NI 9467 Overview

The NI-9467 is a stationary GPS timing module for C Series platforms. It provides

accurate timing and geographic location information to the C Series host, which

enables synchronization of C Series systems.

Start-Up Behavior

At start-up, the NI-9467 automatically begins determining its location through a

process known as self-survey. During the self-survey, the module computes a

location fix every second and averages the locations at the end to obtain a more

accurate location. After the self-survey, the NI 9467 no longer computes new

location fixes; it uses its known location and satellite signals to generate accurate

timing signals.
Like all GPS receivers, the NI-9467 requires GPS satellite ephemeris and almanac

data to compute accurate time and location. The ephemeris is detailed orbital

information about each satellite (where each satellite is expected to be at a given

time). The almanac data describes the general health of each satellite (for example,

the receiver must not use signals from satellites marked as unhealthy) and contains

coarse orbit information. The GPS satellites broadcast the ephemeris and almanac

data every 30 seconds. Therefore, it usually takes approximately 30 seconds for it to

receive the ephemeris and almanac data and start computing location and timing

fixes.

Status LED

The NI-9467 has a front panel LED to indicate status. The following table describes

the meaning of each LED pattern.
