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].

What is CORS network? How to connect to CORS network with external Bluetooth module and mobile phone?

A CORS is a Continuously Operating Reference Station. The CORS is an appealing way to do RTK due to its convenience and large coverage area. While Tersus Precis-BX305 currently does not support build-in NTRIP client feature. An alternative way to connect CORS network is employing external Bluetooth module and a cellphone. Here is a detailed procedure about how to connect to CORS Network with Precis-BX305 board. Demonstration of connecting Precis BX305 to CORS Network Hardware & Software Requirement Precis-BX305 GNSS antenna GNSS antenna cable External Bluetooth module Bluetooth cable Cell phone (android system) 5V DC charger Software required Ntrip client (free android apps) Connect to CORS Network Please follow below steps. Connect GNSS antenna to Precis-BX305. Connect external Bluetooth module to either COM1 or COM2 of the board Connect to power supplier and plug in/turn on the power Turn on the Bluetooth of the mobil...

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...
