A drone detection system with its own maps and remote updates for a fleet of more than 500 units.
ASDT Corporation develops drone detection and tracking systems. SendeScope combines physical detectors (GPS and sector radio frequency) with a tablet application that centralises detections in real time, deployed in field kits used at institutional events, large gatherings and defence settings. ASDT needed full control of its product: publishing versions, managing the maps and updating the fleet without depending on third parties.

The challenge
The legacy system depended on an external team. No version could be published without their certificate, there was no control over the maps or the application versions, and updating the tablets required travelling to each installation.
On top of this came failures in the environment where they can least be tolerated: crashes during tracking, detections lost when changing location and memory leaks in long sessions. Control had to be recovered and quality raised at the same time.
These cases work on hostile ground with no coverage, and a commercial map service needs a connection to serve every tile. That is why the maps live on the device and come from a server of our own. But that was not what made the biggest difference: rebuilding the whole interface was, because that is where the inherited system weighed on them daily.
Our approach
We integrated the application signing into the build flow, which removed the dependency on the external certificate. ASDT builds, signs, publishes and deploys new versions autonomously, on container infrastructure ready for production.
A server of our own generates maps on demand from an administration panel: four styles, coverage for 13 countries that extends without code changes, automatic thumbnails and access logs. It is optimised to serve multi-gigabyte files to the tablets.
A version server delivers the application to the tablets through authenticated downloads. When a version tag is created, the pipeline builds, numbers and publishes the version. A new version reaches the whole fleet in under a minute.
We renewed the map system with offline rendering, visual downloads and automatic retries. We distinguished radio-frequency detections (directional cones) from serial-number detections (model icon), added in-app updates and four languages, and resolved the crashes, memory leaks and lost detections.

The impact
Where each installation once had to be visited, a new version now reaches the more than 500 units remotely, with a record of the version installed on each one.
ASDT builds, signs, publishes and deploys on its own. Maps and updates run on its own controlled, production-ready infrastructure.
Crashes, memory leaks and lost detections were resolved. The system is proven at institutional events, large gatherings and defence settings, on terrain with no coverage.
New countries and map styles without code changes, and an architecture ready for the next version of the communication protocol.
The relationship is still open. We support ASDT through the evolution of the product and the versions that reach the fleet.
