South ALPS1 Laser Vision IMU RTK GNSS Receiver
The South ALPS1 is an advanced RTK GNSS receiver designed for field teams that need more than standard pole-based measurement. It combines high-precision GNSS positioning with visual positioning, laser measurement, AR stakeout and IMU tilt compensation. In practical fieldwork, this means you can measure more points from safer positions, work around obstacles more easily and complete stakeout tasks with clearer guidance on the controller screen.
This receiver is a strong fit for surveyors, construction professionals, GIS teams, forestry users, UAV mapping crews and infrastructure contractors. It is especially useful on sites where traditional RTK measurement becomes slow or awkward, such as roadsides, embankments, tree-covered areas, narrow spaces, under roof edges, near water or around buildings that block satellite signals.
Measure difficult points with laser and visual positioning
The South ALPS1 uses a 3R green laser to measure target points without placing the pole directly on every point. For construction and surveying teams, this is useful when the point is across a ditch, near traffic, behind an obstacle or in a location where it is unsafe or impractical to stand. The laser also helps in tighter spaces where moving the pole into position takes too much time.
Visual positioning adds another layer of flexibility. The ALPS1 can use image and video data to help capture coordinates for multiple points. Instead of walking to every point individually, users can document the scene and extract measurements more efficiently. This can be valuable for accident scenes, excavation records, urban utility work, road measurements and areas where access is limited.
AR stakeout for clearer field guidance
Stakeout can be one of the most time-consuming parts of fieldwork, especially for less experienced operators or on busy construction sites. The South ALPS1 supports CAD AR stakeout, using its cameras to show design information in relation to the real-world scene. This makes it easier to understand direction, approach the target and complete stakeout work with fewer repeated checks.
The front camera helps users find the general direction from a distance, while the lower camera supports more precise guidance when approaching the final point. For construction layout, road work, utilities and site preparation, this can make the workflow more intuitive than relying only on arrows and numbers.
60° IMU tilt for faster measurements
The built-in calibration-free IMU allows tilted measurements up to 60°. This helps users keep working when the pole cannot be held perfectly vertical, for example near walls, fences, slopes, parked machinery, tree trunks or other obstructions. In day-to-day use, tilt compensation reduces the need to constantly level the pole, helping crews collect points faster while maintaining reliable RTK positioning.
Built for demanding GNSS environments
With 1698 channels and support for GPS, GLONASS, BeiDou, Galileo, SBAS, IRNSS and QZSS signals, the South ALPS1 is designed to maintain strong satellite tracking in varied environments. This is important for users working in urban areas, near buildings, under partial canopy or in changing site conditions where satellite visibility is not always ideal.
The receiver supports RTK through UHF radio and NTRIP, making it suitable for both base-rover workflows and network RTK use. Its internal UHF radio supports 410–470 MHz operation and Farlink protocol, while the 4G modem allows connection to correction services through mobile data. For crews that move between open sites, urban projects and remote locations, this gives flexible ways to receive corrections.
Practical applications
For construction teams, the ALPS1 can support road measurements, site layout, volume-related measurements and general topographic work. The laser function is useful when measuring from a safe distance or when direct access to a point is limited.
For forestry and environmental work, the combination of laser measurement, eccentric measurement and positioning tools can help record tree positions and features without needing to place the pole directly at every point. This can save time in uneven or obstructed terrain.
For UAV mapping and 3D modelling workflows, the South ALPS1 can be used to measure control points, fill data gaps and support field measurements that complement drone data. This makes it useful for drone pilots and mapping teams that need accurate ground data alongside aerial imagery.
Rugged receiver for daily field use
The South ALPS1 is built with a magnesium aluminium alloy shell and IP68-rated protection against dust and water. It is designed for outdoor surveying environments where equipment may face rain, dust, mud, transport vibration and regular field handling. The integrated battery supports long operating times, helping crews complete full work sessions without constantly changing batteries.
Why buy the South ALPS1 from Global GPS Systems
Global GPS Systems supplies professional GNSS equipment to surveyors, contractors, engineers, GIS professionals and drone mapping users worldwide. When choosing a receiver like the South ALPS1, buyers often need more than a specification list. They need to know whether the instrument fits their workflow, correction setup, software and field conditions.
Global GPS Systems can help you compare the South ALPS1 with other RTK GNSS receivers, select suitable accessories and understand how features like laser surveying, AR stakeout, IMU tilt and NTRIP corrections apply to your work. This makes the ALPS1 a strong choice for users who want a modern GNSS receiver with practical tools for faster and safer measurement in the field.
