ASAR, a system for crisis, search and rescue coordination

From first responders, for first responders.

As head of the national 112 centre I saw the same problem in every crisis: the first questions are where do we start, who do we call and do we have an SOP, while time is running. ASAR gives the answers in minutes: prediction, a plan, drones and teams on one screen, with AI that suggests the next step. Everything that is decided stays in the system.

For 112 centres, civil protection, mountain rescue, MRCC, fire services, police and armed forces.

The SkyFlight app was part of the unmanned aircraft operations training programme of the Civil Protection Directorate, the Maritime Rescue Coordination Centre (MRCC) and the Croatian Armed Forces, Jastrebarsko, 31 March to 4 April 2025. Read the announcement

When a crisis hits, you have five minutes.

Not to act, but to decide where to start. Everything after that depends on that decision.

01

“Where do we start?”

The most important question with no fast answer. While the coordinator estimates the area by hand, every minute lowers the odds.

02

“Bravo, Charlie, Alpha…”

Coordinates are spelled out over the phone, forms are filled in by hand, and information reaches the emergency services late.

03

Every team on its own channel

Helicopters, boats, ground teams, drones and firefighters on different systems. Nobody sees the whole operation.

04

Data entered wrong

A coordinate copied from a phone call, a time written from memory. One mistake on a form sends teams to the wrong place, and later nobody can reconstruct it.

ASAR

Ten modules. One screen for the coordinator.

Each module covers prediction, planning and coordination for its type of crisis. All of them share satellite imagery, AI reports, the audit log and multi-organisation work on the same incident.

AIR

Aircraft crash

Monte Carlo prediction of the crash site, RCC form, NOTAM zone, coordination with civil and military aviation authorities.

SEA

Missing at sea

Leeway drift with Copernicus sea currents and wind. Position prediction after 1, 3, 6 and 12 hours, MRCC coordination.

LAND

Missing persons on land

Koester statistics, 50/75/95 % probability zones, sectors, tasks and GPS tracking of teams.

FLOOD

Floods

Levee breach simulation, barrier placement, evacuation routes and spread prediction.

FIRE

Wildfires

NASA FIRMS hot spots, spread prediction, firebreaks and satellite overview of the burnt area.

CBRN

Chemical, bio, radiological

ATP-45 contamination plume prediction, ERG database with 125 substances, 12, 24 and 48 hour projection.

EQ

Earthquakes

EMSC monitoring, damage zones by magnitude, satellite before-and-after view.

UAV

Drones

Fleet, pilots and altitudes in real time. One ACO manages all aircraft.

NOTAM

Airspace and NOTAM

Airspace reservation without guessing which request to send. The module drafts the correct request to air traffic control. Also available on its own.

BEACON

COSPAS-SARSAT beacon

Processing of 406 MHz beacon signals: HEX ID, registration data and position as the starting point of the search.

You buy only the modules you need and scale to the real needs of your organisation. ASAR is available in the cloud or as an on-premise installation on your own infrastructure, with an SLA maintenance agreement. Everything about ASAR at asar.skyflight.hr

Shared by all modules

Incident handover

To another institution with its full history, in one click.

Coordinator change

After a shift with no loss of context: everything that was decided, and why, stays in the system.

Lessons learned and final report

Built from the operation data, with no retyping afterwards.

Every entry logged

With time and author, so a wrong entry does not disappear: it is corrected and visible.

Satellite imagery without waiting

Sentinel-1 and Sentinel-2, NASA FIRMS and Copernicus in the system. ASAR drafts the ERCC request for imagery of the affected area for you, in one click.

Optional AI assistance

Add your own API key and switch on AI mode when you need it. AI suggests next steps, and reports and outgoing replies follow your standard text protocol, so reporting is faster and consistent.

Drone platform

One person coordinates every aircraft.

