GPS Antenna (all systems)
Keep the ceramic antenna dome clean and free of scratches,
as antenna dome imperfections will impact the GPS receiver's
performance.
Inspect all antenna cables and connections once a year
for loose cable ends, frayed cable insulation and scratched
or damaged antenna surfaces.
Replace any damaged components.
No further maintenance is required.
IMU (all systems)
The IMU is a sealed unit and requires no maintenance. The
IMU LED on the PCS front panel will indicate if the IMU has
had a catastrophic failure. Should this LED fail to light,
inspect the IMU cable for damage. In either case, contact
Applanix Customer Support. The IMU is a sensitive instrument
and must not be subjected to excessive shock or vibration.
The IMU has a shock gauge that will trip if the shock limit
is exceeded. Extreme care should be exercised when performing
any routine maintenance in the vicinity of the IMU.
PCS (all systems)
The PCS requires very little maintenance if it is protected from
moisture and dust. Ideally the PCS should be mounted in a vibration
isolated 19" rack. If it is not, the unit should be examined
for vibration stress (such as loosened screws). Tighten all screws
and connectors. Inspect all cables for wear or damage. Inspect
cable tie-downs to ensure that cables are secured and out of the
way.
DMI (POS LV and POS TG only)
Clean the DMI regularly by spraying with water to prevent dirt
build-up. Because the unit is exposed to significant vibration,
the cAollet bolts and bracket mounting screws should be inspected
regularly for tightness.
The DMI LED on the PCS front panel will indicate if the DMI has
had a failure. Should the DMI LED fail to flash when the vehicle
is in motion, inspect the DMI cable and cable connectors for damage.
In either case, contact your Applanix customer support representative.
