SingularXYZ Z1 Compact RTK GNSS Receiver with IMU Tilt

Compact RTK GNSS Receiver for Accurate Field Measurements

The SingularXYZ Z1 combines professional RTK positioning with a compact, palm-sized housing. It is designed for surveyors, construction teams, engineers, GIS professionals and other field users who need reliable coordinate measurements without carrying a large receiver throughout the working day.

Despite measuring only 107 mm in diameter and 58.7 mm high, the Z1 includes full-constellation satellite tracking, an integrated UHF transceiver, IMU tilt compensation, wireless connectivity and onboard storage. At approximately 547 g, it reduces the weight at the top of the survey pole and is convenient to transport between projects.

Full-Constellation GNSS Tracking

The receiver uses 1,408 channels to track signals from GPS, GLONASS, Galileo, BeiDou and QZSS. Access to multiple constellations and frequencies gives the receiver more satellite observations to work with, helping it establish and maintain an RTK fixed solution in everyday surveying environments.

In practical fieldwork, this is useful when measuring near trees, buildings, machinery or other objects that partially restrict the view of the sky. No GNSS receiver can eliminate the effects of severe signal obstruction or multipath, but broad signal support can improve positioning availability compared with equipment that tracks fewer constellations and frequencies.

Centimetre-Level RTK Positioning

The Z1 is specified for RTK accuracy of 8 mm + 1 ppm horizontally and 15 mm + 1 ppm vertically under suitable operating conditions. It can be used for recording survey points, setting out coordinates, checking site features, mapping assets and collecting accurate spatial data.

The receiver supports several working methods. It can receive network corrections through an internet-connected Android controller using NTRIP, or communicate with another GNSS receiver through its integrated UHF radio. This allows the Z1 to be used as a rover on a local correction network or within a conventional base-and-rover system.

60 Degree IMU Tilt Surveying

An integrated inertial measurement unit allows the survey pole to be tilted by up to 60 degrees while measuring or staking out points. The pole therefore does not have to remain perfectly vertical for every observation.

Tilt surveying is especially practical when the pole tip must be positioned beside a wall, underneath a vehicle, close to stored materials or near another physical obstruction. It can also make routine topographic and construction measurements more comfortable by reducing the need to carefully level the pole before every point.

The IMU is initialized through a short movement of the pole. Once active, the software compensates for the pole angle while the receiver calculates the position of the pole tip.

Base Rover and Network RTK Workflows

The built-in 410–470 MHz UHF radio supports communication between a base receiver and rover. Under suitable open-field conditions, the manufacturer specifies an internal radio range of up to 15 km. Actual range depends on radio settings, antenna position, terrain, interference and local regulations.

For network RTK work, the Z1 connects by Bluetooth to a compatible Android controller running SingularPad. The controller can use its internet connection to receive correction data from a CORS or NTRIP service. This is useful for teams that already have access to a regional RTK network and do not need to establish a local base station for every job.

The receiver can also collect static GNSS observations. Recorded data is stored internally and can be downloaded for conversion and post-processing when the project requires a static workflow.

SingularPad Field Surveying Software

SingularPad provides the field interface for configuring the receiver and completing common survey tasks. Users can create projects, select coordinate systems, measure points, stake out coordinates and manage collected data from a compatible Android controller.

Measured and design data can be imported or exported in commonly used formats. Depending on the selected workflow, supported outputs include formats such as CSV, TXT, KML, DXF and SHP, helping users move field information into CAD, GIS and office-processing software.

Connectivity and Data Management

Bluetooth provides the normal connection between the receiver and field controller, while NFC simplifies initial pairing with compatible equipment. Wi-Fi gives access to the receiver’s browser-based WebUI for checking device information, managing static files, changing settings and installing firmware updates.

A USB Type-C connection is provided for charging and data transfer. The Z1 also includes 8 GB of internal storage, allowing raw observations and project-related data to remain available in the receiver until they are transferred.

Designed for Full Working Days

The internal 4,200 mAh battery provides up to 15 hours of operation, depending on the selected communication mode, radio use and environmental conditions. This is intended to cover a normal working day without adding a large external battery to the survey pole.

The housing carries an IP67 rating for resistance to dust and water. Its specified operating temperature range of −40°C to +65°C supports work across a wide range of outdoor conditions. As with all precision survey equipment, the receiver should still be protected from severe impacts and handled carefully during transport and setup.

Typical Applications

The SingularXYZ Z1 is suitable for a broad range of coordinate-based field tasks, including topographic surveying, construction setting out, boundary and cadastral work, utility mapping, road and infrastructure projects, GIS asset collection and control-point measurement.

• Land and engineering surveys
• Construction layout and as-built checks
• Road, drainage and utility measurements
• GIS asset and feature collection
• Site control for drone mapping projects

Drone pilots can use the receiver to establish or verify ground control points and checkpoints. The Z1 is a ground-based GNSS survey receiver rather than a drone-mounted positioning module.

Choosing the Right Z1 Configuration

A single receiver can be configured as a network RTK rover when a suitable correction service and internet-connected controller are available. Projects without reliable network coverage may require two compatible receivers for a local base-and-rover system. The correct controller, pole, radio antenna, software and correction-service arrangement will depend on the intended workflow.

Global GPS Systems can help buyers select a suitable Z1 configuration for construction, surveying, GIS or drone ground-control work. Configuration guidance and technical support are available for users who need assistance matching the receiver to their local correction service, radio requirements and field software.
