What is Joint Tactical Radio System (JTRS)?
The transformational efforts of DoD’s architecture depends on
the information infrastructure called the Global Information Grid
(GIG). Without a capability like JTRS, the GIG’s transformational
networking would halt at the command center level, unable to
extend to the actual mobile warfighters. Figure 1 illustrates JTRS
Increment 1 Network Architecture Overview. JTRS is critical to
serving as the last tactical mile connecting the warfighter on
the ground into the networking capabilities that are delivered
through the GIG. Under the newly revised requirements, budget, and
schedule established for the program, JTRS will provide the
mobile, ad hoc networking capability that is essential to
realizing DoD’s transformational goals for the warfighter.
What is a Waveform?
A waveform is the entire set of radio and/or communications
functions that occur from the user input to the radio frequency
output and vice versa. JTRS waveform implementation consists of a
Waveform Application Code, Radio Set Devices and Radio System
Applications. Originally, there were 32 JTRS waveforms which have
since been reduced to the following 9.
•Wideband Networking Waveform (WNW)
•Soldier Radio Waveform (SRW)
•Joint Airborne Networking–Tactical Edge (JAN-TE)
•Mobile User Objective System (MUOS)
•SINCGARS
•Link-16
•EPLRS
•High Frequency (HF)
•UHF SATCOM
What is a Form Factor?
A form factor is the linear dimensions and configuration of a
device, as distinguished from other measures of size. The initial
26 form factors were reduced to the following 13.
•Ground Mobile Radio (GMR)
•Multifunctional Information Distribution System for JTRS (MIDS-J)
•Manpack
•Handheld
•Airborne, Maritime and Fixed Site Small Airborne(AMF-SA)
•AMF-MF (Maritime/Fixed Site)
•Small Form Factor A&H (for Intelligent Munitions Systems and
Unattended
Ground Sensors in the Future Combat System)
•SFF B, C and I (for Ground Soldier Systems)
•SFF D (for Aerial Systems)
•SFF J (for Networked Missile Launcher System in FCS)
