20230107068 · 2023-04-06 ·

Systems, devices, methods, and computer-readable media for location determination of an orbiting device. A method can include receiving measurement data from a monitor device, the measurement data representative of a position of an orbiting space object with a mechanically moveable antenna, receiving, by processor circuitry, mission data indicating orientation of the antenna is changing from a first orientation to a second, different orientation by a specified time, determining, based on the mission data, an inter-signal correction (ISC), applying the determined ISC to the measurement data resulting in corrected measurement data, providing the corrected measurement data to a Kalman filter, and receiving, from the Kalman filter, a position estimate of the orbiting space object.

Resonator with a dielectric element including first and second chambers therein connected by a channel, wherein a liquid crystal having an adjustable level fills the first and second chambers and the channel

A dielectric element for a resonator and a corresponding resonator are described. The dielectric element has a first chamber and a second chamber, which are fluidically connected to one another by a connecting channel. A liquid crystal is contained in the first chamber, a gas is contained in the second chamber. Changes in the volume of the liquid crystal can be compensated by a change in the volume of the gas, because the liquid crystal can move in the connecting channel. Consequently, such a resonator can be exposed to greatly fluctuating temperature ranges without requiring any further compensation for temperature-induced changes in the volume of the liquid crystal. The dielectric element can also be hermetically closed to complete the production process.

Articulated mechanism and articulated aiming system comprising the mechanism

An articulated mechanism is included in an articulated pointing system. The articulated mechanism includes first, second, and third spherical joints, and a first, second, and third lever. The first and second spherical joints are linked by the first lever. The first lever includes a first projecting portion. The first and third spherical joints are linked by the second lever, the second lever including a second projecting portion projecting in an opposite direction of the first projecting portion. The second and third spherical joints are linked by the third lever, such that the longitudinal axes of the first lever and of the second lever are perpendicular. The articulated pointing system includes a basement platform and a mobile platform joined by two articulated hinges. The hinges are moved by actuators. The articulated mechanism has the first lever attached to the mobile platform and the second lever attached to the basement platform.

Interlocking, reconfigurable, reconstitutable, reformable cell-based space system

Cell-based systems may interlock in a reconfigurable configuration to support a mission. Space systems, for example, of a relatively large size may be assembled using an ensemble of individual “cells”, which are individual space vehicles. The cells may be held together via magnets, electromagnets, mechanical interlocks, etc. The topology or shape of the joined cells may be altered by cells hopping, rotating, or “rolling” along the joint ensemble. The cells may be multifunctional, mass producible units. Rotation of cell faces, or of components within cells, may change the functionality of the cell. The cell maybe collapsible for stowage or during launch.
