SENER participated in the Mars Science Laboratory (MSL) and his contribution was the development of the pointing mechanism of the High Gain Antenna Gimbal (HGAG). The HGAG is a two degrees of freedom, elevation over azimuth, mechanical assembly that... [+]
Antennas and Communications
In recent years, SENER has supplied equipment and participated in various projects involving high and medium gain antenna pointing mechanisms for major scientific missions of the ESA, such as BepiColombo, Solar Orbiter and JUICE. In the development of these systems, SENER designs, verifies and integrates key communications elements in the mechanisms, such as antennas and rotary joints.
As well as skills in telecommunications engineering (radio frequency), the development of these components also requires specialists in the disciplines of mechanical and thermal engineering.
SENER is responsible for the design, development, manufacture, integration, testing and analysis. The tasks fall into two divisions:
- Radiant elements: Medium and high gain antennas
- Passive radio frequency (RF) elements and systems for signal routing
BEPICOLOMBO. Medium Gain Antenna Subsystem and High Gain Antenna Pointing Assembly (MGAMA and HGA APA)
The main objective of the project is to design, manufacture, integrate and test the Medium Gain Antenna Major Assembly (MGAMA) and High Gain Antenna Pointing Assembly (HGA-APA) of the Mercury Planetary Orbiter communications system, which are necessa... [+]
The Medium Gain Antenna Major Assembly (MGAMA) is a medium-gain dual-axis steerable antenna assembly that provides main uplink and downlink communications between the JUICE spacecraft and Earth. The MGAMA will be used in the TT&C (Telemetry, Tra... [+]
The main objective of the project is to design, manufacture, integrate, test and deliver the satellite's complete antenna subsystem. This subsystem comprises four independent devices: High Gain Antenna Major Assembly (HGAMA) In turn, the HGAMA cons... [+]
The K-band ‘I’ Style Waveguide Rotary Joint is aimed to provide radiofrequency connectivity between spacecraft and any steerable antenna operating at K-band (25.5 GHz to 27 GHz range) with WR-34 waveguide interface. Its mechanical and radiofr... [+]
The X-band ‘L’ Style Waveguide Rotary Joint is aimed to provide radiofrequency connectivity between spacecraft and any steerable antenna operating at X-band (7.1 GHz to 7.3 GHz for uplink and 8.4 GHz to 8.6 GHz for downlink) with WR-112 wavegu... [+]