We built the platform inside the emergency services, for the emergency services. Several organisations fly in the same zone with assigned sectors and altitudes, and the coordinator sees every pilot on the map. It has been in production for more than two years.

  • Sectors and altitudes in real time: the ACO assigns, pilots see.
  • Digital licences, insurance and aircraft documents with QR verification.
  • Airspace reservation and notification to air traffic control for TRA/TSA operations.
  • Several organisations in the same zone, one situation picture, KML export.
  • Quizzes based on EU regulations and SOP distribution to pilots.

Platform

ASAR is the main platform for data collection and coordination.

Around ASAR are the tools that bring data in from the field and send tasks back to the people who carry them out: the Drone platform, ASAR Mobile, the TAK server and the media server. Each part works on its own, and everything flows onto the coordinator’s single screen.

Core

ASAR platform

Prediction, planning and coordination of every crisis. Ten modules, satellite imagery, AI reports, audit log and multi-organisation work on the same incident.

Drone platform

Web for the aircraft coordinator (ACO) and a mobile app for pilots. Sectors, altitudes, licences and fleet.

ASAR Mobile

App for field teams: task, sector, navigation, photos and status back to the coordinator. Compatible with ATAK-CIV.

TAK server

The bridge between the field and the centre. Both mobile apps talk to the TAK server, and it talks to ASAR. The server already runs on our infrastructure.

Media server

Live video from drones and the field to the coordinator and superiors.

BECIS In development

Bilateral cooperation without digging through drawers: a register of agreements, the obligations they carry and step-by-step SOPs, digital and semi-automated. What CECIS is for the EU mechanism, BECIS is for bilateral agreements.

The system is delivered tailored to the organisation: the selected modules, cloud or on-premise installation, setup, training for coordinators and field teams, and maintenance under an SLA agreement. Details are agreed at the demo.

In the field

Two mobile apps. One map in the centre.

The pilot and the field team each have their own app. Both work with the TAK server, so the coordinator in ASAR sees everything on the same map.

SkyFlight for pilots

SkyFlight for pilots

Assigned sector and altitude, flight zone, documents and licences, weather and flight log. Available on Google Play.

ASAR Mobile for field teams

Task, sector and navigation in the app. GPS tracking, photos and status in real time. Compatible with ATAK-CIV. Distributed to organisations together with the system.

Who is behind ASAR

Built by a coordinator who knows what every minute is worth.

I am Kristjan Vuković. I have been building software since 2002, when I designed, built and for years maintained the Zagreb Police Administration website as its webmaster. ASAR and the Drone platform came out of the job, not out of a business plan. As SAR Mission Coordinator and remote pilot operations coordinator I led search operations after aircraft crashes, managing drones, teams and search sectors. The same question at the start every time, and every time the answer put together by hand. This is the system I wanted to have in the centre.

Operational experience

  • More than five years as head of the national 112 centre.
  • SAR Mission Coordinator and remote pilot operations coordinator on real operations.
  • Coordination of drones from several institutions on one interface in large search operations.
  • Lecturer at the unmanned aircraft operations training of the Civil Protection Directorate, 2025.

Systems and standards

  • National coordinator for CECIS, the EU emergency communication and information system.
  • Administrator of the SRUUK system.
  • Member of the EU COLLARIS and COLLARIS 2 networks for unmanned aircraft systems in civil protection.
  • Member of HZN/TC 583 Unmanned aircraft systems, Croatian Standards Institute (mirror committee of CEN/TC 471).

Commissions

  • Chair of the Commission for approval of the wildfire video detection and surveillance system, Zadar, Šibenik-Knin, Split-Dalmatia and Dubrovnik-Neretva counties, 2021 to 2025.
  • Deputy member of the Commission for monitoring and amending standard operating procedures under the national wildfire activity programme, with representatives of the Ministry of Defence, the Croatian Firefighting Association, the Ministry of the Interior, Croatia Control and the Civil Aviation Agency, since 2024.
