Giải pháp thay thế RTKLIB trên đám mây, không cần cài đặt

Thực hiện toàn bộ quy trình xử lý dữ liệu GNSS — từ đổi định dạng đến tính toán tọa độ chính xác — trên giao diện web hiện đại.

Processing needs an account. This panel is a first step: it checks your file and needs no account.

Quick check, no account

Upload an observation file or open a sample to see its quality score and key findings.

Choose a RINEX observation file (.rnx, .obs, .crx, .YYo, .YYd, or gzipped)

One file up to 100 MB (20 MB gzipped), ten checks per day. The file is deleted as soon as the result is ready.

Quick question, so we know you are a person

Choose a file first

No file? Use a public station

Bundled sample

Opens a stored example result straight away and does not use one of your daily checks.

Live archive day

Fetches a station's daily observation file from the public archives and checks it. It needs the person check above and uses one of your daily checks.

Station codeDay (UTC)

Between 2010-01-01 and 2026-10-17 (UTC).

Try:

Step-by-step workflow to convert raw GNSS observations and compute precise positioning, with nothing to install.

Convert raw logs with Flux
Upload raw receiver logs to automatically convert to clean RINEX 3 without using command-line CONVBIN.
Inspect data health with Crux
Run multi-GNSS quality scoring to detect cycle slips, multipath, and SNR anomalies before processing.
Compute baseline with Apex
Submit static or kinematic post-processing jobs with automated ephemeris fetching and antenna calibration.
Export results and reports
Download coordinate solutions, inspection charts, and publication-ready PDF reports.

Worth checking before you upload, so a run doesn't cost you credits to tell you what your data was missing.

Base and rover observation files that were not recorded over the same time window

Base and rover logs with an overlapping observation span. A baseline can only be solved for the period both receivers were logging at once.

Only one receiver's log, with no second station to differentiate against

Both a rover log and a base station log. A single-receiver file has no second point to form a baseline against.

A base station whose coordinates are unknown

At least an approximate known position for the base. Without one, the solved baseline vector has no reference frame to be reported in.

Tôi có cần tải thủ công các tệp SP3 và CLK không?

Không. Khác với RTKLIB trên máy tính, PosFlow tự động tìm kiếm và tải về quỹ đạo và đồng hồ chính xác từ các trung tâm phân tích quốc tế.
