| 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).

| 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. |

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. |

Optimal use of the EGIS rotor: in the center is a parabolic antenna, on the right an 10cm and an 23 cm antenna and on the left a video camera. In all those different operations the special capabilities of the EGIS rotor with 360 degrees all around sight and 90 degrees Elevantions-Hub (horizon zo zenit) gets used. |

At the vulcano 'Merapi' in Indonesia the EGIS two-axis- anntenna-rotor is used for communication between the aloft sensor station being positioned in dangerous surroundings and the measuring laboratory down in the valley. The device has been developed, built and also installed by the Institute of Geophysics at Hamburg University. Nowadays it is run by the 'Merapi Vulcano Observatory' in Yogukarta/Indonesia. The same device is used at Mount Pinatubu/Indonesia. |
