Research Topic Description, including Problem Statement:
Space is a new domain for the Internet of Things. Internet of Space Things systems integrate ground-based nodes with space-based infrastructure and terrestrial broadband backhaul. Several UK-based service providers are poised to launch services. However, the IC is interested in understanding the trade-offs needed to design Internet of Space Things (IoST) systems for distributed ground sensors including command and control in circumstances where the very best performance can be achieved with the least commitment of power both on the ground and in orbit. At the same time, development and operating costs need to be kept to a minimum. For this reason, the IC is interested in defining the design criteria for two-way LEO satellite communications using readily available radio chipsets where power, weight and size are all constrained.
Aspects to be taken into account include:
Some work has been done in this topic and is in the public domain on the space-ground down link, this project will explore the ground-space up link also and combine the paths two to show how efficient and effective two-way communications using short datagrams can be designed. Reciprocity over the paths is not assumed.
Key outcomes are:
Example Approaches:
Long Range (LoRa) is a popular choice for the one-way space-ground link with several choices of parameters and waveforms in use by operators (tinygs.com). The LoRa signal is tolerant of the magnitude of doppler shift encountered in LEO satellites. It is possible to use the cyclic redundancy check (CRC) to plot a Receiver Operating Characteristic (ROC) curve for LoRa datagrams received on the ground. However, this may be misleading as it relies on a linear relationship between SNR and decode success – this is clearly not the case as the signal processing is non-linear. Also, the uplink path (ground-space) is not taken into account, and there is no guarantee of reciprocity. So alternative performance criteria are needed.

A variety of chipsets are available ranging from ultra-narrowband ultra-low data rate through to broadband burst transmissions. This repertoire needs to be systematically evaluated.
Relevance to the Intelligence Community:
Internet of Satellite Things is an important enabling technology for data transfer and command and control in the field, yet designs in use are ‘vernacular’ and have little published about them. Commercial services are not necessarily in the right form factor or with the right link performance. The aim is to know how to design suitable two-way LEO satellite communications that are both power efficient and secure.
