SOUTH Insight V3 Visual IMU RTK GNSS Rover Set

The South Insight V3 Rover Set is a professional multi-constellation RTK GNSS surveying system. It combines the Insight V3 receiver with a South H9 data collector, SurvStar field software, a telescopic survey pole and a controller bracket for centimetre-level positioning, data collection and stakeout work.

The system is designed for land surveyors, construction professionals, civil engineers, utility contractors, GIS teams, mapping specialists and other users who require accurate field coordinates. It can support cadastral surveying, topographic mapping, construction layout, road surveys, utility measurement and infrastructure projects.

The receiver can be used for point collection, topographic surveys, control surveys, point, line and curve stakeout, cross-section and profile measurements, static observations, RTK measurements, PPK workflows, visual positioning and photogrammetric data collection.

Yes. The Insight V3 is suitable for setting out construction points, lines, curves and other design geometry. Its dual-camera AR stakeout system displays visual guidance in the controller software, helping the operator move toward the target efficiently.

Yes. Typical applications include road topographic mapping, control-point densification, profiles, cross-sections, excavation measurement, utility mapping and construction layout. The integrated radio and network RTK options also make it suitable for projects covering large working areas.

Yes. The rover, H9 controller and SurvStar software are designed for single-operator fieldwork. IMU tilt compensation, camera-assisted stakeout, visual guidance and onboard data communications reduce the need for a second person during many measurement and layout tasks.

According to the manufacturer specifications, RTK horizontal accuracy is 8 mm plus 1 ppm when using UHF corrections and 8 mm plus 0.5 ppm when using NTRIP. Specified RTK vertical accuracy is 15 mm plus 1 ppm with UHF and 15 mm plus 0.5 ppm with NTRIP. Actual results depend on satellite visibility, correction quality, baseline length, multipath, atmosphere and field procedures.

Centimetre-level real-time measurements require corrections from a compatible GNSS base station or an NTRIP or CORS correction network. The rover can receive network corrections through its 4G connection or radio corrections through its integrated UHF modem.

Yes. The receiver supports the NTRIP protocol and network models including VRS, FKP and MAC. A compatible correction-service account, mobile-data connection, mountpoint and the correct coordinate-system settings are required.

Yes. Its integrated 410–470 MHz UHF radio can receive corrections from a compatible base station. Supported radio protocols include Farlink, TrimTalk, SOUTH, HUACE, Hi-Target and Satel, although the base and rover must use matching frequencies, protocols and correction settings.

The specified range is typically around 8 km, while Farlink 2.0 can reach approximately 10–12 km under ideal conditions. Terrain, buildings, vegetation, antenna height, interference, radio power and local frequency regulations can significantly affect the practical range.

The specified RTK initialization time is approximately 2–8 seconds under suitable conditions, with general initialization stated as under 10 seconds. Obstructions, weak satellite geometry, radio or mobile-data interruptions and difficult atmospheric conditions may increase the time required.

Dual-camera AR stakeout uses the receiver’s front and downward-facing cameras to display directional guidance over a live field view. In SurvStar, the operator can use this guidance to navigate toward points, lines and curves from a distance and then position the pole accurately at the target.

Visual positioning combines RTK coordinates, camera imagery, photogrammetry and IMU data to calculate coordinates for features visible in photographs or video. It can help measure corners, façades, points beneath roof edges, locations behind obstacles and other targets that are difficult or unsafe to reach directly with the pole.

The manufacturer states that visual positioning can measure points from approximately 10 metres or more in ideal conditions. Achievable distance and accuracy depend on image quality, lighting, target visibility, camera geometry, GNSS status and the data-processing workflow.

The integrated IMU compensates for a pole tilted by up to 60 degrees, allowing the operator to measure without keeping the pole perfectly vertical. This can improve speed when working beside walls, around obstacles, on slopes or at points where conventional pole levelling is inconvenient.

The IMU is described as calibration-free during normal operation. It typically initializes after a few seconds of movement or walking. Good satellite tracking and an RTK fixed solution are still important for reliable tilt-compensated measurements.

Yes. The receiver can collect photographs or video for photogrammetric processing and generate coordinates for multiple visible points. Ground imagery can also help supplement incomplete UAV models, document excavation or accident scenes and support calculations such as distances, areas and volumes when used with suitable processing software.

The 1,698-channel receiver tracks multiple frequencies from GPS, GLONASS, Galileo and BeiDou. It also supports selected QZSS, SBAS, IRNSS and other signals where available, improving satellite availability and positioning performance in demanding environments.

The set includes the South Insight V3 GNSS receiver, a South H9 data collector, SurvStar field software, a telescopic survey pole and a controller bracket. The exact case contents, chargers, cables, antennas and selected accessories should be confirmed in the final set configuration.

The set is supplied for use with South SurvStar field software on the H9 Android controller. SurvStar supports receiver configuration, coordinate systems, point collection, coding, stakeout, road workflows, data import and export, and other surveying functions.

The receiver supports static data formats including STH and RINEX 2.01 and 3.02, RTCM correction formats from RTCM 2.1 through RTCM 3.2, and output formats including NMEA 0183, plane-coordinate data, binary data and Trimble GSOF. Available project import and export formats also depend on the SurvStar workflow.

The receiver has 16 GB of internal storage, automatic cycling storage and support for external USB storage through OTG. Data can be transferred by USB and may also be downloaded through supported FTP or HTTP functions. Receiver status and settings can be accessed through the internal web interface over Wi-Fi or USB.

The built-in 6,800 mAh rechargeable lithium-ion battery is specified for up to approximately 18 hours in rover mode. Operating time varies with radio transmission, mobile-data use, temperature, display use, camera functions and battery condition.

Yes. The receiver has an IP68 dust and water-resistance rating, a magnesium-aluminium alloy housing and a specified operating-temperature range of -45°C to +75°C. It is also designed to withstand a natural two-metre pole drop onto concrete, although protective handling is always recommended.
