NGTR RFI Attachment 1 – DRAFT NGTR Performance Requirements

Introduction The Next Generation Tactical Radio (NGTR) is a Software Defined Radio (SDR) system intended to replace the AN/ARC-210 family of radios across multiple platforms. The NGTR shall provide expanded frequency coverage, increased waveform capability, improved size/weight/power performance, and enhanced security features while maintaining backward compatibility with existing aircraft and support equipment.
