6.2 Hardware Safety & Mechanical Limits - Core
Safe operation of the AvL antenna system is essential and it is critical that the AAQ software be configured
appropriately. Many limits on motion of the antenna are set by physical switches that are monitored by the
AAQ ACU. Others are set by software configuration parameter values that are compared to a particular
system variable or sensor output. Most of these are set in the factory, not subject to change and require a
high privilege level to view and modify. A small group is subject to change after the antenna leaves the AvL
factory due to later mounting of CFE hardware on the antenna system and installation of the antenna onto
the integrator’s vehicle or base support. It is this small group of parameters that is addressed in this section.

~IMPORTANT~
When the antenna is pointing at low look angles, the movable feed boom, along with
any CFE BUC(s) that may be mounted on it, is located in close proximity to the
stationary base support. Safe elevation angles must be determined for normal
operation of the antenna. This includes movement while the antenna is deployed and
when it reaches the stow position. All elevation angles associated with these
parameters are Ped-EL values, which are referenced to the antenna mechanical
interface and are not subject to adjustment due to tilt compensation. Special attention
