How TraceVRTK Works
TraceVRTK delivers centimeter-accurate positioning corrections using SSR (State Space Representation) technology. Unlike traditional base station RTK, SSR transmits satellite and atmospheric error models that are customized to your exact location—so you get precision anywhere within coverage, not just near a base.
1
Continuous Monitoring
A network of global and regional reference stations tracks GNSS satellite signals, clock drift, and atmospheric effects in real time.
2
Correction Modeling
These raw measurements are processed into state-space corrections, which precisely describe orbit, clock, ionospheric, and tropospheric errors.
3
Synthetic Base Generation
At your receiver's location, these SSR corrections are transformed into a virtual base station (OSR). This creates a synthetic RTK base exactly where you are, eliminating distance-dependent errors.
4
Real-Time Delivery & Positioning
The virtual base corrections are streamed to your RTK-capable GNSS receiver via NTRIP. Your receiver applies them to its raw satellite data, producing centimeter-level accuracy anywhere in our coverage area.
Additional Services
Expand your precision positioning capabilities with specialized add-on services designed to enhance performance and support diverse workflows.
TraceAssist Ephemeris
Add-onOptional toggle that sends RTCM ephemeris on connection to speed up GNSS initialization and improve reliability. TraceAssist streams standardized ephemeris and clock data for all major constellations, reducing time-to-first-fix.
How It Works
1
Reference Station Monitoring
Our network continuously monitors GNSS satellites, tracking broadcast ephemeris and clock data.
2
Correction Generation
Ephemeris and clock parameters are formatted into RTCM messages (1019, 1020, 1042, 1046).
3
Delivery to Device
Your receiver receives these messages via the same NTRIP connection used for TraceVRTK corrections.
4
Assisted Initialization
The device immediately applies ephemeris data, reducing lock time and improving stability when starting or reacquiring satellites.
Supported Constellations

RTCM 1019 (ephemeris & clock)
GLONASS
RTCM 1020
BeiDou

TraceBack PPK
In DevelopmentPost-processed kinematic service delivering centimeter-level GNSS positioning. Built on the same SSR correction models as TraceVRTK, it applies a PPP with ambiguity resolution (PPP-AR) solver to your logged rover data. Perfect for drone mapping, surveying, agriculture, and research—no real-time link required.
How It Works
1
Log Data
Record rover observations in RINEX or RTCM format during your operation.
2
Upload
Submit logs through the TraceBack interface, with optional event markers or photo logs.
3
SSR Correction generation
TraceBack generates the same orbit, clock, and atmospheric corrections used by TraceVRTK.
4
PPP-AR Solver
Precise point positioning solver with ambiguity resolution processes your data for centimeter accuracy.
5
