Integration with Autopilots

Precis-BX305 board can be integrated with autopilots. In this article, the connecting to Pixhawk flight control is used as an example. A cable is used to connect the COM1 port of Precis-BX305 board and the GPS port of the Pixhawk. It is noticed that the GPS port need a 6pin PicoBlade connector while the COM1 port is a 5pin PicoBlade connector. The pin definition of the Pixhawk GPS port is listed in Table 1. 

With regarding to the power consumption, we recommend using external power sources. Please also pay attention to the baud rate setting of Pixhawk as the default baud rate of Precis-BX305 board is 115200. The Pixhawk can only recognize the NMEA sentence with GP NMEA talker. Incorrect NMEA talker configuration may cause connection failure.

Then you need to mount the GNSS antenna and tether the board on your vehicle. Please beware of following instructions when you mount the GNSS antenna to your drone.
■ Place the module on the outside of your vehicle (in an elevated position if appropriate) with a clear view of the sky
■ Distance the module from DC power wiring and the batteries by at least 10cm

Next step is setting up the Pixhawk with mission planner. Open Mission planner software and choose the right COM port on the top right corner. Choose 115200 as baud rate (default baud rate of Precis BX305 COM1 port). Then click ‘connect button’ on the right. Then the Precis-BX305 is recognized by mission planner if the GPS status becomes ‘3D Fix’.

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...

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...
