Variable-zoom telescopic sights in the low magnification range (1–4×, 1–6×, 1–8×, or even 1–10×) are known as low-power variable optics or LPVOs. These telescopic sights are often equipped with built-in reticle illumination and can be dialed down to 1× magnification.

The primary sensor of the GlobalEye is its Erieye ER airborne early warning (AEW) radar. Weighing approximately 1 tonne, it is mounted atop the twinjet's fuselage. [7] Saab has cited up to 450 km (216 nm) range for the AEW radar system when flown at an operating altitude of 30,000 ft, [14] and 550 km at 35,000 ft. [15] In comparison with earlier versions of the Erieye radar, Saab claims it has ...
The scope body is sealed and filled with nitrogen, which prevents fogging of optics and was designed to function within a -50 °C to 50 °C temperature range. For zeroing the telescopic sight the reticle can be adjusted by manipulating the elevation and windage turrets in 5 centimetres (2.0 in) at 100 metres (109 yd) (0.5 mil or 1.72 MOA ...
