Propesyonal na cloud PPK processing para sa mga survey drone at rovers

Mag-upload ng base at rover files kasama ang camera time-marks upang makakuha ng tumpak na trajectory at exposure coordinates nang walang RTK radio link.

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.

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.

Bakit mas maaasahan ang PPK kaysa sa real-time RTK sa mga isla at kabundukan?

  • Walang pagkaantala dulot ng pagkawala ng cellular o radio link sa pagitan ng base at drone
  • Forward at backward bidirectional Kalman filtering para sa mas matibay na fixed ambiguity solutions
  • Awtomatikong interpolation ng camera exposure time-marks na may antenna offset corrections

Tamang-tama para sa mga drone mapper sa Pilipinas

Madaling iproseso ang mga flight mula sa DJI Matrice 300/350 RTK, Phantom 4 RTK, o Mavic 3 Enterprise sa pamamagitan ng mga lokal na reference station o sariling base.

How to process PPK drone trajectories online

Step-by-step instructions for computing a dual-frequency kinematic baseline on GPS, GLONASS, Galileo and BeiDou, selected per solution, with optional camera-event geotagging.

  1. Upload base and rover observations

    Upload one base and one rover RINEX observation file (.rnx, .obs, .o or .crx, RINEX 2 or 3). Optionally enter the base X/Y/Z coordinates, or let the run use the RINEX header's approximate position instead.

  2. Set elevation mask and mode

    Adjust the elevation mask (0-40°) and, if needed, force SHORT, LONG or AIR processing instead of the automatic 10 km switch.

  3. Add camera events (optional)

    Upload a DJI Timestamp.MRK file or a plain timestamp list to geotag camera exposures, or skip this step and let the run use event epochs already recorded in the rover file.

  4. Run and download

    Submit the job and download the ZIP once it finishes: the .pos trajectory, NMEA, KML, CSV, camera_events.csv and PDF report.

What won't produce a result

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

Rover and base sessions recorded at different times, with no shared window

Overlapping base and rover observation spans: PPK solves the window they share, so a flight with no matching base recording has nothing to resolve against.

Only the rover log, with no base station observation file

A base station RINEX file alongside the rover log. PPK is a differential technique and needs both ends of the baseline to solve a trajectory.

A RINEX header with no INTERVAL field, in a file whose epoch spacing is irregular

A declared sampling interval, or regular enough epoch spacing to infer one. The solving parameters depend on knowing the data rate before a run can be configured.

A rover log that did not track a satellite system selected for the solution

Dual-frequency observations of every selected system in both the rover and the base file. GPS, GLONASS, Galileo and BeiDou are chosen per solution, and a selected system with no satellite common to both receivers and the precise orbit has nothing to resolve against.

A Hatanaka-compressed RINEX-2 observation file saved with the .NNd extension

A .crx Hatanaka file, or a plain uncompressed RINEX observation file. The upload accepts .crx for compressed observations, not the older RINEX-2 .NNd naming convention.

Common questions

Anong mga format ng time-mark file ang tinatanggap?

Tinatanggap ng system ang RINEX event markers, DJI timestamp.MRK files, at standard CSV trigger logs.
