Mount the SPAN System Components

1. Mount the antenna. See Mounting the GNSS Antenna.

2. Mount OEM7 receiver. See Card Installation Overview or PwrPak7 Installation Overview for information about installing an OEM7 receiver.

3. Mount the IMU. See Mount the IMU.

4. Install the UIC in a secure enclosure to reduce environmental exposure and RF interference. If there is sufficient space, the UIC can reside in the same enclosure as the receiver.

   Use M3 pan head stainless steel screws to secure the UIC to its mounting location. See UIC Mechanical Drawings for the UIC dimensions.

   Ensure the UIC is mounted close enough to the IMU so the interface cable can reach both devices. For the length of the interface cable, refer to the specifications for the IMU in IMU Technical Specifications.

   Ensure the mounting location provides at least 5 mm of clearance below the board to allow for components on the bottom of the UIC.

   Ensure all standoffs are properly installed and the mounting location is flat.
   The amount of board deflection (bow and twist) must not exceed 0.75%. For example, on the UIC which is 100 mm long and 113 mm wide, the deflection along the length must not exceed 0.75 mm and the deflection along the width must not exceed 0.85 mm.
