High Jamming Tolerance

- Essential

for operation in a tactical battlefield

environment. TruNav

tm

is designed with

a number of adaptable parameters to

mitigate jamming. It includes an ultra

tightly coupled GPS/IMU integration,

which allows GPS tracking at higher

(10-15 dB) J/S than with conventional

tracking loops, with software only.

Direct Y-Code Acquisition

-

Direct Y-code acquisition is essential

in a high jamming environment.

The IEC receiver portion of TruNav

design implements a time hold

mode to retain initialization data and

propagate GPS time, the actual time

of projectile.

Ultra Fast Acquisition

-

This is particularly important for short

missions since the missile is usually

not tracking satellites prior to firing.

In addition, fast acquisition means

a longer control period during flight

time and lower (up-range) jammer

levels for initial IMU calibration.

DDC

- <4 Sec TTFF @ 55 dB J/S.

Newly patented Direct Deep Coupling

(DDC) is L-3's latest technology

that uses our proven deep coupling

algorithms for initial GPS acquisition

providing ultra fast TTFF in high

jamming (at J/S levels most receivers

are not able to track).
