TruTrak

TM

for Projectiles has a number

of features necessary to survive and

operate in the dynamics of a projectile

environment.

Gun Hardening

TruTrak

TM

has been demonstrated to

survive 16-millisecond 15.500 G setback

and 5,000 G lateral (balloting) gun shock

loads.

Very Fast Direct

Y-Code Acquisition

TruTrak

TM

has been demonstrated to

perform Direct Y-code acquisition

within seconds of gunfire. The receiver

includes a time hold mode to retain the

initialization data and propagate

GPS time between the projectile

initialization station and gunfire as

well as oscillator compensation to

operate reliably even after 20 years in

storage.

High Jamming Tolerance

TruTrak

TM

is designed with a number

of adaptable parameters to mitigate

jamming. In addition to optimized

digital processing for acquisition and

tracking, it is capable of operating

tightly coupled to an external IMU,

which allows very narrow bandwidth

tracking to suppress jammers.
