Singular XYZ X1 Lite RTK GNSS Rover and Base Set

A Complete RTK Rover and Base Solution

The Singular XYZ X1 Lite Rover and Base Set provides the main equipment needed to establish a local RTK correction source and measure accurate positions with a mobile rover. One X1 Lite receiver is installed over a known or temporary base point, while the second receiver is carried around the site as the rover.

This configuration is useful when a public NTRIP network is unavailable, unsuitable for the project or outside mobile-data coverage. It also gives survey teams greater control over the distance between the base and rover, the correction link and the coordinate system used on site.

The set is suited to land and engineering surveys, construction stakeout, topographic measurement, utility mapping, earthworks, infrastructure projects and drone ground-control surveys.

Two Compact Multi-Constellation Receivers

Each X1 Lite contains a 1,408-channel GNSS engine capable of tracking GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC and SBAS signals. Tracking several satellite systems increases the number of observations available to the base and rover as the satellite geometry changes during the working day.

In practical fieldwork, this helps the equipment operate across open construction sites, roads, agricultural land and partially obstructed areas. Buildings, trees, machinery, multipath and radio interference can still influence performance, so the base should always be positioned where it has a stable mounting point and a clear view of the sky.

Local UHF RTK Corrections

The base receiver can transmit RTK corrections to the rover through its integrated UHF radio. This creates an independent correction link that does not require mobile internet at every measured point.

The X1 Lite operates in the 410–470 MHz range and supports LoRa transmission together with several receive protocols. Under suitable line-of-sight conditions, the internal UHF link has a stated working range of up to 15 km. Real working range depends on antenna height, terrain, buildings, vegetation, interference, radio settings and local regulations.

For projects requiring a stronger or differently configured correction link, the receiver includes an RS232 connection for a compatible external radio. Radio frequency, channel spacing and protocol should be confirmed before combining the equipment with third-party base or rover hardware.

Network Base and NTRIP Workflows

The X1 Lite does not contain an internal cellular modem, but it can be configured as a network base through a suitable 2.4 GHz Wi-Fi connection. In this workflow, the base sends its corrections to an NTRIP service over Wi-Fi instead of transmitting them directly by UHF.

The rover can then receive those corrections through the SC300 controller’s 4G internet connection. This can be useful when the rover must work beyond practical radio range or when terrain and buildings obstruct a direct UHF link.

The system supports NTRIP Client, NTRIP Server, NTRIP Caster and TCP protocols. The exact setup depends on the correction service, network access, field software and available internet connection.

60 Degree IMU Tilt Measurement

The rover’s integrated IMU allows points to be measured with the pole tilted by up to 60°. The operator does not need to centre the pole bubble perfectly for every observation, helping speed up routine point collection and stakeout.

Tilt measurement is particularly useful at building corners, kerbs, fences, trench edges, beneath vegetation and beside parked machinery. It also makes it easier to reach points where positioning a vertical survey pole would be awkward or unsafe.

SC300 Android Field Controller

The included SC300 controller runs Android 12 on an eight-core 2.0 GHz processor with 4 GB of RAM and 64 GB of internal storage. This provides a capable platform for compatible GNSS surveying applications, coordinate files, background maps, CAD data and exported field measurements.

Its 6-inch HD touchscreen provides a clear view of survey maps, point information and stakeout guidance. A physical QWERTY keyboard supports quick entry of point names, feature codes, antenna heights and site notes, including in situations where a touchscreen alone is inconvenient.

Integrated 4G, Wi-Fi, Bluetooth and NFC support field-data transfer and connection to the receivers. The controller’s mobile connection can also provide access to an NTRIP correction service when the rover is operated through the internet.

Static Surveying and Raw GNSS Data

Both receivers include 8 GB of internal storage and can record raw GNSS observations for static surveying and post-processing. Supported formats include RINEX 3.02, RINEX 3.04 and the native XYZ format.

Static observations are useful for establishing or checking survey control, measuring points outside a real-time correction service and completing projects that require post-processed results. Recorded data can be downloaded through the USB Type-C connection or managed through the receiver’s browser-based interface.

Designed for Mobile Field Crews

Each X1 Lite weighs approximately 870 g and measures only 133.5 mm in diameter by 67 mm high. The compact form reduces the weight carried on the rover pole while also making the base equipment easier to transport between projects.

The magnesium-aluminium receiver housing is IP68 rated for protection against dust and water. It is designed to survive a two-metre drop onto concrete and operate across a wide temperature range, making it suitable for regular use on construction sites and outdoor survey projects.

The SC300 is IP67 rated and designed to survive a 1.5-metre drop onto concrete. Together, the receivers and controller form a rugged system for crews that regularly work around rain, dust, mud and changing site conditions.

Battery Capacity for Full Working Days

Each X1 Lite has an internal 6,700 mAh battery with more than 20 hours of stated operating time, depending on the selected mode. The SC300 contains a 7,700 mAh battery with more than 16 hours of stated runtime while the screen is on.

Base-station radio transmission uses more power than ordinary rover operation. For long base occupations or high radio-transmission settings, an external 7–28 V DC supply is recommended to prevent the base battery from becoming the limiting factor during the survey.

Applications for Surveying and Construction

Surveyors can use the set for topographic surveys, site control, detail measurement and setting out. Construction teams can position foundations, utilities, road alignments, drainage features and earthwork designs. GIS and utility professionals can capture accurate asset coordinates, while drone operators can measure ground-control points and independent checkpoints.

• Topographic and engineering surveys
• Construction layout and site verification
• Road, drainage and earthwork projects
• Utility and GIS asset mapping
• Drone ground-control and checkpoint measurement

Configuration and Support from Global GPS Systems

A rover-and-base system must be configured for the project’s coordinate system, base position, correction format and preferred communication link. UHF frequencies and permitted transmission power can also vary by country.

Global GPS Systems can help configure the X1 Lite Rover and Base Set for local UHF, external-radio or NTRIP operation. Support is also available for controller setup, compatible field software and integration with existing surveying equipment.
