MakeItAccurate will calculate the accuracy you can expect in your processing before you pay and process.

Accuracy depends on the data you have uploaded, the number of satellite constellations tracked, the duration and location of the project.

Australia, New Zealand, the USA and Europe have reliable CORS networks integrated into MakeItAccurate. This manages any datum transformation unknowns and increases the absolute accuracy to 2-3 cm XYZ. MakeItAccurate sources up to 15 reliable CORS stations to add to the integrity of the solution.

Anywhere else in the world you will achieve 5-8cm XYZ precision by applying the clock and orbit corrections. As this is a global system, datum shifts are applied to create coordinates on a given tectonic plate and epoch. This can be considered to be highly precise but may have datum shifts to published coordinates.

In countries where CORS data is not directly integrated, users can upload their own CORS or local base station data to improve the absolute accuracy of their results.

We will automatically perform a QA on your data and provide estimated achievable accuracy report before proceeding with the post-processing.

This estimate takes into account the satellites you have logged, duration of the mission and location of the mission.

Data can be from few minutes’ length to 6 hours for kinematic and up to 24 hours for static data. You will achieve better accuracy with more data, with both kinematic and static. 20 minutes of data is recommended. You will get an accuracy achievable estimate once you upload your data but before you pay and process it.

In countries outside of those listed for hybrid processing, you will achieve high precision, but accuracy can be 4 to 10cm XYZ. As there are no ground stations available in these regions, your data will be processed using our advanced PPP algorithm.

You can add your own base station to improve the absolute accuracy by tying the results to your control.

Our Hybrid Kalman Filtered Terrestrial Multi-Stations and Precise Point Positioning (PPP) algorithm is applied in countries where we have sourced reliable terrestrial CORS data.

These countries are USA, Germany, Spain, France, Austria, Italy, Netherland, Czechia, Belgium, Poland, Portugal, UK and Ireland (partially), Switzerland, Australia, Japan and New Zealand. You will achieve 2-3 cm XYZ absolute accuracy in these countries.

Absolute Accuracy. Differences in X,Y and Z of the MakeItAccurate hybrid post-processing solution compared to results using a local base station. The GNSS data was collected in California, USA, on a KlauPPK full constellation receiver installed on a DJI Matrice210 UAV.
Precision. RMS of observations shown above.


Yes, we do offer a RESTFUL API for streamlining your processing or integrating the solution with your own software or hardware.

No. After post-processing your data will be automatically deleted from our servers.

Our server collects space and ground based satellite correction data 15 minutes after each UTC hour. Your processing will start as soon as this data is available and typically only takes a few minutes.

So, if your survey starts at 10:05 AM UTC time and ends at 10:55 AM then you’d need to either wait 20 minutes (until 11:15 AM UTC) before uploading your data, or you can upload before then and your data will be queued before starting the post processing. You will be notified by email when the processing result is available.


Yes, if you have your local GNSS base station you can add it to the computed solution increase the accurate. This is particularly useful in countries where Hybrid processing is not available.

Yes, kinematic data is supported as well as static. The GNSS data rate can be up to 100hz.

Your antenna type will be automatically detected upon uploading to our service and its phase centre offset will be extracted from the IGS database. If your antenna is not listed in the IGS database then you will have an option to manually specify the phase centre offset of your antenna. Without this the coordinates will be processed with respect to the antenna phase centre which is typically different to the antenna reference point.

Yes, you can select from the list of available geoid models for most countries.


Let us know if there is another geoid model that you need and we’ll add it to the system.

Data can be from few minutes’ length to 6 hours for kinematic and up to 24 hours for static data. You will achieve better accuracy with more data, with both kinematic and static. 20 minutes of data is recommended. You will get an accuracy achievable estimate once you upload your data but before you pay and process it.

You can post-process your DJI Phantom4RTK or M210v2 RTK data to get precise image coordinates for your survey. MakeItAccurate will apply the lever arm correction to determine the camera coordinates for each photo.

You can then use these coordinates either in your desktop photogrammetry software or upload your data to 4DMapper for streamlined cloud-based photogrammetry processing. Your MakeItAccurate login will open your account at Here is a short video showing how to perform photogrammetry processing on your data: []

MakeItAccurate will process your kinematic as well as static GNSS data. Your kinematic (e.g. drone) data can be processed directly in MakeItAccurate with global satellite and terrestrial corrections, enabling base-station-free operations, anywhere in the world.

You don’t need wait until the end of the Julian day to upload and process your data. Corrections are available shortly after the survey, within 15 to 60 minutes.

MakeItAccurate supports higher data rates and full constellation data.

Following formats are supported:
* Trimble .t01, .t02, .t04 , .dat
* Ashtech and Javad .jps and binary files
* Novatel: .bin, .gps, .cdu, .log, .pdc
* Septentrio: .sbf
* U-blox: .UBX
* Topcon: .tps
* Leica: MDB and LB2
* Rinex (2.x or 3.x)
It is recommended to use dual frequency (e.g. L1/L2) multi constellation GNSS receivers for the best possible accuracy.

With our hybrid processing method, your data will be processed using the most recent datum adopted in your country.
the new realization of NAD83(2011) MYCS2 for North America,
ETRF2014 (epoch2010) for European countries,
GDA2020 or GDA94 for Australia, and
NZVDM2000 for New Zealand.

For PPP only processing, the WGS84 datum (G1762 realization) will be used which is almost identical to the ITRF2008 Epoch 2005 datum.

If you have local base station or CORS data on a known datum you can add this to the solution.

You will get highest accuracy with full constellation GNSS data.

You can upload raw GNSS files from Novatel, Trimble, Leica, Topcon, Septentrio, UBlox and generic Rinex format.

In countries where we don’t have automated access to reliable CORS networks.


Yes, MakeItAccurate supports GNSS/IMU data for advanced post processing to produce highly accurate trajectory and attitude data for your LiDAR or mobile mapping projects.

This is in beta release stage and will be enabled in our next production release. If you would like to try the beta release please contact us to share your GNSS/IMU data ensure to process.

IMUs (Inertial Measurement Units) consist of gyro’s and accelerometers that measure change in movement over very small increments of time. The sensors, particularly the gyro’s, drift over time and become very inaccurate.

By applying a synchronized, high precision GNSS trajectory, the drifts in the sensors can be corrected with a process called Kalman Filtering.

With a highly accuracy sensor trajectory and orientation, data produced by hardware such as Lidar scanners becomes inherently more accurate and will achieve better results with less dependency on ground control.
