The paper includes a description and technological issues of the different sub-units that compose the mobile payload and the European Space Agency (ESA) related activities. Emphasis is put on the digital part of the payload (the Payload Processing Unit), and in particular on the digital ...
The launch vehicle payload volume geometry limits the maximum diameter of fixed antennas. This limitation can be circumvented by using deployable apertures. Deployable reflectors have been used since the 1970s (e.g., ATS-6). Currently, deployable reflectors for the MSS at L-band are in use ...
1. Nongeostationary orbit satellites: BeiDou’s medium Earth orbit satellites and inclined geostationary orbit satellites adopt the improved platform of the DFH-3 communication satellite and all the payloads are RNSS loads. 2. Geostationary satellites: these satellites adopt the improved DFH-3 platform...
In the next section, a brief description of problem definitions is presented, followed by the introduction of the proposed BiLSTM network architecture. Then, the application to meteorological satellite based on BiLSTMdeep learning model and our experimental results are shown. Finally, conclusions are ...
Satellite Payload|Satellite Cellular Service|High Definition Support:Delivers crystal-clear 1080P HD visuals, enhancing your viewing experience. Wireless Connectivity:Equipped with a built-in 2.4G WIFI module and Ethernet support for seamless streaming. ...

Due to the limitations of the LEO orbit and observation swath of the sounding payloads, it is difficult to achieve continuous and dynamic monitoring of regional area inside the countries. The existing carbon source monitoring satellites can only reach the revisit cycle of 1 month, and the carbon...
16.3.1Data Description Balloon andsatellite instrumentsare used to measure the state of the atmosphere on a routine basis. After initial checks, and sometimes statisticalinversion techniques, the satellite measurements yield atmospheric variables (such as temperature) as functions of altitude, geographical...
As the power and mass available for the communications payload has increased, those payloads have grown in capability, and the overall system trade-offs have shifted toward placing more burdens on the spacecraft payload. Onboard processing, especially for the communications signals but also for the...
