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 chargerSoftware 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 mobile phone and scan and pair the mobile phone with the external Bluetooth device. By default, the external Bluetooth device name is ‘HC-06’ and the default PIN is ‘1234’. You can manually change the device name when you are trying to connect multiple Bluetooth devices.
  • Install NTRIP Client APP from App store and launch this App.
  • Configure Settings->Receiver Settings. Set Receiver Connection as ‘External via Bluetooth’. Set Bluetooth Connection Method as Secure. Tick Auto-Enable Bluetooth.
  • Configure Settings->Ntrip Settings. Launch NTRIP Client and configure the NTRIP Settings as below, then click Connect
    • Network Protocol：NTRIP V1.0
    • Caster IP & Port:
    • Username & Password
    • Data Stream: RTCM32
    • Reported Location: Automatic
As the CORS network may require the approximate location of users, the Ntrip client allows to report the location by automatic or manual way. By automatic means the client read NMEA GGA data from the board and send to Ntrip caster, so the board have to be output NMEA GGA sentences in this way. Failure to report user location may cause connection failure. Alternatively, you can manually report the latitude and longitude to the Ntrip caster.

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 signifi
