Of course, there are other alternatives, such as adding antijam
capability to unprotected wideband systems.
The Topshield system provides antijam
immunity above 90dB using null steering to cancel multiple jammers and beam forming for concentrated satellite connection through Space Time Adaptive Processing.
For example, next-generation GPS satellites will include better inherent antijam
and enhanced civil capabilities.
(6) Improved antijam
features can counter jamming defenses.
Wayne, IN), achieves antijam
capability by hopping over 2,320 different frequencies in the 30- to 88-MHz region.
A nation's robust DCS operations reduce this threat with hardened satellite systems, antijam
components, kinetic attacks against ground jammers, frequency-hopping and spread-spectrum signals, on-orbit maneuvers to evade hostility, and rapid reconstitution of on-orbit systems.
(Fairfield, NJ), received a contract under the US Army's Advanced Concept Technology Program to develop a antijam
(AJ) antenna for retrofit on the handheld AN/PSN-11 Precision Lightweight GPS Receiver (PLGR), manufactured by Rockwell Collins (Cedar Rapids, IA).
This satellite is also the key to assured service because it provides high-capacity antijam
protection to a large group of users through laser communications.
ERI's GSD development expertise includes digital receivers, sensor-fusion processors; target augmentation for drones, expendables and UAVs; towed decoys; flight-line expert systems for fault isolation; and GPS Interference Suppression (antijam
With low-insertion loss switches in the feed network, we were able to switch from default mode main antenna to array antenna (antijam
mode) or vice versa.
Furthermore, the enemy can defeat IA by destroying signal jammers or boosting his own signal to negate the signal (antijam
Link 16 is what NATO calls its antijam
, secure data and voice system that incorporates waveforms and messages supported by Joint Tactical Information Distribution System (JTIDS) and Multifunctional Distribution System (MIDS) terminals.
