Alpha GEO L100 PRO Rover Base RTK GNSS Set

a-Geo L100 PRO Rover & Base Set for independent RTK fieldwork

The a-Geo L100 PRO Rover & Base Set, also searched for as the Alpha GEO L100 PRO Rover Base Set, is a complete RTK GNSS setup for professionals who want accurate positioning without relying only on an external RTK correction network. By using one receiver as the base and one as the rover, field crews can create their own local correction source on site and continue working in areas where mobile RTK coverage is limited, unavailable or not preferred.

This makes the set a practical choice for land surveyors, construction workers, civil engineers, infrastructure contractors, GIS teams and drone pilots who need dependable coordinates in real field conditions. It is suited for topographic surveys, construction layout, road staking, site control, as-built measurement, utility mapping, ground control points and general RTK positioning work.

Complete base and rover workflow

A rover and base set is useful when you want more control over your RTK correction source. The base receiver is set up over a known or measured point and sends correction data to the rover through the internal UHF radio. The rover then uses those corrections to calculate accurate real-time positions in the field.

For construction teams and survey crews, this is especially helpful on remote sites, new developments, rural projects, road work, earthworks and areas where an RTK network is not available or where a local base station is required for the job. When a correction network is available, the L100 PRO can also be used in Network RTK workflows through its built-in 4G modem.

1408-channel GNSS tracking for reliable satellite availability

The a-Geo L100 PRO uses a 1408-channel GNSS board and tracks GPS, GLONASS, BeiDou, Galileo, QZSS, SBAS and IRNSS. In practical terms, this helps the receiver use a wide range of satellite signals, which can improve availability and stability during normal survey and construction work.

This is valuable when working near buildings, trees, machinery, fences, embankments or other obstacles that can reduce sky visibility. More available satellite signals can help crews keep working with fewer delays when site conditions are not perfect.

120° IMU tilt compensation for faster measuring and stake-out

The Alpha GEO L100 PRO includes calibration-free IMU tilt compensation up to 120°. This allows the operator to measure or stake points without keeping the pole perfectly vertical every time. It is useful around walls, kerbs, trenches, fences, parked machines, vegetation and other obstacles where standing directly over the point is difficult.

For surveyors, this can speed up topo and stake-out work. For construction users, it makes everyday layout and checking tasks easier because the operator can reach difficult points without repeated pole adjustments.

Internal UHF radio and 4G connectivity

The a-Geo L100 PRO Rover & Base Set is built for flexible correction workflows. The internal UHF radio supports local base-rover communication with selectable frequencies in the 410 MHz to 470 MHz range. Under suitable conditions, the specified radio range can reach up to 15 km, although actual range depends on terrain, antenna setup, interference and local regulations.

The built-in 4G modem gives users another option for receiving correction data through mobile networks. This makes the set suitable for both independent local base work and internet-based Network RTK workflows. For companies working across different sites, having both UHF and 4G gives more flexibility from one GNSS set.

WebUI, WiFi and practical field configuration

The receiver can work as a WiFi hotspot and supports WebUI configuration. This allows users to check receiver status, adjust settings and manage static or PPK data through a browser on a compatible phone, tablet or computer. For field crews, this reduces the need for extra cables or complicated setup tools when checking the receiver or downloading data.

Bluetooth and USB-C are also available for everyday connection and charging workflows. This keeps the system practical for teams that need to move between jobs quickly and keep equipment simple on site.

RTK, Static and PPK for different project requirements

The a-Geo L100 PRO supports common GNSS working modes including UHF RTK, Network RTK, Static and PPK. UHF RTK is useful when the base and rover are working together on the same site. Network RTK is useful when a correction service is available through mobile internet. Static and PPK workflows are useful when project requirements call for post-processed GNSS data or when real-time corrections are not the preferred method.

This makes the rover and base set flexible enough for survey companies, contractors and engineering teams that work on different types of projects and cannot always depend on one correction method.

Rugged receiver design for outdoor work

The L100 PRO receiver has a magnesium alloy body, compact dimensions and an IP67-rated housing. It is built for outdoor environments where equipment may be exposed to dust, rain, mud and normal construction-site handling. The receiver is also specified with a 7000 mAh internal battery, USB Type-C fast charging and operating modes suited to long field days.

For crews that carry equipment across a site all day, the compact receiver design helps keep the pole setup manageable while still providing the communication, GNSS and power features needed for professional RTK work.

Who is the a-Geo L100 PRO Rover & Base Set for?

The a-Geo L100 PRO Rover & Base Set is a strong fit for users who need centimetre-level GNSS positioning with the freedom to work from their own base station. Surveyors can use it for topo surveys, control checks and stake-out. Construction teams can use it for site layout, road work, earthworks and as-built checks. GIS users can collect accurate asset and feature positions. Drone pilots can measure ground control points and check points for mapping projects.

It is also a useful option for buyers comparing RTK GNSS equipment under both the a-Geo and Alpha GEO names. The combination of base-rover operation, 1408 channels, 120° IMU tilt, internal UHF radio, 4G, WebUI access and rugged field design gives crews a capable GNSS set for everyday professional positioning work.
