The process of receiving AIS signals in the space has a problem of low received power reaching -102.07 dBm. This value comes from the link budget calculation. This paper offers the design and simulation of a CubeSat AIS receiver payload that can operate to receive AIS signals in the orbit at the altitude of 650 km. The AIS receiver is designed to run at 161.975 MHz and 162.025 MHz using Gaussian Minimum Shift Keying (GMSK) modulation method. In this work, the AIS receiver is designed using radio frequency (RF) module Si4362 with operating temperature of -40° to +85° Celsius suitable for the space environment. Here, AIS signal modulation and demodulation methods were simulated using an electronic design automation software for radio frequency components. The simulation results showed the AIS receiver can receive AIS signals under appropriate conditions with link budget calculation. Finally, end-to-end AIS system simulations were carried through real conditions. The results showed the AIS system designed functions at full capacity.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]AIS,CubeSat,GMSK,Low-power,Receiver[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.15866/iremos.v9i6.10958[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
