GPSgeleide

GPSgeleide refers to guidance of a weapon or device using the Global Positioning System (GPS). In this approach, a predefined target location is loaded into the weapon’s guidance system, and GPS signals are used to determine the weapon’s position during flight so that corrective maneuvers steer it toward the target. The result is typically improved accuracy under various weather and lighting conditions.

A typical GPSgeleide system combines a GPS receiver with an inertial measurement unit (IMU) and a flight computer. The GPS provides absolute position data, while the IMU tracks motion and helps bridge short GPS gaps. The flight computer computes steering commands, which are delivered to control surfaces or propulsion to adjust the trajectory. Some systems also use terrain or velocity data for added guidance integrity. In many applications, the warhead is detonated near the target by a programmable fuze.

Applications and examples include air-dropped bombs and artillery projectiles that use GPS guidance to achieve precision in all-weather conditions. Notable examples are Joint Direct Attack Munitions (JDAM) and precision-guided artillery rounds like Excalibur or program-specific kits that convert unguided munitions into GPS-guided assets. GPSgeleide technologies are used by several military forces around the world and have influenced modern precision strike capabilities.

Limitations include dependence on satellite visibility and signal integrity. GPS signals can be jammed or spoofed, and in GPS-denied environments, guidance may rely on inertial navigation or alternative navigation methods for continuity. The technology has driven significant improvements in accuracy and mission effectiveness, but it remains subject to countermeasures and access controls.
