Objectives
The objectives of the project:
-
Demonstrate satellite-based IoT services in the frequency range 1500-5000 MHz
-
Develop and deploy protype user terminals supporting the demonstrations
-
Support preparatory work in the ITU with studies and results from measurements and IoT trials
Challenges
Some of the key challenges to this project are:
-
Wide bandwidth covering multiple types of frequency usage. This requires the front-end to have a very high dynamic range.
-
Furthermore, the wide bandwidth reduces component availability and performance
-
Short timeline for submitting studies to WRC-27 preparatory process.
System Architecture
Our proposed experimental IoT system to be used for the end-to-end experiments consists of the following elements:
-
A LEO satellite with IoT SDR payload and other payloads
-
A prototype user ground terminal built around a SDR hardware platform with mobile broadband connectivity for command and control
-
KSATLite compatibility
-
IoT experiment control and spectrum analysis software
-
A cloud server for storage of I/Q data
Plan
Phase 1 (June 2022 – November 2022):
-
Definition of use cases, operational concepts and requirements
-
Definition of requirements for the experiment, satellite and ground segment
-
Identification of requirements for satellite bus.
Phase 2 (December 2022 – May 2026):
-
Experiment, satellite and ground segment preliminary design (December 2022- June 2023)
-
Experiment, satellite and ground segment development and test (June 2023 – December 2023)
-
Embarkation of experiment payloads on host spacecraft and test plan consolidation (December 2023 – September 2024)
-
Experiment Execution (September 2024 – March 2026)
-
Lessons learned, exploitation plans and Final review
There will also be two separate activities happening alongside phase 1 and 2, but outside the scope of this activity:
-
Host Satellite Construction
-
IoT SDR Payload Construction
Current Status
-
Project kick-off June.2022
-
Bids received on host satellite construction
-
IoT SDR Payload design at very mature stage
-
Awaiting approval for proceeding to Phase 2.
