• Reach RS4 (Base Station)
• All accessories for the kit

Here are the key features and capabilities of this professional-grade kit:

🌟 Key Features

• High Precision: Offers centimeter-level accuracy (RTK: $7\text{ mm} + 1\text{ ppm}$).
• Multi-band GNSS: Supports all major constellations and signal frequencies, including GPS (L1, L2, L5), GLONASS (L1, L2), Galileo, BeiDou, QZSS, and NavIC. This ensures a fast fix, high reliability, and better performance in challenging environments.
• Tilt Compensation: Both the RS4 Pro and RS4 feature advanced tilt compensation, allowing you to measure points without having to hold the pole perfectly vertical.
• Dual-Camera System (RS4 Pro Rover): The RS4 Pro is the standout, featuring two Full HD cameras for:
  • Visual Stakeout/AR Guidance: Overlaying your designs directly onto the real world for easy stakeout.
  • Measurements from Images: Measuring inaccessible points (e.g., across a busy road or behind a fence) from captured images.

📡 Base and Rover Functionality

• Base (Reach RS4): Used as a fixed station to calculate and transmit correction data.
  • It can transmit corrections via NTRIP over the internet or via LoRa/UHF radio.
• Rover (Reach RS4 Pro): Used for collecting data in the field, receiving corrections from the base or a CORS network to achieve high-accuracy real-time kinematic (RTK) positioning.

💪 Durability and Power

• Rugged Design: Features a lightweight yet durable magnesium alloy body with an IP68 rating (dust and waterproof).
• Extended Battery Life: Provides up to 16 hours of autonomy on a single charge.
• Wide Operating Temperature: Designed to work flawlessly from $-40^\circ\text{C}$ to $+65^\circ\text{C}$.

📱 Software

• The system is powered by Emlid Flow, a complete field and cloud solution for iOS and Android, which manages your entire workflow, project syncing, and data sharing.

This kit is an ideal solution for professionals in surveying, construction, precision agriculture, and drone mapping who need a powerful, feature-rich, and relatively cost-effective high-precision RTK setup.
