ANTENNA DEPLOYMENT & POINTING MECHANISM (ADPM)

Purpose:

Rotates antenna interface flange relatively to ADPM baseplate in two perpendicular planes within the specified ranges of operating and stowed angles

Performances:

Rotation angle about each axis, ° ± 15 Rotation speed, °/min 0 – 7 Rotation angle measurement error for each axis, arcsec, no more 60 Angle sensor Optical (OEDU-3, error 10″) Torque achieved for each axis, N·m, no less 30 Self-braking torque with motors powered OFF for each axis, N·m, no less 5 Load moment of inertia, kg·m2 30 Operating temperature range, °C OFF state –65 to +70 ON state –30 to +60 Operating life expectancy over 15 years, h, no less 88 000 Mass, kg 7,2 ±0,2
