In the context of CHCNAV's Landstar software, a base shift refers to the adjustment made to correct the position of a GNSS base station after it has been moved or repositioned. This is particularly important to ensure continuity and accuracy in survey data. When a base station is moved, the coordinates of the new position might not align with the original position, leading to potential discrepancies in the survey data. A base shift helps in: 1. **Maintaining Consistency**: By applying a base shift, the software adjusts the recorded coordinates to match the new base station location, ensuring that the survey data remains consistent and accurate. 2. **Data Integrity**: It ensures that the survey points already recorded remain valid and correctly aligned with the new base station position. 3. **Workflow Efficiency**: Reduces the need to re-survey the entire area or manually adjust the coordinates, saving time and effort. To apply a base shift in Landstar software, you typically: 1. Record the new coordinates of the base station. 2. Enter these new coordinates into the Landstar software. 3. The software then calculates the shift and adjusts the survey data accordingly. This feature is crucial for scenarios where the base station needs to be moved due to site conditions or other logistical reasons.
