The Alpha 4i GNSS Rover Set transforms field surveying with its innovative tilt sensor technology and ultra-portable design. Purpose-built for mobile surveyors who demand precision without compromise.

Revolutionary Tilt Measurement

The integrated IMU tilt sensor enables measurements at any angle up to 90°, eliminating the time-consuming process of leveling your rover pole. This breakthrough technology increases productivity by up to 40% while maintaining centimeter-level accuracy, allowing you to measure points that were previously inaccessible or difficult to reach.

Multi-Constellation Precision

The powerful 1408-channel GNSS receiver tracks all major satellite constellations simultaneously, delivering consistent RTK positioning even in challenging environments. Combined with dual communication options—internal UHF radio for 3km range or external radio compatibility extending to 15km—you maintain reliable connectivity across any project site.

Frequently Asked Questions

General

✓ What positioning accuracy can I expect from the Alpha 4i GNSS Rover Set? ▾

The Alpha 4i delivers centimeter-level positioning accuracy with RTK corrections. In optimal conditions with multi-constellation tracking (GPS, GLONASS, Galileo, BeiDou), you can achieve horizontal accuracy of ±8mm + 1ppm and vertical accuracy of ±15mm + 1ppm. The 90-degree tilt sensor maintains accuracy even when the pole is not perfectly vertical.

✓ How does the 90-degree tilt sensor improve field productivity? ▾

The integrated tilt sensor automatically compensates for pole inclination up to 90 degrees, eliminating the need to perfectly level the rover for each measurement. This significantly reduces measurement time and allows for single-person operation in challenging terrain or confined spaces where maintaining vertical pole position is difficult.

✓ What connectivity options are available for RTK corrections? ▾

The Alpha 4i supports multiple connectivity methods including internal 4G LTE modem, Wi-Fi, Bluetooth, and UHF radio. It's compatible with NTRIP correction services and can receive RTK data from base stations or correction networks. The system also supports long-range radio communications for baseline distances up to 20km.

✓ How durable is the Alpha 4i for harsh field conditions? ▾

The Alpha 4i features IP67-rated protection against dust and water immersion, operating reliably in temperatures from -40°C to +65°C. The ruggedized housing is designed to withstand drops and impacts typical in surveying environments. The system includes anti-shock mounting and corrosion-resistant materials for long-term field reliability.

✓ What software compatibility does the Alpha 4i offer? ▾

The Alpha 4i is compatible with major surveying software platforms including Carlson SurvCE, TopSURV, FieldGenius, and MicroSurvey FieldGenius. It supports standard data formats and protocols, ensuring seamless integration with existing workflows and CAD software. The system also includes Alpha's proprietary field software with advanced stakeout and data collection capabilities.
