How does erieye stack up to the new globaeye system?
Globaleye brings a significant improvement in range while maintaining the same power and size requirements. For this, SAAB switched to Gallium Nitride (GaN) based T/R modules, whereas legacy Erieye uses Gallium Arsenide (GaA) modules. GaNs can squeeze out upwards of 40% more raw EM power for the same power input vs GaA. Beyond this, the Globaleye probably has greater on station time and also most definitely would carry a superior EW/ECM suite alongside ELINT sensors. Another big talking point for it was its dedicated SSR, the Seaspray 7300E(i could be wrong though about the model- i am talking from memory). Allowing it to provide a more comprehensive view of the ground, could also be used for maritime patrol and also recce, through its SAR modes. However, you can achieve some form of ground view using the air search antenna too. For example, the Legacy Erieye can track jetski sized targets on the sea.
