| The increasing demand for real-time Earth observation and geointelligence services has driven the development of new aerial and spaceborne platforms capable of providing persistent and wide-area monitoring. High Altitude Pseudo-Satellites (HAPS) and Low Earth Orbit (LEO) satellites are emerging as key elements in future observation architectures due to their flexibility, coverage, and reduced deployment costs. However, the efficient transmission of observation data from these platforms remains a major technical challenge due to limited bandwidth, high latency, and strict power constraints, specially from HAPS to LEO communication satellites.
The recent inclusion of Non-Terrestrial Networks (NTN) within the 5G standard framework offers a promising solution for global connectivity of aerial platforms (i.e., HAPS). Nevertheless, conventional IP-based communication protocols introduce significant overhead, which limits their efficiency in NTN environments, particularly for small payloads or fragmented data when using protocols like NTN NB-IoT. Static Context Header Compression and Fragmentation (SCHC), standardized by the IETF, has been specifically designed to address these limitations by enabling header compression and fragmentation optimized for constrained links. This project proposes the development, validation and evaluation of optimized data transmission using SCHC from a HAPS to a LEO satellite using NTN NB-IoT. The HAPS generates two kinds of data, i) processed earth observation image data and ii) telemetry and control data, which is compressed and fragmented before being send using the NB-IoT link to the LEO satellite, which then forwards the information to the ground station. The project will focus on the use of real devices running an implementation in a testbed emulating satellite coverage conditions. The work contributes to the evaluation and validation of SCHC as an enabling technology for efficient Earth observation data delivery over NTN links. Performance evaluation will focus on parameters such as packet delivery ratio, latency, throughput, reliability, and protocol overhead. |
