The axial lead 3.6x9mm 777 series fuse from Littelfuse is designed for overcurrent protection in electronic appliance charger applications. The robust design enables the device to withstand up to 24 hits of 7.5kV ringwave surge; it will open safely on a direct short condition without producing body ruptures and soot phenomenon.

Although the drone revolution in well underway globally in today’s industry, the association between drones and space is largely unreported.Drones may seem like a relatively new phenomenon, but in fact they have been roaming space for the last 60 years in the form of satellites.

As u-blox first came up with the u‑center, the in‑house GNSS analytics software, it thought it was only scratching its own itch. Little did u-blox know that u‑center would eventually become the de facto industry standard for GNSS receiver data analysis on Windows operating systems.Now today, sixteen years later, u‑center continues to pick up new features, driven primarily by the rapid evolution of GNSS receiver hardware.

A research group that includes Motoaki Hara, Senior Researcher at the National Institute of Information and Communications Technology (NICT, President: Hideyuki Tokuda, Ph.D.), developed a simple miniaturised atomic clock system, which does not require a complicated frequency multiplication, as an outcome of a collaboration with Professor Takahito Ono of Tohoku University (President: Susumu Satomi) and Associate Professor Hiroyuki Ito of Tokyo In...

Delivering the right combination of power and performance in GNSS receivers demands an innovative and adaptive approach to signal acquisition, satellite tracking and position decoding. By:Florian Bousquet, Market Development Manager, Product Center Positioning, u-blox.

GateHouse Telecomhas published five trends it sees as the focus of the satellite communications industry in 2018 - with connectivity at the forefront. Other trends span cyber security, the connected aircraft, the increasing use of commercial SmallSats and easier terminal development processes enabled by core modules and off-air test tools.

Supplier of advanced semiconductor solutions, Renesas Electronics, has announced what it claims to be the space industry’s first radiation-hardened, low side Gallium Nitride (GaN) field effect transistor (FET) driver and GaN FETs that enable primary and secondary DC/DC converter power supplies in launch vehicles and satellites, as well as downhole drilling and high reliability industrial applications.

We have lived in a generation of 'one and done' spacecraft, up until now.Barring a few notable exceptions, spacecraft launch alone, operate alone and are decommissioned alone. In an average year, several billion dollars’ worth of satellitesthat could be refueled or repairedare retired because there is no way to service them in space.

Based upon satellites, Presidential and National Voice Conferencing (PNVC) is a second-generation follow-on communications capability with roots in the Milstar Survivable Emergency Conferencing Network (SECN).Ultimate responsibility for all aspects of the programme reside within the FAB-T Terminal Program Office and, with PNVC set to play a critical role in the future of the US nuclear command and control infrastructure, PNVC has received the hig...

The world of agriculture is being quietly transformed by robotic technology. One question to consider is whether tractors will evolve towards full unmanned autonomy?Tractor guidance and autosteer are well-established technologies. In the short to medium terms, both will continue their growth thanks to improvements and cost reductions in RTK GPS technology. Indeed, ID TechEx estimates that around 700,000 tractors equipped with autosteer or tractor...
