无人机测绘测量应用

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.

无人机应用

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

测绘测量应用

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.

使用Precis-BX305,我通过实时的和PPK(动态后处理技术) 可以得到亚厘米级结果。Tersus的工作人员友好,乐于助人,并迅速更换了一个有问题的配件。与使用板卡和系统相关的用户手册能均能在网上找到。我期待着扩大业务,并从Tersus购买更新的板卡系列。

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.

我在越南从事软件开发,在土地测绘领域已经工作15年。过去,我用的是天宝Trimble和Hemisphere的GPS产品。Precis-BX305可以作为GNSS设备与HydroPro, HYPACK专业级测绘软件及一些土地、海洋测绘领域的规划软件结合使用。该产品能在我的系统上运行顺畅,超出预期。

科研教育应用

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

其他应用

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.

我们在澳大利亚、新西兰和老挝使用Precis-BX305进行未爆弹药检测(UXO)项目。借助可移动的UXO探测器,该探测器上带有流动站及Precis模块接收GPS坐标并输出亚分米精度的GPS数据到记录系统。这些未引爆的物体通常需要检测的精度小于20cm。使用Precis模块,我们能轻松实现,也很满意Precis-BX305的整体表现。
