Reduces or eliminates the need for ground control points!

Why would you want a Phantom 4 Pro with PPK over buying a Phantom 4 RTK? Well we can think of at least four very good reasons:

(1) You don’t need to buy a whole new drone. We can retrofit our PPK system to your existing Phantom 4 Pro fleet.

(2) You can still use your favourite mapping apps. We won’t force you to use DJI proprietary mission planning software.

(3) PPK is so much better than RTK. Google it and read the facts for yourself. No complicated radio communications, no worries about WiFi interference. And PPK is more accurate too!

(4) PPK can be used over much larger mapping areas without degrading precision and without worrying about signal loss or reflections.

Serious professional mapping with UAVs demands high precision and accuracy. The BAAM Tech PPK system, designed and manufactured in the USA, can be retrofitted to your DJI Phantom 4 Pro to reduce or even eliminate the need for ground control points.

If you’re not familiar with PPK (Post Processed Kinematic), it’s a high accuracy GPS system that simplifies your workflow because all of the precision work is done after the flight, using a simple post-processing system.

Mapping professionals have much more flexibility over where the drone is used, how they lay out flight grids and the area which can be mapped in a single mission using PPK than with any other corrections system currently available.

It’s also much easier and faster (up to 75% faster) to get accurate survey data using PPK over traditional ground control points (GCPs) or Aeropoints, so your time can be more productively and efficiently used.

High Accuracy Multi-Constellation GPS

While RTK integration options typically use only L1 GNSS data, the BAAM Tech PPK system for the DJI Phantom 4 Pro uses GPS L1/L2 and GLONASS G1/G2 GPS data, supplemented by BeiDou B1/B2, Galileo E1/E5B and SBAS constellations.

The use of multiple satellite positioning systems greatly increases the GPS signal quality to provide the most accurate UAV positioning data, especially in “noisy” urban environments.

Accurate Geo-Tagged Images

The BAAM Tech PPK system has overcome one of the biggest limitations of integrating RTK/PPK into the Phantom 4 Pro by connecting directly to the shutter of the DJI camera and calibrating to ensure the geotagging is of the highest quality.

Each PPK system includes BAAM Tech’s easy-to-use post-processing software that will make the required corrections to image positions by calculating the actual location of the UAV when each image was captured, using either a local base or a CORS base station. The corrected data is used to update the EXIF data with precise geo-locations and you can process the imagery as you do now.

One System for Ground and Air

Because the BAAM Tech PPK system comes with an easily removable module, the same unit can be used as a ground rover to collect GPS data for precision ground control points, before being slid back into the aircraft for PPK precision mapping flights.

This removable modular technology significantly decreases the cost of precision surveying by allowing the same system to do both air and ground position corrections. A base station version is also available for base-rover configurations.

Complete PPK Survey System

We recommend using the DJI Phantom 4 Pro PPK module in conjunction with the BAAM Tech PPK Base and Rover system to facilitate easy placement of ground control points (you may still need 3-4 for absolute precision) and PPK flight within the same simple workflow and post-processing software.
