Digital Storage Unit

(DAAS-HD-001-01)
The RF front ends usually have data acquisition and logging devices that feed into the RAM. RAM cannot store large quantities of data, while hard disk-based storage devices can accommodate data transfer rates up to 200 MBps and have a total storage space of several terabytes. You can purchase these systems off-the-shelf and configure them for data acquisition, storage applications, and the recording and post-processing of direct or simulated GPS signals.

System configuration: RAID assembly of eight hard drives with associated software and hardware interface. The minimum system can store one hour of data (total 720 GB) at 120 MBps. The complete system offers standalone data acquisition and storage in either a tabletop enclosure or a rack-mounted enclosure. The data-acquisition portion directly interfaces with the RF front ends. It allows throughput up to 200 MBps, DIO interfaces, and analog inputs/outputs. For navigation communities, the units have dual-frequency downconverters and upconverters and appropriate P-code and M-code.
