Mr. Stephen Noble, owner of Drone Surveying, used Precis RTK boards to provide land survey and aerial photography service in Australia. By leveraging L1/L2 GPS frequencies for accuracy and reliability, when fixed in RTK or PPK mode, their equipment provides centimeter absolute accuracy. Check it out, click here.

I had my 1st successful flight with a Precis-BX305 mounted on my Multicopter for logging data. I obtained good quality throughout the flight.

With the Precis-BX305, I produced sub-centimeter results using real-time and post processed kinematic in control surveys. Tersus staff have been friendly, helpful and quickly replaced a faulty part. The documentation required to operate the system is all available online depending on your experience there could be a very steep learning curve. I look forward to expanding my business and purchasing newer models from the expanding Tersus range.

I am a software developer in Vietnam, and I have worked in Land Survey for 15 years. In the past I have used Trimble GPS, Hemisphere GPS. And Precis-BX305 can be used as GNSS device with professional survey software like HydroPro, HYPACK as well as routing software in land and sea survey field. It operated smoothly with my system more than I expected.

Mr. Daniel Tampubolon from Institut Teknologi Bandung in Indonesia has done a zero-baseline test of Precis-BX305 for his undergraduate thesis. The test involved 4 GNSS receivers. He used zero-baseline test in order to obtain noise of receiver by single-differencing the raw. Then he found out the characteristic of noise for each receiver by analyzing its spectrum.
Test/Experiment Setup: He connected 4 GNSS receivers: one Ashtech, one Topcon and two Precis-BX305 boards from Tersus (indicating as TerA & TerB in all charts) to one antenna with a one-to-four RF splitter. Then he formed four double different zero baselines between every two receivers and analyzed the quality of the double differenced observations. Part of the results shown in following figure and details could be found here in PDF file.
来自印度尼西亚的Daniel Tampubolon对Precis-BX305板卡进行了零基线测试。 测试涉及4个GNSS接收机。实验设置：他把4个GNSS接收器：一个Ashtech，一个Topcon和两个Tersus的Precis-BX305（在图表中表示为TerA和TerB）连接到一个带有RF分离器的天线。 然后，他在每两个接收器之间形成四个双重不同的零基线，并分析双重不同观测的质量。 下图显示部分结果和详情请查阅PDF文件，请点击。

We have been using the Precis-BX305 GNSS GPS system for unexploded ordnance (UXO) detection projects in Australia, New Zealand and Laos. We have a walking UXO detector with the rover and Precis module receiving GPS corrections and outputting sub decimeter accuracy GPS to our data logging system. The unexploded bombs need to be detected with an accuracy of less than 20 cm, and using the Precis system we have easily achieved this. We are happy with Precis-BX305 GNSS GPS system and its performance.
