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.

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...

How to Use Oscar to Collect Static Data for A Given Length of Time

Usually, we need to collect static data for a given length of time, for example, 2 hours. In the past, the surveyor had to record the start time and keep an eye on the clock all the time. The function of setting the static collection duration in Oscar GNSS Receiver can solve this problem. When setting the static survey, the surveyor only needs to enter the duration time, then start it, and no more attention will be required. When the time is up, Oscar will automatically stop recording, with no fewer or more data. Now we show you how to set the Oscar static collection duration on the OLED display of Oscar. 1. Turn on the Oscar, press the Power ON/OFF button and Function (FN) button, and go to Mode Config -> Static. The default option of Static is OFF, and you can press the Function (FN) button to switch it to “Auto” or “Manual”. 2. Go to Duration to set the collection time, for example, 120 minutes. 3. Set other options, then choose “Confirm”, and it will start to collect st...
