For other projects such as the Corpus Christi Real-Time Navigation System
and the Freeport FlowInfo System
, CBI-DNR has developed a data collection computer using industry-standard PC-104 computer components. A typical PC-104-based data collection computer consists of an Intel 486 or Pentium processor, 16 megabytes of RAM, and at least 20 megabytes of solid-state hard disk space. The data collection computer runs a modified form of the Linux operating system; this allows the use of a rich set of software development tools and provides a robust multitasking environment for controlling sensors, storing data, and doing on-site processing such as data compression for transmission over bandwidth-limited communications channels.
