MiLLennium GPSCard and Enclosures Guide to Installation & Operation 35
VIBRATION (Random Profile)
The MiLLennium will acquire and track satellites while undergoing vibration levels as shown below. This assumes that
it is mounted using full-length clamped rail mounts and that no vibrating object is touching it. It also assumes that
C/N
o
> 45 dB-Hz and that the MiLLennium is in high-dynamics mode. Although not all MiLLennium GPSCards
conform to random vibration templates for RTCA/DO-160C, Section 8.6.2 (Curve C template), MIL-STD-202F, Test
Condition I (Letter A nominal template), and ASAE EP455, Section 5.15.1 nominal template, many do. It is possible to
purchase a pre-screened MiLLennium GPSCard to meet these vibration requests if required. Please consult NovAtel
Customer Service for further information. Note that a MiLLennium GPSCard in a PowerPak II or ProPak II enclosure
does conform.

Typical Mounting Configuration - Mount the GPSCard securely using screws driven through the card’s four corner
mounting holes.
Superior Mounting Configuration - Mount the card using full length clamped rail mounts.
Note: The card is sensitive to any external vibration against it.
