The Watson GGC-E101 provides attitude and GPS-based heading reference data. Three rate gyros, three accelerometers along with a GPS receiver and up to 65 meters of cabling are all housed within a rugged, water-resistant, portable case. The GGC was designed with portability and a quick set-up in mind. The cabling is stowed in the cover and the GPS antennas easily fold together and drop into the base for storage. This sensor system is a good choice for applications that require accurate alignment to a particular heading. Additional data provided by the GGC include: roll, pitch, and yaw rate, X, Y, and Z accelerations. Leveled accelerometer outputs are also available along with attitude data.
The GGC is intended to be transportable, so durability is important. The sensors in the GGC can survive shocks of up to 500g, and vibrations up to 10g. The entire sensor package fits inside a housing the size of a suitcase. This design allows the GGC to be easily transported and quickly set up in a new location.
The GGC-E101 is used in the energy industry for the orientation and positioning of oil rigs. This sensor system is also useful for the alignment of satellite antennas, alignment and leveling of industrial equipment, and any other application where a portable system with precise orientation is needed.
