Currently, Communication Technology have an important role in our daily life. The technology of Internet of Things (IoTs), which is most likely will be deployed in conjunction with satellite technology. The currently developed technologies are based on satellite constellations in low Earth orbit, including CubeSat and nanosatellite constellations. This paper presents the results of a theoretical investigation of the feasibility of successful communication between a LoRa in a ground station and a LoRa in the satellite, including the Doppler effect that an IoT device may experience. Several sets of essential transmission parameters were considered, and their successful or unsuccessful outcomes were simulated. In addition, a laboratory testing was conducted to find out whether different transmission frequencies would affect the transmission quality considerably or not. It was found that, in principles, a few sets of essential transmission parameters would provide feasible communication between a LoRa on the ground and a LoRa in a satellite. In addition, the laboratory testing showed that different frequencies in the range of 923–925 MHz did not affect the transmission quality differently. The theoretical and experimentally acquired parameter values reported in this paper may directly benefit developers of new applications of LoRa and IoTs satellite in their effort to design an effective communication scheme for their system.

The rendezvous mission is one of the most useful and interesting in aerospace industry. Working together of multiple Unmanned Aerial Vehicles (UAV)s with limited space can cause the damage to UAVs. This research presents Unmanned Aerial Vehicle (UAV) rendezvous method that can approach UAV to another UAV with minimum displacement between them while they are moving. This rendezvous method is guided by Line-of-Sight (LOS) guidance law. The mission is guiding the UAV to join the route of another UAV to the end of mission with minimum displacement and without collision between them. Aerial Information and Robotics Simulation or AirSim which is working on Unreal Engine 4 software is presented. The positioning of UAVs is provided by Global Positioning System (GPS) sensor on both UAVs.

Low gravity is one of the most challenging aspects of robot space exploration. Due to changing gravitational force, the locomotion performance of a legged robot tends to reduce when the gravity decreases. Recently, quadrupedal robots have increasingly been promoted for space exploration. Most existing studies have mainly developed robot locomotion with an erect posture and focused on the use of leg functionality. However so far, the robot locomotion with a sprawling posture and a flexible spine has not been fully investigated. According to this research gap, we present here the sprawling posture robot with a flexible spine inspired by geckos for low-gravity locomotion enhancement. The gecko-inspired robot is constructed with the 3-DOF spine and the 4-DOF legs. The movement of the robot is controlled by a central pattern generator (CPG). The experiments were performed in a physical simulation under the gravities of Earth, Mar, and the Moon. The experimental results show that, due to the lateral bending movement of the flexible spine with a C-Shaped standing wave pattern, the locomotion speed of the robot is increased by 100%, compared to the one with a traditional fixed spine under each gravity. Based on these results, a sprawling-type quadruped robot with a flexible spine will shed a new light for the future study of robot space exploration under low-gravity conditions.

Uncontrolled fire ground to ground rockets produce high impact point dispersion due to various sources of error and environmental uncertainties. To increase a high single-shot hit probability, the rocket systems must equip with an on-board control mechanism. This paper investigates the use of lateral pulse jet control to reduce the dispersion of fire rockets. The numerical simulation of rocket trajectory is used to predict the impact point from an arbitrary state. The magnitude and direction of pulse jet thrust are based on the difference between the predicted impact point and target location. A comparison of dispersion for the uncontrolled and controlled impact points is proceeded through a Monte-Carlo simulation. It is shown that the dispersion radius, which is defined as the radius of circle centered at the mean impact point and containing 50% of the impact points, for the controlled case is noticeably smaller than the uncontrolled case.

With emerging technologies and extended reality (XR) technology on the rise in logistics education programs, we evaluated the perceptions of Thai undergraduate students and faculty members on XR learning experiences using an XR Literacy Framework. The XR Literacy Framework was adapted from NMC Horizon Project’s digital literacy framework and informed by the research work of Pehlivanis, Papagianni, and Styliadi (2004), and DHL’s Key Developments and Implications (2019).

Questions focused on perspectives on XR usage in logistics management undergraduate programs in Ladkrabang, Bangkok, Thailand in the key areas of training levels and confidence in application of XR technology. All research constructs were measured using multiple-item 5-point Likert scales and target respondents were evaluated in terms of XR for logistics management familiarity. The data was collected from a judgment sample of respondents on a voluntary basis and analyzed with SPSS software.

A single t-test survey was performed to assess if there was a statistically significant difference between the sample qualified and the overall population. In both cases of training and confidence in application of XR technology, levels were deemed to be low.

Following responses on identified critical points, we recommend further study on increasing XR training in undergraduate logistics education programs and building confidence in practical application of XR technology.
