The RPA provides the ability to configure all parameters for the RF-7800S, including station type definition, net planning, and key management. Multiple nets can be configured and stored in a plan file on a PC or removable media for easy distribution to the radio via USB. The SUS can be installed on either a PC or PDA. It allows for a userfriendly radio interface, real-time editing, and real-time distribution of the radio plan file including the ability to perform radio firmware upgrades. The Utility Software provides the Harris proprietary Ground Force Tracking GPS system. Squad or platoon leaders are able to track the location of their troops, displayed on customer-provided map overlays. The SUS can perform built-in radio test and ongoing reporting of radio status. The software enables the user to perform in-field modification of radio plan files, distribution and refill the radio. Programming kits are provided on a CD and flash memory device and contain a USB fill cable to enable USB connection to the Secure Personal Radio. The flash memory device can also be used for in-field distribution of plan files.
