As part of ongoing research to help prevent and mitigate disruptions to computer networks on the Internet, researchers at Sandia National Laboratories in California have turned their attention to smartphones and other hand-held computing devices.
Search For The Tool
Sandia cyber researchers linked together 300,000 virtual hand-held computing devices running the Android operating system so they can study large networks of smartphones and find ways to make them more reliable and secure. Android dominates the smartphone industry and runs on a range of computing gadgets.
Falcon Hypersonic Technology Vehicle 2 (HTV-2), the fastest aircraft ever built is designed to fly anywhere in the world in less than 60 minutes, crashed into the Pacific Ocean, although officials said they were able to gather “unique data” that will guide the development effort.
Flight one achieved many firsts: Deployed largest number of sea, land, air and space data collection assets in support of hypersonic flight test Maintained Global Positioning System (GPS) signals while traveling 3.6 miles per second; Validated two-way communication with the vehicle; Verified effective use of the Reaction Control System (RCS).
Launched from outer space
Three technical challenges exist within this HTV-2 flight regime. They are categorized as aerodynamic; aerothermal; and guidance, navigation and control. And each phase of flight introduces unique obstacles within these areas.
DARPA’s Falcon Hypersonic Technology Vehicle 2 (HTV-2) program is a multiyear research and development effort to increase the technical knowledge base and advance critical technologies to make long-duration hypersonic flight a reality.Mastery of three key technical challenges stands between the DoD and long-duration hypersonic flight: Aerodynamics; Aerothermal effects; and critical guidance, navigation and control.
Historic first launch puts HTV-2 into suborbital flight.

Crime has been on the rise and it’s important to keep a track on your children, lest anything happens to them. SatGuide has launched Child Phone with Tracker in India to help you to keep a watch on your children when they are away.
Child Phone is a GPS receiver, which when activated helps parents keep a check on their children. In any sort of an emergency, a kid can contact his/her parents by pressing the SOS button in the middle. This sends out SMS messages to preconfigured numbers so that you take appropriate action. . This gadget works two ways it can track using the powerful GPS and when GPS signal is unavailable it can switch to GSM Cell Tower triangulation technologies.
Child Phone protection
A normal mobile phone for your child may be another option but it has its own disadvantages. The child may play around with the phone which may drain off the battery or can even accidentally switch it off, not to mention calling unwanted numbers. As far as GPS is concerned parents would in no way get a costly phone with all those features for their child.
Parents can build a “Geo Fence” which is a virtual fence like your residential area or the school and parents get a notification if their child has left that area. They can also call their kids discretely during an emergency and listen to what’s going around in their kid’s environment. Child Phone is small and has no display so it’s comfortable for kids to carry it and they don’t get distracted by it. Following are some other ways of using Child Phone:
- Can be used almost instantaneously. GPS integrated, fast Time To First Fix (TTFF) to GPS satellites,
- Parent can locate the kid at all times discretely on a map through a web login without disturbing the child.
- You can also schedule, your child phone tracking at continuous & periodic times of your choice and get SMS & email alerts.
- Fake power off feature, when configured, the device works even when the device is switched off.
- Lost mobile feature, if the SIM is changed in this mobile, you would get an alert giving the details of the changed mobile number.
Child Phone Key Features
* Easy to use with a compact design
* Supports GSM Tri-Band frequency
* GPS through SatTracx service
* Geo Fence security
* Works indoors and even when GPS is unavailable
* Locate using Web or by calling the phone.
