SOUTH INNO7 RTK GNSS Rover Base Set with IMU

Independent RTK surveying with a complete base and rover system

The SOUTH INNO7 RTK GNSS Rover Base Set is designed for surveyors, construction crews, civil engineers, GIS professionals and drone-mapping teams that need accurate positioning without depending entirely on a local correction network. One INNO7 receiver is established over a known or newly determined base point, while the second receiver is used as the mobile rover.

The base transmits correction data to the rover through the integrated UHF radio. This gives field teams control over their own RTK setup and makes the system particularly useful on remote sites, large construction projects, rural surveys and locations where mobile-data coverage or an NTRIP service is unavailable.

Complete equipment for base and rover fieldwork

The set includes the principal equipment required to operate a local RTK system: INNO7 base and rover receivers, a SOUTH H6 data collector, SurvStar surveying software, a survey pole, controller bracket, tripod, tribrach and adapter. The tripod and tribrach provide a stable base installation, while the pole-mounted rover and controller allow the operator to move efficiently between survey or stakeout points.

This integrated setup reduces the need to source major components separately and helps ensure that the receiver, controller, field software and mounting equipment are suitable for the same workflow.

Multi-constellation GNSS tracking

Each INNO7 receiver uses a 1,598-channel GNSS board that supports signals from GPS, GLONASS, Galileo, BeiDou, QZSS and supported augmentation systems. Tracking several constellations and frequencies increases the number of usable satellite observations and can improve positioning availability when parts of the sky are obstructed.

Under suitable conditions, the system is specified for RTK accuracy of 8 mm + 1 ppm horizontally and 15 mm + 1 ppm vertically. In practical fieldwork, this supports construction setting out, topographic surveys, utility mapping, earthwork checks, control surveys and accurate as-built measurements.

Fast 60° IMU tilt measurement

The integrated IMU allows the rover pole to be tilted by up to 60° while the receiver calculates the position of the pole tip. Initialization normally requires a short movement lasting approximately two to five seconds rather than a traditional manual calibration routine.

Tilt compensation is useful when measuring building corners, fence lines, trench edges, points beneath overhangs or locations blocked by vehicles and site equipment. Operators can reach the required point with the pole tip while keeping the receiver in a clearer position for satellite tracking.

FarLink UHF communication between base and rover

The INNO7 includes an internal UHF radio operating across 410–470 MHz, with selectable transmission power up to 3 W. SOUTH’s FarLink protocol is designed to transmit the larger correction-data volume produced by modern multi-constellation GNSS tracking while using less power than earlier radio workflows.

The manufacturer states a typical working range of up to 15 km using the internal radio. Actual range will depend on antenna height, terrain, buildings, vegetation, interference, radio settings and local frequency regulations. A base placed in a clear, elevated position will normally provide better coverage than one installed behind obstructions or low to the ground.

Flexible network RTK operation when required

Although the set is equipped for local base-and-rover work, the INNO7 can also operate through an NTRIP or CORS correction service using its cellular communications. This allows the rover to be used independently through a network on sites where coverage is available, while the second receiver remains available for projects that require a local base.

This flexibility is useful for companies that handle a mixture of short urban surveys and longer projects in remote areas. Teams can select the correction method that best suits the site rather than being restricted to one workflow.

SOUTH H6 controller and SurvStar software

The supplied SOUTH H6 data collector is used to configure the receivers, create projects, manage coordinate systems and record field measurements. Mounted on the survey pole with the included bracket, it gives the operator direct access to point information, mapping, coding and stakeout guidance.

SurvStar supports common GNSS survey tasks including point collection, linework, CAD-based stakeout, coordinate management, static observations and data export. These tools make the set suitable for simple construction positioning as well as more structured surveying and engineering workflows.

Touchscreen control and receiver status

Each receiver has a 1.54-inch colour touchscreen for checking operating information and changing common settings directly on the instrument. Operators can monitor satellite tracking, working mode, data links and receiver status without relying exclusively on the controller.

Bluetooth, Wi-Fi and NFC provide additional connection options for compatible controllers and mobile devices. The built-in web interface also supports receiver configuration and status checks through a browser connection.

Storage and operating endurance

The INNO7 includes 64 GB of internal solid-state storage for static observations and receiver data. Cyclic storage management can automatically remove older files when capacity becomes limited, helping prevent data collection from stopping unexpectedly during fieldwork.

The internal battery is specified for approximately 12 hours in rover mode and 10 hours in base mode under the manufacturer’s test conditions. Real operating time varies with radio output, mobile communications, temperature, screen activity and receiver configuration.

Rugged equipment for outdoor projects

The magnesium-alloy receiver housing carries an IP68 rating for resistance to dust and water ingress. The published specification also states resistance to a two-metre pole drop onto concrete under controlled test conditions. This construction is intended for regular use on active building sites, roads, agricultural land and infrastructure projects.

Applications for the SOUTH INNO7 Rover Base Set

The system is suitable for professionals who need to establish their own correction source and work across a defined project area.

• Topographic, boundary and control surveying
• Construction setting out and as-built checks
• Road, bridge and civil-engineering measurement
• Utility, pipeline and asset mapping
• Ground control and checkpoints for drone mapping

Surveyors can use the set for detail collection and stakeout, while construction teams can position foundations, services, kerbs and structural elements from project coordinates. GIS crews can capture assets with centimetre-level positioning, and drone operators can establish accurate ground control points for photogrammetry.

Buying and support from Global GPS Systems

Global GPS Systems can help configure the SOUTH INNO7 Rover Base Set for the required radio frequencies, coordinate reference system and field workflow. Correct base coordinates, antenna heights, correction formats and project settings are essential for dependable RTK results.

Support with receiver configuration, SurvStar setup, radio communication, NTRIP connections and coordinate systems helps teams prepare the equipment for their region and application. The package can also be adjusted when a different controller, software platform or accessory configuration is required.
