PozStar S5 RTK GNSS Receiver with 60 Degree IMU Tilt

The PozStar S5 is a professional multi-frequency RTK GNSS receiver designed for centimetre-level positioning, surveying, mapping and construction layout. It combines a 1,408-channel GNSS board, an IMU tilt sensor, UHF radio connectivity and Android-based field software in a compact receiver.

The PozStar S5 is designed for land surveyors, construction professionals, civil engineers, mapping specialists, infrastructure contractors and other users who need accurate positioning data in the field.

The receiver can be used for topographic surveys, cadastral measurements, construction stakeout, site positioning, control-point collection, utility mapping, landscape surveys, static GNSS observations and general geospatial data collection.

Yes. The PozStar S5 provides fast RTK positioning and tilt-compensated measurements, making it suitable for setting out points, lines, boundaries and construction elements on active job sites.

Yes. It supports RTK, static and fast-static surveying methods and is intended for professional land-surveying applications that require reliable, high-precision coordinates.

The multi-constellation receiver is designed to maintain reliable satellite tracking in demanding locations such as urban areas, near buildings and beneath partial tree cover. Actual performance depends on satellite visibility, correction quality, interference and local site conditions.

In RTK mode, the specified horizontal accuracy is 0.8 cm + 1 ppm RMS and the specified vertical accuracy is 1.5 cm + 1 ppm RMS. Actual field accuracy depends on the correction source, baseline length, satellite geometry, atmospheric conditions and the surrounding environment.

The PozStar S5 has 1,408 GNSS channels for tracking multiple satellite constellations and frequencies simultaneously.

The receiver supports GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS and NavIC signals. This multi-constellation capability improves satellite availability and positioning reliability.

The specified cold-start time is under 12 seconds and the specified warm-start time is under 4 seconds. RTK fixed-solution time will also depend on the correction service, radio link, satellite conditions and field environment.

The PozStar S5 supports a positioning update rate of up to 20 Hz, allowing coordinate information to refresh rapidly during surveying and stakeout work.

Yes. The receiver supports static and fast-static GNSS surveying and can record data in RINEX static formats for compatible post-processing workflows.

Yes. The built-in MEMS IMU supports tilt-compensated surveying at pole angles of up to 60 degrees, allowing users to measure points without keeping the survey pole perfectly vertical.

Tilt compensation makes it easier to measure building corners, walls, trenches, road edges and other points that are difficult to reach with a vertical pole. It can also improve field productivity by reducing the time spent levelling the pole.

The MEMS IMU is designed to be resistant to magnetic disturbance. Users should still follow the recommended initialization and operating procedures for the best measurement results.

Yes. The PozStar S5 can use NTRIP corrections through the internet connection of a connected Android controller, smartphone or tablet. An active account with a compatible RTK correction provider may be required.

No. The receiver does not have an integrated internet modem. Network RTK corrections are normally received through the mobile-data connection or Wi-Fi connection of the paired Android device.

The PozStar S5 supports an optional 410–470 MHz UHF radio with selectable output power. Radio configuration and permitted frequencies can vary by country, so the correct regional version and local radio regulations should be confirmed before use.

The manufacturer specifies an operating range of approximately 3 to 5 kilometres under suitable conditions. Actual range depends on radio power, antenna height, terrain, obstructions, interference and local regulations.

The PozStar S5 supports RTCM 2.x and RTCM 3.x correction input and output, NMEA 0183 output and RINEX static data formats. Compatibility should be checked when integrating the receiver with third-party radios, software or machine systems.

The receiver is designed to work with PozPad, PozStar’s Android-based field application. PozPad supports survey-data collection, control-point work, mapping input, drawing functions and Bluetooth receiver control.

Yes. The receiver can be operated using a compatible Android smartphone, tablet or field controller connected through Bluetooth. Device and Android-version compatibility should be checked before installation.

Yes. It supports Bluetooth Low Energy 4.1 and 802.11 b/g/n Wi-Fi in access-point mode for receiver control, configuration and data-related functions.

The receiver has 8 GB of internal high-speed memory for recording and storing GNSS survey data.

The built-in 6,700 mAh rechargeable lithium-ion battery provides up to approximately 12 hours of RTK rover operation or up to approximately 18 hours of static operation. Runtime varies with radio use, temperature, connectivity and receiver settings.

The receiver is charged through its USB Type-C port using a suitable 5 V, 3 A power source. The same port can also be used for data download and firmware updates.

Yes. The PozStar S5 has an IP67 ingress-protection rating. It is designed to resist dust and temporary immersion in water to a depth of up to one metre under the specified test conditions.

The receiver is tested to MIL-STD-810H environmental durability standards and is designed to withstand a two-metre drop. Its compact die-cast construction, protective elastomer structure and powder-coated surface are intended for demanding field use.

The specified operating-temperature range is -40°C to +65°C. The specified storage-temperature range is -40°C to +85°C.

The receiver measures approximately 133 × 133 × 89.2 mm and weighs approximately 793 grams, providing a compact and portable design for pole-mounted field surveying.
