The desired orbit is one with an average altitude no higher than 550 kilometers and an orbital inclination of at least 34 degrees. To accomplish the mission, the two 1.5U cubesats will be deployed from a standard cubesat dispenser and placed into a circular or near-circular orbit. This project is a good example of applying the technology of everyday commercial products to new uses in spacecraft. Spacecraft that need to operate in close proximity to other spacecraft could make use of these low-cost sensors to keep track of the position and motions of other nearby spacecraft or objects. A laser device on each satellite, derived from the system used in a computer mouse, will be used to measure the cross-track motion of the partner satellite, or other objects. Capabilities in proximity operations will enable multiple small spacecraft to operate cooperatively in science or exploration missions, to approach another spacecraft or object in space for observation or servicing, or to connect small spacecraft together to form larger systems in space.Ī small radar system adapted from the automotive industry will be used to determine the distance between the satellites at close range. The second objective of the project addresses the need for low-cost sensors that small spacecraft can use to help them maneuver and operate safely in close proximity to other spacecraft or objects in space.
This system would be beneficial for small-satellite missions that need to transmit large amounts of data but have very limited power available onboard. The communications concept that will be demonstrated is an asymmetric one in which the satellite uses an laser beam to transmit large amounts of data to the ground while it uses a conventional radio-frequency system to receive commands from the ground. Optical communications systems are of interest for use in spacecraft of any size and this project provides an opportunity to advance this technology quickly and at very low cost. For a given amount of communications system power, optical systems, that transmit information using a laser beam rather than a radio signal, offer the potential to greatly increase the volume of information that can be transmitted by a spacecraft. With its first objective, this project addresses the need to increase the amount of data that a small spacecraft can transmit to the ground. This two-year project was initiated in October 2012. The spacecraft for this mission will be two 1.5-unit cubesats, which are satellites with dimensions of approximately 10 by 10 by 16 centimeters and a mass of approximately 3 kilograms. The OCSD project is led by the Aerospace Corporation, in El Segundo, California and is funded by NASA’s Small Spacecraft Technology Program. The Optical Communications and Sensor Demonstration (OCSD) mission will address two crosscutting capabilities of interest to NASA: optical communications system and low-cost sensors for proximity operations with cubesats and other spacecraft. Visualization of one satellite using its radar and laser cross-track sensor to measure the distance and relative motion of the other satellite. Hinged solar panels that can be used to vary the drag force on the satellite are also visible. GUN Mouse ĩ.One of the two identical cubesats that will be part of the OCSD mission. Not sure how well they work as compared to good old standard mouse. These are concept mouse that you can surely get to flaunt the design. Now here are few mouse (concept mouse) that looks anything but mouse. However, mouse that most of us use are decent and very functional. Come on, we use it all the time when using computer.
