The GPNVG night vision is the pinnacle of night vision technology. They are the most advanced night vision goggles on the market today.

GPNVG stands for Ground Panoramic Night Vision Goggle. They are the first set of quad tube night vision goggles and provide the user with a wider field of view.

These use a total of four tubes compared to most modern night vision goggle setups that have only two.

The GPNVG is a helmet-mounted night vision device with a wide 97-degree horizontal field of view that allows for observation and/or target identification under adverse conditions and is ruggedized for ground applications.

One of the biggest innO you know ground panoramic night vision goggleovations in night vision technology with the Ground Panoramic Night Vision Goggle (GPNVG).  The purpose of the GPNVG is to provide the operator more information under goggles, allowing them to more quickly move through the OODA Loop (Observe, Orient, Decide, Act). The most striking feature of the GPNVG is the presence of four separate image intensifier tubes with four separate objective lenses arrayed in a panoramic orientation. The center two lenses point forward like traditional dual-tube goggles, giving the operator more depth perception, while two more tubes point slightly outward from the center to increase peripheral view. The two tubes on the right and the two on the left are spliced at the eyepieces. The operator sees the two center tubes somewhat overlapping the two outer tubes to produce an unprecedented 97° FOV.  The two right and two left tubes are housed in merged assemblies and are hung from a bridge similar to ANVIS goggles, giving operators transverse interpuplliary adjustment. They can also be easily removed and operated as independent handheld viewers.

System adjustment and placement is key in providing the best image to the operator. One of the main adjustments for focus in a night vision goggle is the diopter. Diopter focus adjustment is traditionally achieved by rotating a diopter focus ring. This adjusts focus of the goggle as it is in relation to the individual wearer’s eye(s). The challenge presented by the panoramic lens assembly of the GPNVG is that the rear lenses are “fused” together, almost like a prism. This is what gives the operator the overlapping images from the forward and angled tubes. But, it also keeps the goggles from being able to have diopter rings for focus. The GPNVG comes standard with a -0.50 dioter insert, optimized for the 95th percentile of users, however diopter adjustments can be accomplished with interchangeable diopter windows that stand off the lens.

The GPNVG utilizes mil-spec Gen3 Unfilmed White Phosphor 18mm MX-10160 image intensifier tubes. These tubes are good for maintenance because they use L3Harris' solder-free replaceable tube design. This is a very welcome feature since the modular L3 tubes do not require a whole operation to replace. Some quick work with common tools, and the tube replacement is done. In fact, the entire goggle has been designed with maintenance in mind. One of the biggest issues with NVG’s (and just about any highly technical device) is maintenance of damaged/non-functioning equipment. This is often a lengthy process that requires a unit to be without equipment for a while because devices require specialty tools and facilities for repair. The GPNVGs have a totally modular chassis with a fully serviceable bridge.

The advantages of the increased, panoramic field of view offered by the GPNVGs cannot be overstated. Not only do they have obvious benefits for assaulters, but they offer critical situational awareness to vehicle and watercraft operators, increasing safety and reaction/response time. When used by multiple operators working in a team, the GPNVGs have a multiplicative effect, offering greatly enhanced security with interlocked fields of fire and observation, reducing operator fatigue and “giving up” dead space when scanning surroundings.
