Abstract
Methods and systems for satellite payloads are provided. A first system is based on using a focal plane array tiles with a reflector. A second system uses active lens tiles, focal plane array tiles and the reflector. A third system includes active reflector tiles, focal plane array tiles and the reflector. Yet another system enables beam power sharing by selectively providing power to solid state power amplifiers used in satellite payloads. Another system uses multiple micro-satellites for providing satellite coverage for an area.
Claims19
A satellite payload system, comprising:
- a plurality of focal plane array tiles interfacing with a reflector for receiving and transmitting signals;
- wherein a focal plane array tile of the plurality of focal plane array tiles includes a receive segment, a transmit segment and a switching module;
- wherein the receive segment includes a first filter that isolates a receive signal from a transmit signal, a low noise amplifier that amplifies the receive signal and a first frequency conversion module that converts frequency of the received signal to an Intermediate Frequency;
- wherein the transmit segment includes a second frequency conversion module that converts a frequency of the transmit signal to a Radio Frequency;
- wherein the switching module receives an output from the receive segment and switches the output to another focal plane array tile;
- and
- wherein the receive signal and the transmit signal are isolated using orthogonal polarization between a receive element at the receive segment and a transmit element at the transmit segment.
