Designed for Professional Land Surveying and Mapping Tasks: Suitable for boundary marking, stakeout, grade checking, control point establishment, contouring, earthwork monitoring, as-built verification, and GIS data capture. The receiver’s fast initialization, continuous multi-constellation tracking, and centimeter-level accuracy support high-precision workflows typically associated with professional survey equipment. Centimeter-Level RTK Positioning for Survey-Grade Workflows: Supports real-time kinematic (RTK) corrections through GEODNET to achieve centimeter-level positioning accuracy suitable for boundary surveys, construction layout, topographic mapping, and precision measurement. Typical RTK performance is 8 mm + 1 ppm horizontally and 15 mm + 1 ppm vertically, enabling consistent results across short and medium baselines. Multi-Frequency GNSS with Global Constellation Support: Tracks GPS, GLONASS, Galileo, and BeiDou across L1, L2, and L5 bands for strong satellite availability and improved multipath resistance. Multi-frequency tracking provides faster ambiguity resolution, stable initialization, and reliable positioning in open-sky or partially obstructed conditions. Integrated Helix Antenna for Stable Field Performance: The all-in-one helix antenna design integrates GNSS, Wi-Fi, and Bluetooth into a unified structure that maintains consistent signal strength without external components. This supports surveying tasks in urban corridors, forest edges, or construction sites where stable antenna phase center and uniform reception are important for repeatable measurements. High-Channel GNSS Architecture (Up to 1040 Channels): The tracking engine supports up to 1040 GNSS channels, improving signal acquisition and maintaining RTK lock in challenging environments. The wideband architecture enhances measurement stability during rover movement and provides consistent performance over varying baseline lengths. Reliable Connectivity for Field Operations: Built-in Wi-Fi 802.11 b/g/n and Bluetooth 4.2 enable communication with mobile devices and surveying software. WI-Fi allows straightforward setup of correction services, while Bluetooth supports remote data collection, stakeout visualization, and mapping workflows directly from handheld controllers or smartphones. Intuitive Mobile App for Surveying & GIS Workflows The GEO-MEASURE app provides a streamlined interface for field operations, allowing users to configure GNSS settings, access RTK correction services, monitor satellite status, record survey points, perform stakeout tasks, manage projects, and export collected data to common GIS and CAD formats. Designed for clear usability while supporting advanced parameters needed in professional surveying environments. Field-Ready Power System for Long Survey Sessions: Powered by a 6800 mAh lithium-ion battery that provides up to 24 hours of active operation under standard GNSS use cases. USB-C PD charging (4–8 hours) ensures efficient power management and allows recharging from portable battery packs in field deployments. Rugged IP67 Survey Housing for Outdoor Conditions: Built to withstand common surveying environments with IP67 dust and water protection, shock resistance, and operational performance from –30°C to +65°C. The enclosure resists dust, rain, vibration, and daily handling during site work, boundary marking, or rough-terrain surveying. Compact and Lightweight for Portable Survey Workflows: Measures 71 × 71 × 140 mm and weighs 430 g, supporting all-day handheld use, tripod mounting, range pole deployment, or pack-in/pack-out field operations where mobility is essential. The GEO-MEASURE handheld RTK GNSS receiver is engineered for professional land surveying, construction layout, GIS mapping, and precision measurement tasks requiring dependable, centimeter-level positioning. Leveraging a multi-frequency GNSS architecture, the receiver tracks GPS, GLONASS, Galileo, and BeiDou constellations with up to 1040 channels, maintaining strong satellite geometry and continuous signal availability in open environments, light canopy, and mixed urban conditions. Designed for high-accuracy workflows, the system delivers real-time kinematic (RTK) performance with typical horizontal accuracy of 8 mm + 1 ppm and vertical accuracy of 15 mm + 1 ppm. This supports applications such as boundary surveys, control point establishment, grade checking, construction stakeout, topographic mapping, and geospatial feature collection where consistent positional repeatability is essential. An integrated helix antenna combines GNSS, Wi-Fi, and Bluetooth within a compact form factor, maintaining a stable phase center and consistent signal reception without external antenna components. Multi-frequency tracking improves ambiguity resolution speed, minimizes multipath interference, and enhances initialization reliability across short and medium baselines. These capabilities help maintain RTK FIX status during rover movement and pole-mounte
