Propeller PPK FAQs

Learn more about Propeller’s PPK Solution—the next evolution in drone surveying

How accurate is the Propeller PPK solution?

Propeller’s GPS experts have worked alongside select drone manufacturers to ensure that their L1/L2 GNSS receivers work seamlessly with Propeller’s own developed technology to bring easy, affordable, and highly accurate maps to the wider commercial drone industry. Propeller uses Agisoft Metashape as part of our imagery pipeline to realise survey-grade accuracy

If you are using one of our recommended drones and are following best practices, the Propeller PPK solution can deliver survey-grade accuracy to within 1/10ft (3cm).

What does the Propeller PPK surveying workflow involve?

In terms of operational workflows it couldn’t get any simpler.

  1. Plan out your drone’s flight on the flight planning app
  2. Find a safe, open area on your site to launch the drone from
  3. Set up an AeroPoint on the ground nearby you and turn it on
  4. Hit Go on your drone flight

Once the drone finishes its flight and automatically returns to your location, upload your data to Propeller and let us do the processing for you.

There’s no need to download any software. No need to tweak or preprocess imagery or site data. In 24 hours, your 3D site survey is rendered with survey-grade accuracy and you can start measuring and managing your site and your assets immediately.

Does Propeller recommend the PPK or RTK solution?

Propeller recommends PPK over RTK solutions. Because the RTK drone needs to maintain a connection to the base station the whole time it is taking data, any signal loss can have big repercussions in your dataset. Simple maneuvers as flying behind a building can disrupt the signal. Due to this possibility of inconsistency, we recommend PPK workflows over their RTK counterparts.

That said, Propeller does offer support for RTK workflows with high accuracy geotags. Check with your sales representative or in touch here to see if your existing hardware is compatible.

Do I still need to use 10 AeroPoints with Propeller PPK?

If you’re using Propeller PPK, are flying a site up to 150 acres (60 hectares), and are following our best practice guidelines then you can achieve 1/10ft (3cm) accuracy using only one AeroPoint. However, in most cases we recommend that customers try to use at least three AeroPoints to ensure they have the best possible chance of achieving the desired accuracy.

You can find more detailed information on how many AeroPoints you need to get accurate results here.

How do I get my Propeller PPK set up?
