The Sfaira ONE Plus packs full-constellation centimetre RTK into a slender pocket-sized body. A 1408-channel engine, an upgraded 60° IMU tilt module and a 4800 mAh battery running up to 16 hours keep crews productive anywhere. Paired with a smartphone over Bluetooth, it runs a connected CORS workflow with SingularPad — with no built-in cellular modem, UHF radio, Wi-Fi or NFC.
A powerful 1408-channel GNSS module tracks GPS, BDS, GLONASS, Galileo and QZSS simultaneously, delivering centimetre positioning even in harsh, multipath-heavy environments. The advanced RTK algorithm holds a stable fixed solution when conditions get difficult.
The IMU module initializes in about five seconds and supports tilt surveying up to 60°. After one initialization it keeps the manufacturer’s stated ±2.5 cm accuracy for the whole job, so the pole rarely has to be perfectly plumb on awkward points — a clear step up from the standard Sfaira ONE.
At Φ50 mm × 149 mm and just 409 g, the Sfaira ONE Plus is a true pocket receiver. It slips into a clothing pocket, briefcase or backpack side pocket, so surveyors carry it anywhere the project takes them.
Pair the receiver with a smartphone over Bluetooth 4.0 to configure and survey from one screen. A connected CORS workflow brings network corrections to the pole without a built-in cellular modem, and SingularPad or mainstream survey/GIS software drives the fieldwork.
A 4800 mAh built-in battery delivers about 16 hours of continuous working time. When a day runs long, top it up on the go with a power bank through the Type-C interface — no need to return to the truck.
The Sfaira ONE Plus is distinguished from the standard Sfaira ONE by its upgraded 60° IMU tilt module — not by an invented channel-count upgrade. It carries no internal 4G modem, UHF radio, Wi-Fi, NFC, laser or camera; corrections arrive through a connected-smartphone CORS workflow over Bluetooth.
The Sfaira ONE Plus has no built-in radio or cellular modem. Network corrections reach the pole through a connected-smartphone CORS workflow over Bluetooth, with SingularPad or mainstream survey/GIS software driving the fieldwork.
