### What is RTKdata.com?

**RTKdata.com** provides **network RTK corrections** for GNSS/GPS receivers via the standard **NTRIP** protocol. Use your existing hardware and field apps to stream **real‑time RTCM** corrections and achieve **centimeter‑level** positioning.

**Who uses RTKdata.com?** Survey & GIS teams · UAV mapping & photogrammetry · Construction & utilities · Agriculture · Research

***

### How it works (60‑second overview)

1. Your app or rover opens an **NTRIP** connection to RTKdata.com.
2. It sends its **approximate position (NMEA GGA)** so the service can localize you.
3. RTKdata.com streams **RTCM** corrections matched to your region/frame.
4. Your receiver converges: **Autonomous → RTK Float → RTK FIX**.

***

### Why RTKdata.com?

* **Fast, precise**: real‑time RTK with typical **centimeter‑level** accuracy in open sky.
* **Works with your tools**: standard **NTRIP**; compatible with popular apps and receivers.
* **Simple setup**: one page of parameters for all devices; clear device/app guides.
* **Global reach**: regional endpoints and a live coverage view to plan field work.
* **Enterprise ready**: guidance for deployment, security/connectivity, and monitoring.

### Concepts you'll see referenced

* **NTRIP & GGA** - why the rover must send **NMEA GGA** to get the right corrections.
* **Baseline & time‑to‑FIX** - distance to the nearest reference affects convergence.
* **Mountpoints** - use **`AUTO`** for regional frames; fixed global frames available if required.
* **Vertical reference** - RTK heights are **ellipsoidal**; apply a **geoid** in GIS/photogrammetry (or on the rover if supported) for **orthometric** elevations.
