The schematic diagram of the trial is illustrated in Figure 1, where the field sensor data is interconnected to an OQ TECH terminal through Bluetooth before forwarding the sensed data to the corresponding satellite. The trial setup can be categorized into two main segments, namely Ground and Space, where both can be summarized as follow:

The readings were collected every 2 hours from the sensors where the transmitted packet contains of the following:
Temperature
2 bytes
Humidity
CO2
GPS
8 bytes
Timestamp
4 bytes
Measurement index
1 bytes
Status code
An ultra-high reliability connection was achieved as all the transmitted data frames were successfully received and decoded at the ground station. The decoded data were then transmitted to the cloud-based dashboard that shown in Fig. 4. Additionally, a date throughput of 9.6 Kbps and an overall latency of 10 millisecond (ms) were attained, respectively. In conclusion, our successful trial has demonstrated that, the LEO-aided 5G -IoT satellite can be used to provide coverage to remote areas in harsh environments.
