TOWER vs. InSAR monitoring services.
InSAR services measure movement very well. TOWER is built for airport teams and goes one step further: it shows where to check first.
| Free regional data service (e.g. EGMS) | InSAR monitoring services | TOWER | |
|---|---|---|---|
| Type | Free European ground motion data | Monitoring services for ground and assets | Airport SaaS |
| Main strength | Ground motion across Europe | Precise ground and structure movement | Ground movement, temperature and aircraft for one airport |
| Updates | About once a year | From every few days to set schedules | Every 12 to 15 days |
| Results in | Map explorer and downloads | Web GIS platforms and viewers | Airport map and AI reports |
| Where to check first | Users analyse the data | Usually not stated | AI suggests priority areas |
| On-site equipment | None | Varies by project | None |

When to use what
TOWER works well alongside other data.
Use EGMS
For a free, regional first look at ground motion across Europe.
Use InSAR services
For detailed engineering studies of specific structures.
Use TOWER
For regular, airport-wide screening and a priority list for field teams.
FAQ
Frequently asked questions
Is TOWER an InSAR provider?
TOWER uses InSAR as one input. It is an airport SaaS that combines ground movement with temperature and aircraft detection and uses AI to suggest where to check first.
Can TOWER use EGMS or other data?
TOWER works with data from 10 satellite missions, including free Sentinel-1 data, which is also the basis of EGMS.

Let’s run a PoC together.
We hope to start with public satellite data at your airport: no equipment, a screening report first, then field checks with your team.
