Oscar UltimateTilt Test Steps& Results Analysis

1. Tilt Test Steps

1) Configure Oscar Ultimate to rover mode and get a fixed solution.

2) Adjust the pole height; the default pole height is 1.8m in Nuwa.

3) Don't turn on the tilt button; measure a point in the "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.

4) Compare the location of the four points in the "Survey" interface. If they're randomly distributed, and the distance between them is less than 2 cm, it means the pole is normal. If they are very regularly distributed and the distance between them is too large, please measure them 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.

5) Make sure the pole is no problem. Turn on the tilt button in Device-Nuwa

6) The tilt LED on the Oscar Ultimate OLED display lights on with steady red; a few seconds later, it starts flashing red.

7) At this time, walk a few steps ahead, tilt the pole in any direction, then the tilt LED turns

steady green indicates tilt compensation is valid, and the tilt status in Nuwa-Survey will show on.

8) Back to the point, measure it at any angle in any direction. Then move forward for a few meters and back to measure again, repeat 10-20 times.

2. Results Analysis

9) Export the coordinates of these points from Nuwa.

10) Calculate the average value of the four points collected in step 3 and take it as the point's truth value.

11) Compare the values of the tilt measurement points and the truth value. Calculate the dN, dE,dh, 2D error, and 3D error. Then calculate the RMS of them. Here is an example of the results.

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...

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...
