eLORAN Data Segmentation for Faster Multi-Station Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The eLORAN data channel's low bandwidth limits the transmission speed of non-time-critical data, such as almanac information, leading to prolonged transmission times, which can hinder the system's overall efficiency and responsiveness.
Innovation Solution
The eLORAN system divides non-station specific data into subsets and transmits them across multiple stations using a prioritized manner, allowing for multiplexing and sequencing to reduce the total transmission time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If non-station specific eLORAN data is transmitted via a single eLORAN station, then the data transmission is simple to manage, but the transmission time is prolonged
Solution Approach 1:
The patent divides non-station specific eLORAN data into multiple subsets and distributes them across multiple eLORAN stations for simultaneous transmission. This segmentation allows parallel data delivery, significantly reducing the total transmission time compared to single-station sequential transmission, while the control station manages the distribution to maintain system coordination.
2Reliability
If eLORAN data channel transmits time-critical messages with priority, then time-critical messages are delivered promptly, but non-time-critical messages experience delayed transmission
Solution Approach 1:
The patent segments the eLORAN data channel transmissions into priority-based groups, allowing time-critical messages to be transmitted immediately by designated stations while non-time-critical messages are distributed across multiple stations in parallel, reducing their overall transmission delay without compromising time-critical message delivery reliability.

AI summary
An enhanced LOng RAnge Navigation (eLORAN) system may include a plurality of eLORAN stations, each having an eLORAN antenna and an eLORAN transmitter that may transmit data over an eLORAN data channel and may transmit a series of eLORAN navigation RF pulses. An eLORAN control station may generate station specific eLORAN data and non-station specific eLORAN data, divide the non-station specific eLORAN data into nonspecific eLORAN data subsets, and cause each eLORAN station to transmit the station specific eLORAN data and a corresponding non-station specific eLORAN data subset over the eLORAN data channel in a manner to optimize data throughput.
