Open the web application of each spoke and in the Mesh settings, select
Spoke
from the drop-down list.
When a FiX1 has been designated as a spoke, the web application for that unit offers restricted functionality.
The FiX1 designated as hub retains all functionality. Use the hub to schedule scans, set up surfaces, upload
polylines and configure reporting.
The web application of a spoke only need be accessed to:
•
Change the scan parameters
•
Change the calibration parameters
•
Download raw data (LAS files)
During standard operations, the operator communicates just with the hub. The base file and scanning schedule are
configured only in the hub.
A scan request is sent to the hub. The hub sends a scan command to the spokes, together with an empty grid. Each
spoke runs a scan, fills the grid with elevations and returns the grid to the hub. The hub consolidates data from all
FiX1 units in the network, cleans the data and computes a volume.
Note that all units in the hub-and-spoke installation must be geo-referenced on the same coordinate system so that
the scans of each unit are correctly registered. If this stage is not completed, the scans from each unit will be
mismatched and resulting volumes will be incorrect.

Calibration
Care should be taken not to tamper unnecessarily with settings in the
Calculation
section. Typically, these values
are determined and configured on installation of the FiX1. Thereafter there should be no need to adjust the values
as long as the FiX1 is installed in the same location.
The calibration constants are set in the factory during production. These constants account for mechanical
misalignment of the laser with respect to the FiX1 housing, eccentricity of the planes of rotation and range
innacuracies.
