Overview of the Services
NTRIP(Network Transport of RTCM via Internet Protocol)
- The conventional differential global navigation satellite system (DGNSS) uses medium-wave media to send global navigation satellite system (GNSS) position error correction signals. In contrast, NTRIP uses the Internet network to send GNSS correction signals.
- RTCM(Radio Technical Committee for Maritime Service)
- GNSS correction signal transmission data format
- RTCM(Radio Technical Committee for Maritime Service)
- It is an applied protocol that uses the Internet to transmit real-time GNSS data.
- NTRIP is capable of wireless access through the mobile IP network based on hypertext transfer protocol (HTTP).
- NTRIP Server
- It transmits NTRIP source data to the NTRIP Caster through the HTTP server.
- NTRIP Caster
- It can distribute data to around 1,000 users simultaneously.
- NTRIP Client
- It transmits DGNSS data using a terminal with Internet access.
- It is capable of using a floating IP network as it uses the Internet (TCP/IP).

Observes the distance through the time observation of the code as radio signals travel from the satellite to the receiver. | Observes the distance by using the phase of a carrier wave existing from the satellite to the receiver. |
