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).
How to Use NTRIP Client
- How to start:
- 1Download and install NTRIP Client Download NTRIP Client
- 2Access NMPNT's NTRIP Caster through NTRIP Client
- NMPNT's NTRIP Client
- Select the purpose of use, then access
- Other general purpose (NTRIP Client)
- Host/Port : ntrip.nDGNSS.go.kr / 2101
- ID/PW : nmpnt / nmpnt
- NMPNT's NTRIP Client
- 3Select Mountpoint and receive data
- MountPoint: Observatory name_Data format (e.g., OKCH_RTCM23: Okcheon Monitoring Station’s RTCM2.3)

|
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. |
