The solution based on Mobile Phone (MP) sensors only (Pressure sensor, Gravity sensor and the GPS module).

The sensor fusion concept can be applied on all the following domains:◦ Automotive◦ Aviation◦ Shipping◦ Drones

For this Weekathon trial, we have focused on applying the concept on a aviation domain. Specially for the General Aviation and the light sport aircrafts categories.

Position

• The typical TCAS system is based on:1. Transmitting signal and measuring the

round trip time (RADAR). 2. Decoding the Aircraft Transponder signals.

Resolution Advisories

TrafficAdvisories

• When a TA is issued: Pilots are instructed to initiate a visual search for the traffic causing the TA. If the traffic is visually acquired, pilots are instructed to maintain visual separation from the traffic.

• When an RA is issued, pilots are expected to respond immediately to the RA, unless doing so would jeopardize the safe operation of the flight.

1. Situational and air traffic awareness.2. Warning and advisory system.3. Mandatory for the Airline category

aircrafts4. Cost between $25,000-$150,0005. Not affordable for most of the General

Aviation (GA) and light sport Category aircrafts.

Implemented on a Mobile Phone. Utilizing the common sensors comprised in the

Mobile Phone, including the GPS module. The Data exchange based on :

◦Cloud service (Cellular 3G/4G).◦Ad-Hoc Communication System. ◦Integration of the two above.

Ad-Hoc Based Communication

Sensor Data exchange such as:speed.Altitude.PositionCourse User Data Exchange such as:Call signAircraft Type.Traffic Frequency Channel .

All Aircraft in Traffic clearance zone

Cloud Server:• Holds database of all Aircrafts in the zone.• Call sign, Aircraft type, Altitude, Position, Course… • Sends all the traffic info inside the clearance zone.• In future - “Waze Like” application for aviation traffic.

Server to Aircraft Data:

Mobile Phone application.◦ Affordable ◦ Available to everyone.

No need of Transponders or any other equipment.◦ Most of LSA- Light Sport Aircraft are not equipped with

Transponders. 360 degrees intruder alert and advisory. Potentially “Waze Like” application for aviation

domain.

Transponder

Yesterday, after 3 day of development only, we have visited at the customer’s site - Hertzeliya Airfield (LLHZ), the center of the General Aviation activity in Israel.

Lets see the results:
