KaPDA - Gimbal

KaPDA 2-Axis Gimbal

  • Can track LEO to GEO, LEO to ground, LEO to LEO.

  • Integrated gimbal controller with serial interface.

  • 50 to 100 cm diameter reflector options available.

  • Polarization capabilities: RHCP, LHCP, V and H.

  • RF tested to 51 GHz. Options at X, Ku, K, Ka, Q, and V bands.

  • Vibration tested to 8.69 Grms.

  • Antenna is TRL 9: KaPDA launched July 2018 to LEO.  Deployment and radar operations fully successful.

  • Gimbal assembly is TRL 6.  First flight scheduled Q3 2022.

  • LNA and PA can be directly attached to feed to reduce RF losses.

  • Elevation axis can be counterbalanced such that center of gravity is static during gimballed antenna operations.

  • US Patent 10,256,530 B2 and pending US 62/782,599.
