ApplanixPPK - Your One-Stop Tool For Higher Precision Positioning Data
ApplanixPPK is an easy-to-use Web App Cloud Service to post-process kinematic Differential GNSS position for UAVs and drones. The ApplanixPPK Cloud processing runs the GNSS trajectory refinement which supports your drone mapping application.
All you need is Rinex data from the drone and a base station to generate a highly accurate trajectory. No base station available? Use the SmartBase concept. Add the images and the exposure time stamps to produce a file ready for photogrammetric mapping jobs. Try it now for free!

Frequently Asked Questions
+ What is ApplanixPPK?
ApplanixPPK is a Web App Cloud Service to post-process kinematic position for UAVs and drones. It will process a GNSS trajectory based on Rover Rinex and Base Rinex Data. In addition, it will provide the EO parameter for imagery, if exposure time stamps are available and converted to a PhotoID file (Photo Number, Exposure Time). The creation of the PhotoID file can be done right in the Web App.
ApplanixPPK combines POSPac processing techniques with Trimble GNSS technology.
+ How long does it take until I get my results?
It depends on the project length, but for standard operations (approximately 10 – 15min), the results can be obtained in about 5 minutes via a download link.
+ Do I need to know exact coordinates from the provided base station?
No! Users can make use of the RTX CenterPoint Technology and survey in the local base station. The only condition is that the antenna is supported by RTX CenterPoint and the time span is long enough (30 – 60min). A list of supported antennas can be found here.
+ What happens if I don’t upload a PhotoID file or if I don’t have the Web App create it for me?
The Web App will process the trajectory at 1Hz frequency and provide a generic ASCII file and the binary Applanix SBET.
+ Can ApplanixPPK also process inertial data?
No, ApplanixPPK supports only GNSS processing.
+ What Satellite Navigation Systems are supported by ApplanixPPK?
All known navigation systems are supported (e.g. GPS, GLONASS, GALILEO, BEIDOU, QZSS) as long as the provided Rinex Rover and Rinex Base files contain the according observations.
+ What is the benefit of PPK over RTK (RTK vs. PPK)?
RTK requires a real-time link via receiver/transmitter and is subject to interruptions which will reduce the final position precision. It also adds hardware needed in the field and one the drone. PPK does not have such limitations. RTK integrates the corrections only in forward mode while PPK runs backward processing to get a better picture of GNSS errors to create a smoothed solution. This solution is of higher precision and more robust.
+ How does PPK work?
PPK (post-processed kinematic) is an alternative approach to RTK (real-time kinematic). As the name says, PPK is not happening in real-time, but later, in post-processing mode. PPK merges the rover onboard GNSS data with base station data (collected at same time) and geotag the drone images. Doing this in post-processing mode provides more flexibility and better accuracy. Compared to RTK no real-time link between base station and drone is required, hence less infrastructure is needed in field. Due to the nature of receiving more accurate results from PPK, fewer GCP’s (ground control points) are required in field, which is a cost saving factor. In addition, PPK may also serve as backup for RTK in case of something goes wrong in real-time.
+ What is SmartBase processing mode?
SmartBase will utilize free available base stations world-wide to process a precise GNSS trajectory. The user does not need to provide a base station. However, there are regions in the world that are well covered and others that are less covered (sparse). We recommend the user to pre-check the coverage by using our SmartBase Cloud App. The user can proceed with SmartBase processing if the mission area is well covered by CORS, otherwise the user may need to load his own base station for single base processing.
