KONGSBERG one of the leading global technology corporations and premier supplier of defense and aerospace-related systems delivering mission-critical solutions has introduced a new Antenna Pointing Mechanism for both LEO data downlink antennas and Inter Satellite Link antennas.<\/p>\n
The KARMA-7 FG is a state-of-the-art space-qualified Antenna Pointing System that consists of two main sub-systems, the mechanism with a traditional azimuth over elevation configuration, and the RF system. The RF system consists of the RF feed network (rotary joints and waveguides), and the antenna with the polarizer. <\/p>\n
The mechanism is realized using two identical Small Rotary Actuators (SRA) based on the Kongsberg EuroKARMA drive-line. The mechanism has been developed to accept RF sub-systems with single or dual polarization, accommodating either X-band or Ka-band.<\/p>\n
The KARMA-7 FG consists of a two-phase bipolar stepper motor and a coverage of \u00b1210\u00b0 in azimuth and \u00b190\u00b0 in elevation. It has a rotational speed capability of 17 Deg\/s and a full step resolution of 0.012 Deg. The mechanism has a frequency range of 25.5 to 27 GHz with a system gain of 31 dBi.<\/p>\n
The development and qualification of the APM are performed under an ESA GSTP. KARMA-7 was selected for the MetOp-SG Ka-band data downlink. Each of the 6 MetOp-SG satellites carries two APMs, one nominal and one redundant, for a total delivery to MetOp-SG of 12 Flight Models and one spare. <\/p>\n
