4. Ọrụ

The SMA26 RTK GNSS system supports various operational modes and applications for precise data collection.

4.1 RTK Connection:

To achieve RTK fixed status, ensure the Rover and Base units are configured with the same protocol and frequency. This can be done via the WEBUI or Bluetooth connection to the Handheld Collector. Alternatively, for Rover operation, you can log in to a CORS (Continuously Operating Reference Station) account on the software to obtain RTK corrections.

Figure 4.1: RTK Communication between Rover and Base.

4.2 Surveying Modes:

The SMA26 supports multiple surveying modes to adapt to different project requirements.

Figure 4.2: SMA26 RTK Surveying Modes.

• Static Surveying: Performs static data collection for high-precision positioning, ideal for control point establishment.
• RTK (Rover+Base): SMA26 acts as both rover and base for real-time kinematic surveying, providing sub-centimeter level accuracy for dynamic survey tasks.
• CORS Network Integration: Connects to Continuously Operating Reference Station (CORS) networks, eliminating the need for a physical base station and offering cost-effective and efficient solutions for large areas.
• SMA26 Rover + SMA20 Base (Static Simultaneously): Combines SMA26 rover with SMA20 static base for enhanced RTK accuracy and reliable communication.
• SMA26 Static + SMA20 PPK: Collects static data with SMA20, enabling Post-Processed Kinematic (PPK) for maximum precision, suitable for environments with poor RTK signal.
• SMA26 Rover PPP: Utilizes Precise Point Positioning (PPP) with Galileo HAS corrections, achieving centimeter accuracy without a base station.

4.3 Software Usage:

The SMAJAYU software on the handheld collector supports multiple languages, measurement units, and various functions for surveying tasks.
