Back-plane connector for cubesat
A back-plane connector connects component boards for a cubesat with a processing unit and a board connector electrically connected to the back-plane connector. The board connector mates with complimentary connectors on the component boards. The arrangement facilitates assembly, testing and operational reliability. An image capture system may be included and has an image capture device with a multiplexer for interactive collection and storage of image and video data.
1. A cubesat configured for orbital imaging, comprising:
an image capture device; and
a board disposed in a satellite frame of the cubesat, the board including:
a processor;
a memory device having two states, including a first state in which the memory device forms data communication with the image capture device for recording an image captured by the image capture device in the memory device, and a second state in which the memory device forms data communication with the processor for outputting the recorded image to the processor; and
a multiplexer for transitioning the memory device between the two states in a manner such that:
the multiplexer establishes a first connection between the image capture device and the memory device;
the processor outputs an instruction to power on the image capture device and capture image data
the memory device receives the captured image data from the image capture device in the first state via the first connection;
the processor outputs an instruction to power off the image capture device after the image data is captured;
the memory device is powered off after the processor outputs the instruction to power off the image capture device;
the multiplexer establishes a second connection between the memory device and the processor;
the memory device is powered on before the memory device outputs the image data to the processor via the second connection;
the processor detects the memory device before the memory device outputs the image data to the processor via the second connection; and
the memory device outputs the image data to the processor in the second state via the second connection after the processor detects the memory device.
2. The system of claim 1 , wherein image capture control instructions are stored in said memory and retrieved by said image capture device for implementation.
3. The system of claim 1 , wherein the processor is in communication with said image capture device to transmit instructions regarding camera settings to implement video and image data collection.
4. The system of claim 1 , wherein the memory device receives image data from the image capture device and said processor retrieves said image data for transmission to one or more remote receivers.
5. A method of capturing image data from an image capture device located on a cubesat in orbit, comprising the steps of:
establishing a first connection, by a multiplexer, between a memory device and the image capture device, the memory device disposed on a board positioned in a satellite frame of the cubesat;
outputting, by a processor of the board, an instruction to power on the image capture device and capture image data;
receiving, by the memory device, the captured image data from the image capture device, via the first connection;
outputting, by the processor of the board, an instruction to power off the image capture device after the image data is captured;
powering off the memory device after the processor outputs the instruction to power off the image capture device;
establishing, by the multiplexer, a second connection between the memory device and the processor;
powering on the memory device before the memory device outputs the image data to the processor via the second connection;
detecting the memory device by the processor before the memory device outputs the image data to the processor via the second connection; and
outputting the image data by the memory device to the processor via the second connection after the processor detects the memory device.
