Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current IoT solutions face challenges in providing global connectivity, especially in remote and underserved areas due to reliance on existing infrastructure, which limits coverage and is costly and inefficient, particularly in regions like the North and South Poles, deserts, and low-density population areas.
Innovation Solution
A space-based communications network utilizing a constellation of CubeSats in different orbits, equipped with software-defined networking and network function virtualization, forming an ad hoc network that enables direct communication between satellites and with ground stations, providing a low-cost, scalable, and redundant connectivity solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional satellite systems are used to provide global communications coverage, then coverage area is improved, but development cost and device complexity increase significantly
Solution Approach 1:
The satellite network is segmented into multiple small CubeSats (6U, 12U, 18U configurations) instead of using a single large traditional satellite. Each CubeSat is a standardized unit that can be manufactured independently and deployed in constellations, reducing individual unit cost while achieving global coverage through multiple units working together.
Solution Approach 2:
The system employs low-cost, small-scale CubeSats that can be rapidly manufactured and deployed. These CubeSats use commercial off-the-shelf components and standardized bus designs, making them economically viable to produce in large numbers. The system accepts that individual CubeSats have limited operational lifetimes but compensates through continuous deployment of replacement units, maintaining overall network coverage.
2Area of stationary object
If traditional satellite systems are used to provide global communications coverage, then coverage area is improved, but development time increases due to long cycles
Solution Approach 1:
The CubeSats are designed using preliminary standardized architectures and commercial off-the-shelf components, allowing for rapid prototyping and deployment. Software-defined radio and pre-configured communication protocols enable satellites to be prepared and launched much faster than traditional custom-built satellites, reducing the development cycle from years to months.
Solution Approach 2:
The system employs dynamic reconfiguration capabilities where CubeSats can adapt their communication parameters, orbital positions, and network roles in real-time. This dynamic approach allows the network to self-organize and maintain coverage as satellites are deployed or decommissioned, eliminating the need for lengthy re-planning periods.
3Reliability
If infrastructure-based IoT solutions are used, then connectivity reliability is improved in urban areas, but adaptability to remote areas deteriorates
Solution Approach 1:
The CubeSat communication system provides universal service across all geographic regions, functioning equally well in urban, rural, and remote areas including the Arctic and Antarctic. The satellites directly beam communication signals to ground terminals without requiring terrestrial infrastructure, making the system universally applicable regardless of location or existing infrastructure density.
Solution Approach 2:
The CubeSats act as intermediary nodes between ground terminals in remote areas and the global internet infrastructure. Instead of requiring ground-based infrastructure in remote locations, the satellites serve as mobile intermediaries that relay communications, enabling connectivity in areas where traditional infrastructure cannot reach.
4Ease of manufacture
If CubeSats are deployed in low earth orbits, then manufacturing cost is reduced, but network complexity increases due to orbital management
Solution Approach 1:
The CubeSat network implements self-service through autonomous orbit determination and communication protocols. Each CubeSat independently tracks its position, identifies visible satellites and ground terminals, and manages its own communication sessions without requiring complex centralized control. The network self-organizes through distributed routing algorithms that automatically adapt to changing orbital configurations.

AI summary
A space-based communications network (100) includes at least one central ground station (116) having a transceiver that is configured to communicate with satellites, such as cube satellites (110). The cube satellites (110) form an ad hoc network of orbital cube satellites, in which each of the cube satellites (110) communicate with each other. One of the cube satellites communicates with the ground station (116). A ground-based control system (1000) communicates with the central ground station (116). The control system (1000) continuously determines a configuration of the ad hoc network (100) and communicates network control information for the cube satellites (110) to maintain communications in the ad hoc network (100). The cube satellites (110) disseminate the network control to each other via the ad hoc network (100).
