PozStar P5 RTK GNSS Receiver with 60 Degree IMU Tilt

PozStar P5 RTK GNSS Receiver

The PozStar P5 is a professional RTK GNSS receiver designed for land surveying, construction setting out, engineering measurement, GIS data collection and other fieldwork that requires accurate coordinates. Its all-in-one housing combines the GNSS antenna, receiver electronics, battery, communications and optional UHF radio capability in a portable unit weighing approximately 825 grams.

With support for multiple satellite constellations and frequencies, the P5 can use a broad range of available GNSS signals rather than relying on GPS alone. This gives surveyors and construction teams more satellite observations to work with, which is particularly useful near buildings, vegetation, machinery and other features that can restrict the view of the sky.

Centimetre-Level RTK Positioning

When receiving suitable RTK corrections, the PozStar P5 provides published horizontal accuracy of 8 mm + 1 ppm and vertical accuracy of 15 mm + 1 ppm RMS. In practical terms, this makes the receiver suitable for tasks such as recording survey points, locating boundaries, checking levels, setting out foundations, positioning utilities and transferring design coordinates onto a construction site.

The receiver can work with network corrections through an internet-connected Android controller or mobile device. It can also be configured for radio-based base and rover operation when the required radio hardware is installed and permitted in the country of use. This gives teams the flexibility to work through an NTRIP correction service or from their own local reference station.

60 Degree IMU Tilt Measurement

The integrated IMU detects the angle and orientation of the survey pole, allowing measurements with the pole tilted by up to 60 degrees. Crews can therefore reach points beside walls, underneath overhangs, at building corners or around site obstacles without repeatedly levelling the pole bubble.

Tilt measurement also makes routine topographic work faster on slopes and uneven ground. The operator can position the pole tip on the required point, maintain normal working movement and record the coordinate once the receiver has a reliable fixed solution. Because the IMU is designed to operate without dependence on a magnetic compass, it is suitable for use around many common metallic objects and construction environments.

Surveying Stakeout and CAD Fieldwork

The PozStar P5 works with the Android-based PozPad field application through Bluetooth. The software provides tools for project creation, coordinate-system configuration, geoid selection, point surveying, point stakeout, line stakeout, site calibration and management of saved working modes.

For construction layout, users can select a design point and follow the displayed direction and distance until the pole reaches the required position. CAD functions support point selection, line-based stakeout, offsets and the creation of points at equal divisions or defined intervals. This helps engineers and setting-out crews work directly from project geometry rather than manually calculating each field position.

PozPad is also designed to display large CAD datasets, making the system useful on infrastructure, road, utility and development projects where drawings contain a substantial number of layers or objects.

Rover Base and Static Survey Modes

The P5 is not limited to a single workflow. It can be configured as an RTK rover for everyday field measurement, as a reference station for transmitting corrections, or as a static GNSS receiver for longer observations and post-processing.

Static observations are stored in the receiver’s internal memory. Users can access recorded files through the Wi-Fi web interface, convert them to RINEX and download them for processing. The same browser interface provides access to receiver status, satellite tracking information and device settings without requiring a direct cable connection.

Field Connectivity and Data Exchange

Bluetooth connects the receiver to the Android field controller, while built-in Wi-Fi provides access to the receiver’s web interface. A USB Type-C port is used for charging, file transfer and firmware updates. The five-pin serial connection supports an external radio and NMEA data output for integration with compatible third-party equipment.

UHF versions support frequencies between 410 and 470 MHz. Radio configuration and permitted transmit frequencies vary by product version and local legislation, so the intended base and rover setup should be checked before ordering.

Battery Life for a Full Working Day

The built-in 6,700 mAh rechargeable lithium-ion battery provides up to 12 hours of operation in RTK rover mode and up to 18 hours during static surveying. This reduces the need to stop and exchange batteries during normal site work. Charging is handled through the USB Type-C connection using a suitable 5 VDC power supply.

Compact and Durable Construction

The receiver measures approximately 135 × 135 × 88.2 mm and weighs around 825 grams. Its compact size keeps the complete pole setup manageable during long topographic surveys, repeated stakeout work and walking inspections.

An IP67 enclosure protects the receiver from dust and temporary water immersion. The housing is designed for field use in construction and surveying environments, with protection against moisture, dirt and everyday handling. As with any precision instrument, correct transport, regular checking and careful maintenance remain important for dependable results.

Who Is the PozStar P5 For?

The PozStar P5 is suited to surveyors who need a flexible RTK rover for topographic measurement, control checks and stakeout. Construction professionals can use it to position foundations, columns, utilities, roads and site features directly from digital coordinates. Engineers can collect as-built information and compare completed work with design data.

GIS teams can use the P5 to capture accurate positions for assets, utilities, inspection points and mapping projects. Drone operators can measure ground-control and checkpoints for photogrammetry, while contractors can use the receiver for general site positioning without relying on traditional tape-based measurements.

Buying and Support from Global GPS Systems

Global GPS Systems can help select the correct PozStar P5 configuration for network RTK, radio rover or rover-and-base operation. Support is available for choosing compatible controllers, poles, radio equipment and correction services, as well as for matching the receiver to local coordinate systems and practical field workflows.

The exact package contents and internal radio configuration can vary. Confirm the required setup before ordering, particularly when the receiver will be used with an existing base station, external radio, NTRIP service or third-party field equipment.
