Model Change Description
6003L 1.5m Antenna: Initial Version. Limited Azimuth axis; 3 separate servo
amplifiers; Az pot; EPROM
6003AL 1.5m Antenna: Limited Azimuth axis; 3 servo amplifiers integrated into
PCU; Az encoder in azimuth motor; flash-programmable.
6003AL Corrected the following antenna positioning problem caused by ship motion
at sea: when elevation > 45 deg and ship rolls, dish moves to 0 deg elevation;
azimuth and cross-level positions are lost and antenna fails. This prom
allows the antenna to experience large ship rolls without loss of position.
6003AL Corrected motor gains for sea-going operation.
6003AL Corrected 3-axis motion (cross-level).
