The BAAM Tech™ PPK System

What is a PPK system?

PPK is a high accuracy GPS like RTK that does not need a radio link between the aerial mapping drone and the base and does the corrections post collection. PPK systems offers many advantages to drones 1. it eliminates the need for ground control points. Greatly reducing the field work required for each mission. 2. It cleans up the data reducing many of the point errors seen on common areas in point clouds.

The BAAM Tech™ PPK system offers aerial mapping drones a unique way to collect data. Where most other systems require $40k GPS equipment to collect check shots and do ground surveys, the BAAM Tech™ system is plug and play with the system allowing you to plug the PPK GPS into our ground-based rover to do ground surveys, then plug it into the aircraft and fly. All with a single PPK system.

The PPK System Features

BAAM Tech™ has set out to create the perfect PPK System



While most other system only use L1, or L1/L2 the BAAM Tech PPK System uses GPS L1/L2 and GLONASS G1/G2, BeiDou B1/B2, Galileo E1/E5b and SBAS constellations in its base package and does not charge for upgrades for the constellations. This allows for extremely accurate data with most flights having the GPS locked for the entire flight. This also allows for a very fast startup time within a minute or less. BAAM Tech’s PPK system outpaces traditional GPS equipment for aerial mapping drones in accuracy and deployment.

High Accuracy PPK

High Accuracy PPK


When most other PPK systems only use L1 or just L1/L2 the BAAM Tech PPK system utilizes GPS L1/L2 and GLONASS G1/G2, BeiDou B1/B2, Galileo E1/E5b and SBAS constellations. The significantly increases the quality of the signal and allows for more accurate data especially in the noisy environments in drones.

Accurate Geo-tagging

Accurate Geo-tagging

The BAAM Tech PPK is directly connected to the shutter of the camera and is calibrated to ensure the geotags are of the highest quality.

Each system is provided with BAAM Techs easy to use post processing software that will make the corrections between the base and the Phantom and directly geotag the images.

Easily Remove GPS

Easily Remove GPS

The GPS system slides in and out of the aircraft allowing the GPS to slide into our ground rover to collect ground control, or check points then can slide back into the aircraft for the PPK flights. This significantly reduces the price of surveying, and allows 1 system for all of the field work.

We also offer a GPS base for corrections.

The Base

The Base

A base is needed to provide corrections to the aircraft’s GPS. The base is setup over a known point or the point is found post collection is a system like Opus. The Base can be any base or CORS station within 5 miles that is at least L1/L2 and GLONASS (ideally off of the same constellations) That is running a 1 second observation and can output a Rinex file.

The procedure:

  • Setup the base and start recording a 1 second observation.
  • Turn on the aircraft and take a picture of the calibration panel
  • Fly
  • Put all of the data into BAAM Tech’s Post Processing Software
  • The images are directly geotagged and can go directly into Pix4D or Equivalent
BAAM Tech’s PPK Software

BAAM Tech’s PPK Software

BAAM Tech PPK Software is included with every order, and updates are free to customers. The software inputs the Aircraft/Rover PPK file, and the Bases file and location then makes the corrections. That data is then Geotagged directly into the meta data of the image.

Through their years of experience operating drones, Baam Tech recognized the fixed wing drone solutions commercially available were not up to the task. BAAM.TECH has set out to create an aircraft that addresses all problems facing survey grade drones. READ MORE>
