In order to provide survey grade accuracy, Kespry-P connects to a mount point published by a Network positioning service to receive GPS correction.

Network connection details required:

  1. Name of the network

  2. Host name or IP of network

  3. Port 

  4. Username

  5. Password                                                       

Requirements for Service and Mount Point                                                                       

  • Service must be NTRIP compatible.   

  • At least one mount point must be compatible with RTCM 3.0, 3.1, 3.2 or 3.3. The Kespry App does not display incompatible mount points in Network RTK Settings    

  • The mount point should be capable of providing fixed point accuracy of around 2 cm

Requirements for iPad connectivity                 

  • The NTRIP service must be reachable either through WiFi or a cellular network.                      

  • If the NTRIP service is in your intranet and not exposed to the internet, the iPad’s WiFi must join the network which has access to that intranet.

                                                                                               
Questions for Intranet NTRIP service                                                                          

Is the NTRIP caster accessible only on the local intranet?
If Yes, this can be used only if the intranet WiFi is available in the mission area so that the iPad can join the WiFi network.
If No, then it is like any other third party positioning service available on the internet.

What is the IP/host name of the NTRIP caster? 
This is used to fill the “host” field when adding a network service in Kespry app
                                                                                               
What is the port number of the NTRIP caster?
This is used to fill the “port” field when adding a network service in Kespry app
                                                                                               
Do you have at least one mount point which satisfies the requirements listed above?
If No, their service cannot be used.
                                                                                                           
Third-party service                        

  1. Does your service satisfy the service and mount point requirements above?

  2. Do you have the host, port, username and password for their service? Normally, this info is emailed to the subscriber by the service.

  3. Do you know the mount names for which your service provider has given you permission? In many cases, getting access to a service does not mean that you can connect to any mount point published by the service. The service provider will give a list of mount points which the particular user has access to.
