Alpha 4AR Visual GNSS RTK Receiver
The Alpha 4AR Visual GNSS RTK Receiver is a compact RTK receiver designed for both ground surveying and drone positioning. It adds AR real-world stakeout to Alpha's lightweight RTK platform, helping surveyors visually locate target points without relying on traditional pole-shifting methods.
The Alpha 4AR also works as an RTK base station for drone operations. It can provide correction data through NTRIP and standard RTCM output, while its built-in Wi-Fi allows local correction workflows without requiring a cellular network.
With a 400 g body, multi-constellation positioning and built-in WebUI, the Alpha 4AR is designed for teams that need a portable receiver for both ground surveying and UAV operations.
RTKSurvey.com supplies the Alpha 4AR for surveying, construction, mapping and drone positioning applications.
