Walker 2 Receiver – Ultra-Light and Powerful GNSS RTK Receiver for Professional Surveying

The Walker 2 receiver is an exceptionally lightweight and compact GNSS RTK device, weighing only 220 grams, designed for convenient use in any field conditions. Its sealed and shock-resistant housing withstands drops from heights up to 1.6 meters, ensuring reliability on construction sites, in agriculture, and in challenging terrain.

Despite its small size, Walker 2 is equipped with a high-performance 1408-channel board capable of processing signals from all global satellite systems (GPS, GLONASS, Galileo, BeiDou, etc.) across L1, L2, and L5 frequency bands. This ensures high accuracy and stable positioning even in areas with limited satellite visibility.

An integrated IMU module enables tilt measurements up to 90° without the need for calibration. The system initializes quickly and resists magnetic interference, making it ideal for fast and accurate surveying tasks.

The Walker 2 GNSS RTK receiver is the perfect choice for surveyors, farmers, GIS specialists, engineers, and anyone who needs precise measurements in a compact form factor.

The receiver features 1408 satellite tracking channels and supports all satellite systems and frequencies:

• GPS: L1C/A, L1C, L2C, L2P(Y), L5
• GLONASS: G1, G2, G3
• Galileo: E1, E5a, E5b, E6
• BDS: B1I, B2I, B3I, B1C, B2a, B2b
• QZSS: L1C/A, L1C, L2C, L5
• NavIC: L5
• SBAS: WAAS, EGNOS, MSAS, GAGAN, SDCM

Main Advantages of the Walker 2 GNSS RTK Receiver:

• Multi-Frequency: Supports all existing satellite systems (GPS/GLONASS/Galileo/BDS/QZSS) on L1, L2, and L5 bands, meaning it can deliver accurate positioning nearly anywhere in the world.
• High Accuracy: Equipped with 1408 channels, enabling centimeter-level precision using GNSS corrections from a network or base station. With the built-in IMU, you can measure without a bubble level. Horizontal accuracy: 1 cm, Vertical accuracy: 2 cm.
• Versatile Applications: Supports PPK mode (post-processing survey). Features Bluetooth and 8 GB of internal storage. Ideal for surveying, road construction, power line inspection, land leveling control, CAD applications, and more.
• Portable and Durable: Designed for harsh environments. Weighs only 220 grams and features excellent heat dissipation and IP67-rated water and dust resistance. Can be carried in a shirt pocket or clipped with a metal clip.
• Easy to Use: Connects to Android and iOS devices (with compatible app) to provide professional-grade positioning data. Operates up to 15 hours on a single charge.

RTK Method

The essence of the GNSS RTK method lies in simultaneously receiving satellite signals by a mobile rover at a specific point and a base station at a known static location. The base station detects the difference between computed and actual positions and sends RTK corrections to the rover. The Walker 2 receiver supports flexible configuration for receiving corrections from any available RTK network using the RTCM protocol. GeoMeter offers an efficient solution — connecting GNSS RTK receivers to RTK signals from base station networks. Subscriptions are available for various periods: monthly, quarterly, semi-annually, or annually. The Walker 2 Multi-Frequency GNSS Receiver enables real-time centimeter-accurate surveying.

NMEA Protocol Support

The GNSS RTK receiver uses standard NMEA messages and ensures broad compatibility with all geolocation-enabled software. This provides accurate and reliable coordinate determination.

Productivity Boost

Purchasing the Walker 2 Multi-Frequency GNSS RTK Receiver is a practical investment for significantly increasing your work efficiency: satellite technology allows you to perform far more measurements solo than would be possible with an optical device and a teammate.
