At LAPAN (Indonesian Aviation- and Aerospace-Agency) in Rancabungur (Satellite Technology Center) the EGIS Rotor is going to be used for positioning of three antennas at the same time: a VHF-, a UHF- and a S-band antenna. The installation will be of use for communication with earthnear, circulating satellites as for example "Tiungsat 1" (uplink VHF 144 MHz and downlink UHF 430 MHz) and "Amsat AO40" (uplink UHF 430 MHz and downlink S-band 2400 MHz).

Altogether this rotor (360° AZ/90° EL) carries:
  • 140 cm Ø mesh-dish for 13 + 23 cm
  • 90 cm Ø offset for 3 cm/10 GHz
  • 30 cm Ø primfocus for 1.5 cm/24 GHz
  • 21 element-yagi for 70 cm
  • mounting-devices plus frameworks (vertical carrier!)
  • all transverters and power-amplifiers in casted alu-housings, simultaneous AZ/EL movements (55 kg), antennas/rotor are located at the roof of an 8-story building, distance from the shack approx. 40 m

A very interesting rotor application can be found at RBB "Radio-Berlin-Brandenburg" (former "SenderFreiesBerlin"): ENG vehicles in the city and in the region are controlling EGIS rotors via notebook computers and cellular radio connections. These rotors are mounted on a high building at the broadcast controll center. A directional microwave antenna can be adjusted automatically via notebook – GSM – modem – control unit – rotor right onto the ENG vehicle. On duty are 4 rotors – one for each quarter of the compass rose respectively.

Photo 207 The CubeSatellite "Compass 1", which
has been developed, built and taken
into space by 'Aachen University of Applied
Science' will also be monitored and controlled
from there via an uplink station. As this satellite
belongs to the LEOS, the antennas must be
continuously tracked to communicate with the
satellite. This task was taken over by an EGIS
Two-axial-tracker CL (Az = 360° & El = 90°)
– successfully.
