GDU(Gun Data Display Unit)
The GDU is a handheld device that automates the coordination and communication of FDC missions. Based on the known location, the MBCE and GDU can compute send and receive specific fire data for each gun. The GDU provides quick and reliable calculations for fire to the GDU equipped Gun as well as information on mission initiation, target, ammunition and completed mission data to Control. This information is sent using wireless communication between the MBCE and GDU. The MBCE to GDU communication is via secure WAN technology. The MBCE to Control communication is via a combination of WAN and radio modem. The automated and real-time display of firing calculations to the GUN allows for more coordinated, efficient and accurate calls for fire and better documentation of the event.
