Abstract

Real time sharing of aircraft data is an objective of connected aircraft strategies. With growing availability of high speed communication links (broadband/satellite), real time sharing of the aircraft data is enabled. Although efficient, current communication links suffer from challenges such as limited coverage area and unavailability of communication link. Further, the increasing demand for bandwidth in today's aircraft is a big challenge. The proposed solution utilizes the bandwidth of existing weather radar in the aircraft. The weather radar is configured to act as a communication device to allow aircraft to aircraft data communication.

ABSTRACT

Real time sharing of aircraft data is an objective of connected aircraft strategies. With

growing availability of high speed communication links (broadband/satellite), real time

sharing of the aircraft data is enabled. Although efficient, current communication links

suffer from challenges such as limited coverage area and unavailability of communication

link. Further, the increasing demand for bandwidth in today’s aircraft is a big challenge.

The proposed solution utilizes the bandwidth of existing weather radar in the aircraft. The

weather radar is configured to act as a communication device to allow aircraft to aircraft

data communication.

1. INTRODUCTION

Sharing of real time flight data between aircrafts requires connectivity links with high

bandwidth. Several satellite based connectivity links are being introduced to address the

high bandwidth requirement. Several factors such as data speed, cost, reliability of

communication link, and coverage area are considered while selecting the

communication link to be used. In current systems, flight data is shared between aircrafts

using ground systems due to the high bandwidth requirements. To address the high

bandwidth requirement, there is a need for augmenting the existing connectivity links. The

proposed solution provides a communication link via weather radars which are configured

to act as a communication devices.

2. PROPOSED SOLUTION OF THE PROBLEM

Unlike existing solutions which use satellite or broadband based communication links to

support high speed data communication, the proposed solution utilizes existing weather

radar as a communication device. The weather radar on board aircraft has a high

2

bandwidth. The radar is utilized as an X band radio for communication between

connected aircrafts. The radar is used for transferring flight related data (both high speed

as well as low speed) and weather related data. Various aircrafts can be connected to

utilize the bandwidth of the weather radar for data (e.g., Weather or Flight data) to be

shared among various aircrafts. As the weather radar is already present on aircrafts, there

is no requirement in terms of additional hardware, devices or equipments to meet the data

communication needs of the connected aircrafts.

Figure 1 shows an exemplary embodiment of two radars, radar 1 and radar 2 in

communication with each other. The radar 1 is the weather radar of aircraft 1 and radar

2 is the weather radar of aircraft 2. The transmitter and receiver sections are existing

radar components which are used for transmission and reception of data. Each radar is
