Discrepancies in RS2+ accuracy:
- The significant difference in accuracy between RTK and single mode (80+ cm) suggests issues with the single mode configuration or performance. Consider investigating the antenna settings, satellite visibility, and environmental factors.
- While setting up a base station improves accuracy, the significant deterioration at greater distances (90 miles) raises questions about the base station setup and communication effectiveness.
Handheld mapper performance:
- The consistently good accuracy of the handheld mapper (30cm or under) is impressive, especially considering its age and lack of subscription fees.
- The “differential” received by the mapper could indeed be SBAS, which provides additional corrections for improved accuracy.
