SOUTH INNO7 RTK GNSS Receiver with IMU

The South INNO7 is a professional multi-constellation RTK GNSS receiver designed for centimetre-level positioning, surveying, mapping and construction work. It combines GNSS tracking, an internal UHF radio, mobile-network connectivity, IMU tilt compensation, onboard data storage and a colour touchscreen in one field receiver.

The South INNO7 is designed for land surveyors, construction professionals, civil engineers, GIS and mapping teams, utility contractors, infrastructure companies and other users who need precise coordinates in the field.

Typical applications include topographic surveys, cadastral and boundary surveys, construction layout, point stakeout, site measurement, earthworks, road and infrastructure projects, utility mapping, control-point measurement and GIS data collection.

Yes. Its internal UHF radio can transmit and receive correction data, allowing the receiver to operate as either an RTK base or an RTK rover when it is configured with suitable field software and accessories.

Yes. The receiver supports NTRIP and common network RTK models, including VRS, FKP and MAC. A compatible SIM card, mobile data connection, correction-service account and field controller are normally required.

It can receive corrections from a compatible CORS or NTRIP network instead of a local base. It also supports selected precise point positioning and correction services, although service availability, subscriptions, initialization time and achievable accuracy depend on the chosen provider and local conditions.

Under suitable RTK conditions, the published real-time kinematic specification is 8 mm + 1 ppm horizontally and 15 mm + 1 ppm vertically. Actual accuracy depends on satellite visibility, correction quality, baseline length, multipath, obstructions, atmospheric conditions and correct field procedures.

The receiver tracks signals from GPS, GLONASS, Galileo and BeiDou. The 1598-channel version also lists support for selected SBAS, QZSS and IRNSS signals, helping provide broad satellite availability in different regions.

The main stated difference is the GNSS board and its number of tracking channels. The 1598-channel version can track a larger set of signals and constellations. The best choice depends on the satellite signals used in your region, your correction service and your required workflow.

The published RTK initialization time is approximately 2 to 8 seconds under good operating conditions. Initialization may take longer where satellite visibility or correction reception is limited.

Yes. Its built-in, calibration-free IMU allows measurements while the survey pole is tilted by as much as 60 degrees. This helps users measure points beside walls, under obstacles, near trenches and in other locations where holding the pole vertically is difficult.

The IMU normally initializes after moving or shaking the receiver for approximately 2 to 5 seconds. The system is designed to resist magnetic interference, but normal movement may be needed to maintain or restore tilt compensation after the receiver has remained stationary.

Yes. It has an internal 410–470 MHz UHF radio with selectable transmission power up to 3 W. It can receive or transmit correction data and can also support radio-router and repeater workflows.

The manufacturer states a typical range of up to 15 km when using the FarLink protocol. Real-world range depends on terrain, antenna placement, radio power, interference, local regulations and whether there is a clear line of sight between the base and rover.

Supported protocols include FarLink, TrimTalk450S, SOUTH, SOUTH+, SOUTHx, HUACE, Hi-Target and Satel. Compatibility should be confirmed when connecting the INNO7 to radios or receivers from another manufacturer.

Yes. The receiver includes a 5G mobile-network module that is backward compatible with 4G and 3G networks. Network operation depends on local coverage, a compatible SIM card, the supported frequency bands and an active mobile data service.

Yes. It supports Bluetooth, Wi-Fi and short-range NFC pairing. Wi-Fi can be used to access the receiver’s web interface, configure settings and exchange correction data, while NFC can simplify pairing with a compatible controller.

The receiver has 64 GB of internal solid-state storage and supports external USB storage. It provides automatic cyclic storage, which removes the oldest files when the available internal memory becomes insufficient.

Yes. The receiver is rated IP68 for protection against dust and water. The published specification states protection from prolonged immersion at a depth of 1 metre, provided all covers, ports and seals are correctly closed and undamaged.

The receiver is specified to withstand a natural 2-metre pole drop onto concrete. Careful handling is still recommended because impact angle, attached accessories and repeated drops can affect the receiver or its calibration.

The published operating-temperature range is -25°C to +65°C, with a storage-temperature range of -35°C to +80°C. Battery performance and operating time may decrease in very hot or cold conditions.

Published battery life is up to approximately 16 hours in static mode, 12 hours in rover mode and 10 hours when operating as an internal-UHF base. Actual runtime varies with radio power, mobile connectivity, screen use, temperature, battery age and receiver settings.

Yes. The South INNO7 uses removable external hot-swappable lithium-ion batteries. Two batteries are included in the listed surveying package, allowing a depleted battery to be replaced to support longer field sessions.

The listed package includes the receiver, two lithium batteries, a battery charger and adapter, a LEMO communication cable, 7-pin-to-OTG cable, 7-pin-to-USB cable, GSM antenna, UHF antenna, 30 cm mounting pole, hard carrying case, measuring tape, tribrach adapter and height-measuring plate. A complete working rover or base setup may also require a survey pole, controller, field software, tripod, tribrach or correction-service access.
