- 16. 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 © Newtec Cy nv – All Rights Reserved. Newtec Proprietary Information 16
- 17. Airborne ISR Best Practice Experience through Practice 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 © Newtec Cy nv – All Rights Reserved.
