BASE SHIFT in Nuwa

In ‘Auto Start’ mode for base station, if the base is moved, or re-started at an unknown point, base shift should be performed to ensure the points collected under the current base station is consistent with that before the base is moved or re-started.

In Nuwa, when performing a base shift, you can choose to use the current base point to calculate the shift amount, or you can choose to use survey point under current base to calculate the shift amount. They are essentially the same, and will apply the shift amount to all the survey points under current base, so that the current plane coordinate datum remains the same as before moving or re-starting.

If the Auto Start base station is re-started at the same location, Nuwa prompts to detect the movement of the base station after the rover is fixed. At this time, the current base station Base1 and the base station Base0 before the restart are used for the calculation. Convert the coordinates of Base0 to control point coordinates, select Base1 as the GNSS point and click [Calculate].

Three Typical Situations of Earthwork Measurement

Three Typical Situations of Earthwork Measurement Tips for earthwork measurement under different circumstances with Tersus Oscar GNSS receiver and NUWA APP Earthwork calculations are essential in many survey projects, but the complexity of measurement and calculations causes many new engineers headaches. In general, earthwork calculation is divided into two parts: excavation and filling, which can also be simply understood as volume and capacity calculation. The following are the Tips for using the Tersus Oscar GNSS receiver and NUWA App for earthwork measurement under different circumstances. The powerful earthwork calculation function of the NUWA app can calculate the result and quickly; you only need to import the survey points and then input the reference altitude. Notes for measurement: When measuring points, we should measure as many points on the surface of the object as possible. The density of survey points needs to be strengthened in places where the terrain changes sig...

Introduction of Nuwa APP's location share function

Today we are going to introduce the Nuwa APP's location share function. It can share the centimeter-level accuracy coordinates obtained from Tersus receiver to other android apps. The following introduction takes a map app as an example. 1. Turn off GPS location on an android device and turn on airplane mode, open a map app and it cannot display any positioning results at this time. 2. Launch Nuwa app, connect a Tersus GNSS receiver, configure the receiver to receive satellite signals and correction data, and ensure the solution status is fixed and high-precision coordinates are displayed. 3. Under the submenu Project -> Settings, turn on [Location Sharing]. 4. After turning on this function, it will automatically jump to the android system setting interface. Find ‘Select mock location app’, click and select Nuwa. 5. Open the map app, it displays the positioning result at this time. Actually this positioning result is the high-precision positioning result of the Tersus receiver ...
