Airborne ISR Best Practice Experience through Practice
Use Case ISR

•  Challenges
–  Small Airframes
–  High data rate requirement – aircraft are data producers, not data
consumers
–  Small amount of rack space and weight available to accommodate
electronics and antenna (SWAP extremely limited)
–  Rapid deployment timeline compressed amount of time available for
development, integration, and testing
–  Certification requirements
•  Certification for testing in the Continental US
•  Certification for operational use

16

Use Case ISR

•  Functional Requirements
–  System must be able to support data rates of at least 10 Mbps from the aircraft
to the ground via satellite
–  Multiple aircraft must be able to be supported simultaneously
–  System must be able to support data rates of at least 2 Mbps from the ground
back to the aircraft
–  All data interfaces must be compatible with Internet Protocol
–  All Intermediate Frequency (IF) interfaces must be commercial L-Band
–  External hardware (antenna, radome) must be able to be fitted on multiple
types of aircraft
–  Operator interface must be simple enough to be operated by personnel who are
not satellite experts

17

Use Case ISR

•  Demonstrated Performance & Results
–  During testing and operation, the system has been successfully operated on the
following spacecraft
•  Skynet 5A
•  Skynet 5C
•  Skynet 4E
•  XTAR-EUR
•  XTAR-LANT
–  Data rates from the aircraft to the ground terminal in excess of 10 Mbps have been
demonstrated on each satellite
–  Data rates from the ground terminal to the aircraft have been demonstrated on each
satellite
–  Use of Adaptive Coding & Modulation (ACM) on Newtec EL470 modems provides,
on average a 30-50% increase in usable data rate by converting extra link margin to
usable data rate
–  The system is currently operational, supporting multiple aircraft

Border Patrol:
•  Convair 580
•  Configuration for BLoS over X-band
•  Point-to-Point
•  16APSK 5 Mbaud
•  Up to 10 Mbps Euro Hawk (ISR):
•  Newtec Optimization SW hub & UAV
•  Resolve Delay & Increase Efficiency
•  Newtec Cross-Layer-Optimization
•  QoS
•  Priority
ISR: •  Acceleration
•  C-12 •  Compression
•  Inclined Orbit Satellite
•  Configuration for BLoS over X-band
•  Point-to-Point
•  Average 10 Mbps
•  Up to 16 Mbps And Many More....

19

Airborne ISR Conclusion

•  Airborne ISR faces many challenges
–  from increased data rates
–  To operational and practical issues when airborne

•  Difficult is fun… the recipe to success:
–  Efficient throughput
–  Optimal availability
–  Improvements beyond DVB-S2 (S2 Extensions)
–  Not your typical TDMA
–  Experience through practice
