The ground support equipment (GSE) simulates the space craft electrical
interface. Telemetry data from the instrument is acquired and
processed in real time via custom hardware and logged to 8mm tape. Commands and automated test procedures are delivered to the instrument also. State of health data
are displayed in units familiar to the engineer. The science data are presented graphically to suit the scientist.

The hardware interfaces to the instrument are a mix of commercially
available VME subsystems and custom boards. The data pipeline was
designed to minimize overhead on the Sparc 10.
The software includes a custom Solaris device driver which buffers
data to avoid loss. The back end processing is linked with
NASA/Century computing Transportable Application Environment (TAE).
TAE uses Motif libraries for sophisticated look and feel.
The HIRAAS GSE consists of a
SUN SPARC 10 model 41, 20 inch monitor, 8mm tape
drive, 28 Volt power supply, VME chasis, and an uninteruptable power supply.
The GSE in mounted in two shipping containers that stack during operation.
The GSE is capable of powering and operating the entire HIRAAS experiment
without any electric source.
