DESCRIPTION
Enabling smarter sensors onboard UAV payloads >>>Watch the replay: http://ecast.opensystemsmedia.com/410 Payloads onboard Unmanned Aerial Vehicles (UAVs) are enabling out more and more of the U.S. military's Intelligence, Surveillance, and Reconnaissance (ISR) missions. The ISR sensors in the payloads provide critical real-time imagery and intelligence, but often weak radio links force a compromise and distribution of that data. As a result UAV payload designers are packing more and more processing capability behind the sensor, enabling more data filtering at that level so only the most important information gets to the commanders in the field, cutting down on those communication bottlenecks. This e-cast of industry experts will cover how embedded hardware and software designers are tackling this challenge.

Baseline Capabilities for UASData Distribution Platform
• Open standards based– Commonality and interoperability
• True peer-to-peer architecture– No single point of failure or vulnerability
• Portable to any communication media– RF, optical links, high-speed interconnects
• Available for heterogeneous environments– Embedded, low-power, small foot-print, RTOS, ARINC 653– Mainstream OS’s (Windows, Linux) and CPUs (Intel)
• Certifiable component (DO-178C)– Integration of UAVs into civil airspace

Communications “Matrix of Pain”
• Multiple traffic types:– Sensor data streams– Command and control data– Status, intelligence, mission, supervisory data
• Different traffic requirements for each type:– Response time, priority, reliability, volume– Stealth operations
• Challenging communications channel:– Large latency, low throughput– Lossy– Varying availability– Asymmetric bandwidth (downlink vs uplink)
