# Welcome to TraceNav

> SSR-powered RTK corrections, integrated ephemeris, and tooling for every high-precision GNSS workflow

TraceNav is the last RTK corrections service you’ll ever need. We operate a nationwide (CONUS) network that transforms precise State Space Representation (SSR) models into Virtual Base Stations (VBS) for every connected rover. The result: centimeter-level positioning over a single NTRIP connection with built-in assisted GNSS data and automatic datum alignment.

It’s designed for everyone—from farmers, drone pilots, and surveyors to developers integrating high-precision GNSS into robotics, autonomy, or mapping systems.

## What problem does TraceNav solve?

Reliable RTK requires dense Continuously Operating Reference Station (CORS) networks, yet traditional offerings come with:

* **Expensive, centralized infrastructure** — proprietary networks with high subscription costs
* **Limited scalability** — regional CORS networks can’t easily expand across large geographies
* **Coverage gaps** — service typically concentrates in affluent or intensively farmed regions
* **Vendor lock-in & incompatible standards** — divergent data formats, slow RTCM evolution, and closed PPP-RTK tooling

## How TraceNav works

* **SSR-derived VBS** – TraceNav delivers PPP-RTK accuracy by synthesizing virtual bases near every rover using orbit, clock, bias, ionospheric, and tropospheric models.
* **Integrated ephemeris stream** – When a device connects, TraceAssist Ephemeris provides immediate broadcast data; no second mountpoint or connection.
* **TraceRouter orchestration** – Sessions authenticate once, align datums automatically, and can blend with CORS data or your own bases.
* **Open-first tooling** – We extend open projects such as [commaai/laika](https://github.com/commaai/laika) to keep positioning transparent and auditable rather than a black box.

## Who is it for?

* **Agriculture & autonomy** – Tractor guidance, swarm fleets, autonomous ground rigs
* **Aerial operations** – DJI enterprise drones, large-area mapping, precision spraying
* **Survey & construction** – Engineering surveys, machine control, monitoring
* **Developers** – Robotics, logistics, and research teams that need precise GNSS feeds
