Electronic Test Fuze
Precision and Advanced
FUZE - ETF
What is ETF?
z Designed to support realistic gun-shock testing of
z Digital processor can command and control
subsystems under test in flight.
z ETF is a diagnostic suite of sensors including 3
axis magnetometer and single axis accelerometer
z ETF is an analog and digital signal multiplexer that
encodes data into a single stream used to
modulate an RF transmitter
z ETF is a gun hardened system with self contained
Electronic Test Fuze (ETF) designed to
support Guidance Integrated Fuze (GIF)
TM Support Housing
Control Panels that Rotate
Controlling the Spin Rate
and “throttling” the Drag
COTS Battery Module
GIF-Based GEU with
Advanced Anti-Jam and
Backup “Command Mode”
using PTS if GPS is Denied
4-Patch GPS Antenna System
• Simpler than Navy “Lift-GIF” yet more robust
in terms of Jamming and Reliability.
• ~$1K Less Expensive in Production
• Capable of a 15m to 20m CEP.
• Applicable to All Ammo Types.
• Meets or Exceeds PGK Inc 1/2/3 Requirements.
• Leverages All Previous Navy-GIF Developments
except the Roll Brake and Bearing Assemblies.
