Downlink Acceleration Analysis
. Due to the constant pressure of the brake spring, the braking torque of the uplink and downlink processes can be considered equal.
So, the median of acceleration peaks, which has more statistical significance than randomly arranged acceleration peaks, is used in vibrational acceleration analysis
. Assuming that n acceleration peaks are observed from the accelerometer, those acceleration peaks are expressed as

In order to ensure velocity stability of the rocket guides, acceleration analysis
of the links in kinematic chain [O.sub.1]CDE was performed with the aim to derive functional relationships between kinematic parameters of links [l.sub.3] and [l.sub.12] and position angle [[phi].sub.4] in case angular velocity [[omega].sub.4] is set.
Sherborne Sensors has announced the debut of its A323 'L' Series, a range of rugged, ultra-low range gravity referenced linear servo accelerometers with 4-20 mA (closed loop) output, designed for use within low acceleration analysis
, structural health monitoring, flight test, and civil engineering applications.
