Uchakataji wa kitaalamu wa PPK kwenye wingu kwa droni na wapimaji ardhi
Pakia faili za base na rover pamoja na rekodi za muda wa picha za kamera ili kupata viwianishi sahihi bila kutegemea redio ya RTK.

Opens a stored example result straight away and does not use one of your daily checks.
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.
Kwa nini PPK ni bora zaidi kuliko RTK ya moja kwa moja shambani?
- Hakuna kukatika kwa mawasiliano ya redio au mtandao kati ya kituo cha msingi na droni
- Uchujaji wa pande zote mbili (mbele na nyuma) kwa usuluhishi thabiti zaidi wa utata wa awamu
- Upataji sahihi wa viwianishi vya wakati wa kupiga picha na marekebisho ya umbali wa antena

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.
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.
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.
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.
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
Ni miundo gani ya faili za picha inayokubaliwa?
Mfumo unakubali alama za matukio za RINEX, faili za DJI timestamp.MRK, na kumbukumbu sanifu za CSV.
