Could you tell me the different steps to get the position of the antenna (lat, lon, hight)
To choose a method of determining base coordinates, you will need to understand whether your application requires relative or absolute accuracy.
If you need relative accuracy only (for example, for volumetric measurements), you can average base position in Single.
In case the coordinates should be tied to the global coordinates, you will need absolute accuracy. In this case, you should find precise coordinates of the base. To do it, you can use the PPP technique or average base position in Fix using correction from an NTRIP service.
To learn more about different ways to set the base, you can explore our Placing the base guide.
What is CORS method?
Continuously Operating Reference Stations (CORS) constantly gather satellite data to find their coordinates. You can get corrections from CORS via NTRIP to get a precise position of your base. Please note that you will need to request the NTRIP credentials from the CORS operator in your state. To check the nearest CORS, you can explore the map of CORS stations.
What solutions do you recommend for NTRIP caster implementation?
As Michael noticed, available NTRIP services depend on your region. It should be possible to work with a remote NTRIP base in RTK if it meets these requirements:
The distance to the remote base doesn’t exceed 10 km for Reach RS+ and 60 km for Reach RS2
It provides at least RTCM3 messages with an antenna reference point and GPS observables
