- 초록
- This paper presents the structure of terminal ASIC chip with low speed, low power, and small characteristics for satellite IoT transmission. The external connection with the sensor, flash external, and tuner will be made centering on the ASIC chip. Three transmission waveforms, such as the LoRa, I-LoRa, and LoRa-E, will be used to send the collected data to LEO satellite. As a result, the data collected from the sensor is transmitted to the ASIC chip through the sensor interface, and the ASIC chip modulates the collected data into an uplink signal and sends it to LEO satellite through the tuner.
