Surveying Operations Impact Assessment
Positioning Accuracy
LOW RiskAffected Regions: mid-latitudes, global (minimal)
Expected Impact: Negligible degradation; sub-cm to 1-2 cm accuracy achievable
Accuracy Degradation: <2 cm
RTK GNSS Performance
LOW impactInitialization Time: <1 minute
Network RTK Stability: Stable; correction networks expected to perform normally
Survey Operations
Recommended Methods:
- static
- kinematic
- network_rtk
Session Duration: No adjustments needed; standard sessions recommended
Quality Control:
- Monitor baseline residuals
- Check ionospheric delay gradients
Surveying Operations Recommendations
Immediate Actions
- Proceed with planned surveys using standard procedures
- Monitor space weather alerts for any changes
- Ensure GNSS receivers are updated with latest firmware
Survey Planning
- Schedule critical RTK work during daytime local hours for optimal conditions
- Avoid long baselines >30 km if Kp exceeds 4
- Plan for potential minor delays on 16 Jun due to active periods
Equipment Considerations
- Use multi-constellation receivers for redundancy
- Consider using dual-frequency GNSS for robustness
- Ensure antennas have clear sky view
Field Crew Guidance
- Allow extra initialisation time if Kp >3
- Perform on-site quality checks (e.g., repeat measurements)
- Report any unusual RTK behaviour to office
