Recorder, Integrated Processor, Router (RIPR ©)

CALCULEX RIPR technology is designed to provide a range of cutting-edge data recorder models suitable for missions on land, air, sea and space. Our recorders are engineered to meet the toughest conditions, making them ideal for use in harsh environments. Their solid-state memory modules ensure optimal performance at high data rates and across numerous parallel ports and busses, while their low Size, Weight, and Power (SWaP) architectures make them easy to fit and install.

Our recorders offer a range of digital and analog interfaces, including, but not limited to, MIL-STD-1553, PCM, UART, and Ethernet. With flexible configurations and modular designs, CALCULEX RIPRs Are Modifiable Commercial-Off-The-Shelf (M-COTS) products allowing systems integrators to match their requirements. Discover our range of advanced data recorders, processors and routers today and experience the CALCULEX difference.

All CALCULEX RIPRs utilize a modular open standard for hardware architecture. The data recordings command, control and status application programming interface (API) comply with the IRIG 106 standard co-authored by CALCULEX and the USAF.
