Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of unmanned aircraft (UAS) in recreational and commercial activities necessitates better integration into the National Airspace System, with a need for remote identification technologies that can be accessed by various stakeholders, including pilots, law enforcement, and the public, while addressing limitations of existing communication protocols like WiFi and V/UHF.
Innovation Solution
A modular multi-mode remote identification broadcast system (RBS) utilizing WiFi direct, RF direct (V/UHF), and radio relay modes, allowing flexible configuration to serve different constituencies with varying distances and equipment availability, incorporating GPS data, and data integrity checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If WiFi protocol is used for remote identification broadcast, then ease of access for general public is improved, but transmission range is limited
Solution Approach 1:
The system segments the broadcast function into two distinct protocols: WiFi for short-range public access and V/UHF for long-range transmission. This allows each protocol to operate in its optimal range without compromise, with WiFi serving nearby devices and V/UHF extending coverage to distant receivers.
Solution Approach 2:
The broadcast module is designed with multi-functionality to support both WiFi and V/UHF protocols simultaneously. This universal capability enables the single device to serve multiple constituencies (general public, public safety, law enforcement) with different range requirements using appropriate protocols.
2Length of stationary object
If V/UHF protocol is used for remote identification broadcast, then transmission range is improved, but receiver availability decreases
Solution Approach 1:
The system segments the receiver base by protocol type: WiFi receivers (ubiquitous smartphones, tablets) for short-range access and dedicated V/UHF receivers for long-range access. This segmentation allows each receiver type to be optimally matched with its corresponding protocol and use case.
Solution Approach 2:
The broadcast module acts as an intermediary that translates identification data into both WiFi and V/UHF formats, enabling seamless communication with diverse receiver types. Public safety and law enforcement devices use V/UHF for extended range, while general public uses WiFi through common devices.
3Device complexity
If single-mode broadcast system is used, then device complexity is reduced, but adaptability to different constituencies is limited
Solution Approach 1:
The broadcast module incorporates dual-protocol capability (WiFi and V/UHF) within a single integrated device, enabling it to serve multiple constituencies with different range and accessibility requirements. This multi-functionality maintains relatively simple device architecture while dramatically expanding adaptability.
Solution Approach 2:
The system dynamically selects and activates appropriate broadcast modes based on operational requirements. The broadcast module can operate in WiFi-only mode for urban public access, V/UHF-only mode for remote public safety operations, or both modes simultaneously for comprehensive coverage.

AI summary
The invention discloses a system and method of monitoring of unmanned aircraft systems (UAS) operating in the national airspace system (NAS). The multi-mode remote identification system (‘remote ID’) comprises an airborne sensor system having a multi-mode communication function adapted to remotely communicate the remote identification data of the unmanned aircraft system (UAS) to interested parties on the ground. The system includes the ability to communicate the UAS data using means compatible with smart phones or other portable personal computing devices for example using WiFi or Bluetooth communications. The system also discloses a means for communicating the UAS data over greater distances using V/UHF communication techniques and then relaying the data to end users using consumer compatible communication protocols such as WiFi and Bluetooth.
