A New Measurement Method for BDS Inter-Satellite Link Based on Co-Frequency Co-Time Full Duplex System [PDF]

Sensors
To meet the urgent need for high-precision ranging and large-capacity transmission in the current BeiDou-3 inter-satellite link system, this paper proposes a novel two-way measurement method based on Co-frequency Co-time Full Duplex (CCFD) system.

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping [PDF]

Advanced Science, EarlyView.
This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.

Hera Inter-Satellite link Doppler characterization for Didymos Gravity Science experiments

, 2022
While ground-based spacecraft radio tracking is a well-established technique, the use of miniaturized space-to-space inter-satellite links, capable of determining the Doppler shift due to the relative line-of-sight velocity between two spacecraft, has ...

An IP-ERN architecture to enable hybrid E2E/ERN protocol and application to satellite networking [PDF]

, 2012
We propose an architecture based on a hybrid E2E-ERN approach allowing ERN protocols to be inter-operable with current IP-based networks. Without introducing complex operations, the resulting E2E-ERN protocol provides inter and intra protocol fairness ...

A Community-Based Construct Method for an Inter-Satellite Communication Network of Satellite Swarm

Entropy, 2023
An inter-satellite communication network of satellite swarm (ICNS) is created if the members of a satellite swarm communicate with each other via inter-satellite links (ISLs). ICNS can be constructed using the theory of complex networks. A link community
