“…Besides these monitored variables, it is often necessary for gateways to monitor the location of the sensor itself [2], especially if it is integrated into a mobile object or tag, for example, if this latter feature is moving inside an indoor environment. The task of localizing a mobile sensor could be challenging for the LoRa working scheme, as this type of communication was not originally optimized for such an application [3], especially if the localization is required to be of high accuracy or expected to accommodate both indoor and outdoor scenarios. In contrast, the main advantage of LoRa communication in LoRaWAN networks is that the sensing information can be transmitted along long ranges in the order of kilometers, typically ranging from 5 km in urban areas up to 15 km in remote areas, from the sensor to the gateways [4,5].…”

Long-Range Wide-Area Networks (LoRaWAN) allow the transmission of data via radio link from sensors, which are potentially isolated or difficult to access, to gateways and servers that are connected to cellular networks for data processing, exchange, or relay, with low transmission power. This concept employs Long-Range (LoRa) modulation and has led to the emergence of many applications for the monitoring and tracking of objects. However, due to its characteristic of a low data rate for low-power communication, the transmission of information with LoRa technology is not suitable for the fast real-time monitoring of data. Additionally, due to its narrow bandwidth, an attempt to perform localization through the LoRa modulation technique will result in very limited accuracy because of its inability to resolve multipath problems. Thus, in this paper, we propose a multi-standard Ultra-Wide Bandwidth (UWB) and LoRa end-device that is capable of measuring location with high accuracy using UWB technology and then transmitting the location information through LoRa method to gateways and the Internet of Things Network. The results of measurements in indoor and outdoor scenarios show a UWB localization accuracy that is of sub-meter level, being between 10 and 33 cm, and a UWB range of 124 m in Line-of-Sight (LOS) and 55 m in Non-Line-of-Sight (NLOS) applications, respectively.

“…Location systems: IoT-based location systems can help track and guide human explorers, as well as locate astronauts, equipment, or materials. These devices can be attached to astronauts or equipment and located using radio triangulation techniques [64], with connectivity protocols like LoRa [65], Bluetooth Low Energy (BLE), or Wi-Fi [66]. • Aerospace medicine: This refers to integrating sensors into astronauts' clothing, monitoring their vital signs during missions to Mars [67].…”

This study outlines a technical framework for Internet of Things (IoT) communications on Mars, leveraging Long Range (LoRa) technology to connect Martian surface sensors and orbiting satellites. The designed architecture adapts terrestrial satellite constellation models to Martian environments and the specific needs of interplanetary communication with Earth. It incorporates multiple layers, including Martian IoT nodes, satellite linkage, constellation configuration, and Earth communication, emphasizing potential Martian IoT applications. The analysis covers four critical feasibility aspects: the maximum communication range between surface IoT nodes and orbiting satellites, the satellite constellation’s message processing capacity to determine IoT node volume support, the communication frequency and visibility of IoT nodes based on the satellite constellation arrangement, and the interplanetary data transmission capabilities of LoRa-based IoT devices. The findings affirm LoRa’s suitability for Martian IoT communication, demonstrating extensive coverage, sufficient satellite processing capacity for anticipated IoT node volumes, and effective data transmission in challenging interplanetary conditions. This establishes the framework’s viability for advancing Mars exploration and IoT in space exploration contexts.
