the time required to level the pole.

The stated tilt accuracy is better than 2.5 cm within the supported range. Correct pole height, stable handling and good satellite reception remain important for dependable results.

Integrated UHF for local base and rover operation

Both X1 receivers include a 410–470 MHz UHF modem. In a conventional local RTK setup, the base transmits correction data directly to the rover without requiring mobile internet at either receiver.

The enhanced internal radio has a stated working range of up to 15 km under optimal conditions, with selectable transmission power from 0.5 W to 2 W. Actual range depends on terrain, antenna height, vegetation, buildings, interference and local radio regulations.

Radio protocol compatibility should be confirmed before combining the X1 with third-party equipment. SingularXYZ notes that enhanced UHF configurations may not communicate with standard UHF receivers unless the correct compatible option is selected.

Flexible internet and NTRIP communication

The integrated 4G modem allows an X1 receiver to connect directly to an NTRIP or CORS service using a suitable SIM card. The receivers support NTRIP client, NTRIP server, NTRIP caster and TCP workflows.

This gives the set more flexibility than a radio-only system. The rover can use corrections from a regional RTK network, while the base can transmit corrections over the internet when a direct radio link is impractical. Corrections may also be managed through the mobile connection of the field controller.

SC300 Android field controller

The included SC300 provides the user interface for configuring the receivers, creating projects and carrying out survey work. It runs Android 12 and combines an octa-core 2.0 GHz processor with 4 GB of RAM and 64 GB of internal storage.

Its 6-inch touchscreen offers space for viewing maps, point information, satellite status and stakeout guidance. A physical QWERTY keyboard supports reliable data entry when wearing gloves or working in wet and dusty site conditions.

With compatible field software, the controller can be used for coordinate-system setup, point surveys, line and point stakeout, CAD-based fieldwork, coding and COGO calculations.

Suitable for surveying and construction applications

The rover and base set is designed for professionals who need an independent and reusable source of RTK corrections. Surveyors can use it for cadastral, control and topographic measurement, while construction teams can set out design points and verify completed work.

Utility and GIS crews can record accurate asset positions, and drone operators can establish ground-control and independent check points. The system is also suitable for roadworks, earthmoving, drainage, landscaping and infrastructure projects where reliable site coordinates are required.

• Land and topographic surveying
• Construction layout and verification
• Road, utility and infrastructure projects
• GIS and asset data collection
• Drone ground-control measurement

Static GNSS and post-processing workflows

The X1 can record raw satellite observations for static surveying as well as perform real-time RTK work. Supported output includes SingularXYZ binary data and RINEX 3.02 or 3.04 files.

Static observations are stored in the receiver’s internal memory and can be transferred through USB Type-C or downloaded through the browser-based WebUI. This provides an additional workflow for control surveys, longer observations and projects that require office post-processing.

Compact receivers for mobile field crews

Each X1 measures approximately 133.5 mm in diameter by 67 mm high and weighs around 870 g. The lightweight design reduces the load at the top of the rover pole and makes the complete base and rover system easier to transport between sites.

Bluetooth, NFC and Wi-Fi simplify connection and configuration. The WebUI can be used to check receiver status, manage files, change settings and install system updates without relying on specialist desktop software for routine device management.

Long operating time and flexible power

Each receiver contains a 6700 mAh internal battery with a stated operating time of more than 20 hours, depending on the selected work mode. USB Type-C charging and power-bank compatibility make it easier to recharge or extend operation in the field.

Base-station radio transmission increases power consumption. For extended base operation at higher transmission power, an appropriate external power supply can help maintain continuous correction broadcasting throughout the working day.

Built for demanding outdoor environments

The X1 uses a magnesium-aluminium alloy housing with an IP68 rating for protection against dust and water. It is designed to survive a drop of up to 2 metres onto concrete and has a stated operating-temperature range from -40°C to +65°C.

The SC300 controller has IP67 environmental protection for field use. As with all precision survey equipment, the receivers and controller should still be transported securely, protected from avoidable impacts and checked after a serious fall.

Buying and configuration support from Global GPS Systems

Global GPS Systems can help configure the SingularXYZ X1 Rover and Base Set for the intended workflow, including UHF channel settings, regional radio requirements, coordinate systems, NTRIP connections and controller software.

Package contents and radio configurations can vary by region and application. Confirming the required accessories, survey poles, tripods, tribrachs, external power equipment and software licences before ordering helps ensure that the complete system is ready for the intended fieldwork.
