How to Check if the Ranging Pole is Normal with Oscar Receiver and Nuwa App?

As we all know, RTK positioning accuracy can reach the centimeter level. If we want to get accurate results, we should make sure to eliminate systemic errors, especially the error caused by the ranging pole. If we were in the field and got inaccurate results, it is likely to be a problem with the ranging pole. Maybe the pole is bent, or the leveling bubble needs to be calibrated. There is a simple way to check whether the ranging pole is normal with Oscar receiver and Nuwa app in the field.

1. Mount the Oscar to the pole, configure it to Rover mode, and get a Fixed solution in Nuwa.
2. Measure a point in "Survey" interface of Nuwa, then keep the pole tip at that point, rotate 90 degrees and measure it again. Repeat three times to get four points in "Point" of Nuwa.
3. Compare the location of the four points in the "Survey" interface. If they're randomly distributed, and the distance between the two of them is around 2 cm, it means the pole is normal. If they are very regularly distributed and the distance between them is too large, please measure four times again for confirmation. If the situation keeps the same, there may be something wrong with the ranging pole, better change to a good one.

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 mobile phone and scan and pai

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 signifi
