March 12, 2024 A good night’s sleep makes everything better. Sleep is a vital time of restoration and rejuvenation. It is only when you are asleep that your body can reach the peak of its recovery powers. Unless you’ve been sleeping under a rock, this is old news. It is hard to miss the tide of interviews and articles from sleep experts, influencers and health professionals praising the benefits of a good night’s sleep. Sleep […]

Figure 1: Scientific observations with GNSS radio occultation (GNSS-RO), GNSS grazing-angle reflectometry (GNSS-GR) and GNSS reflectometry (GNSS-R) techniques from low-Earth orbit (LEO). (Figure provided by the author) Global navigation satellite systems (GNSS) for peaceful uses are facing a hard reality due to increasing regional conflicts in recent years. As a dual-use technology, GNSS for civil, commercial and scientific applications is vulnerable to both denied/degraded service and flex power operation from GNSS satellites and to jamming […]

Building a solid foundation for any construction requires that the ground be adequately compacted and leveled. Construction workers and contractors operating earthmoving machines know it is nearly impossible to do that by eyesight alone. For a few decades, leveling was accomplished using rotating lasers mounted on tall tripods, which could typically cover a little more than 1,500 ft on a job site and laser receivers mounted on masts on the earth-moving machines. However, these systems […]

Image: Scientific Systems Scientific Systems has released upgrades for ImageNav, an image-based navigation software designed for GPS-denied or compromised environments. With more than a decade of development, ImageNav offers a robust alternative to traditional GPS navigation for military operations, particularly in contested environments where jamming poses a threat to GPS reliability. The demand for such technology has become increasingly critical considering enhancements to electronic warfare capabilities, with instances of GPS signal disruption impacting military assets. […]

Image: BAE Systems BAE Systems has been awarded a contract by Boeing to enhance the U.S. Navy’s MQ-25 unmanned aerial refueling system with a modernized vehicle management system computer (VMSC). This upgrade aims to enhance the computing power of the MQ-25 and address both obsolescence issues and overall aircraft performance for future operations. The MQ-25 — recognized as the Navy’s inaugural operational carrier-based UAV — is primarily tasked with aerial refueling capabilities designed to alleviate […]
