Bell Helicopter Inaugurates an Economical GPS Sensor for SAR and Hover-Hold Missions

Textron Inc’s Bell Helicopter has collaborated with Esterline CMC Electronics to launch a new GPS (Global Positioning System) sensor, to supersede the prevailing, expensive inertial velocity or Doppler sensors that are used in hover-hold systems to be used initially on the Bell 412EP and later on the other models.

Nick Lappos, Chief Technology Officer, Bell, stated that the CMC GPS solution, when added to the 412EP autopilot, gives enhanced results, to improve safety standards in low speed operations and cut down expenses than the older Doppler and inertial solutions. The pricing of this sensor is a fraction of that of the former models. It can be used during emergency medical services (EMS) operations, and in law enforcement procedures. It is advantageous for operators of Bell 412EP, due to its slimness, and convenient installation processes and minus the normal constraints affecting the Doppler system, such as being influenced by under slung devices or glassy water or tall grass.

Its merger with Esterline’s CMA 5024 SBAS (satellite based augmentation system), which has a high update rate and processing power, analyzing the GPS signals, to determine the real velocity dimensions against the reporting changes in the GPS, makes it convenient to use anywhere in the world.

According to Lappos, Bell helicopter, furnishes solutions and products that are not only innovative but also customized to suit their clients’ needs.
