...safety in 1999. Today many civilian GPS users have come to conflicting arguments as to whether or not GPS is here to help or hinder us. Between foreign nations such as China working to have successfully launched 35 satellites by 2020, and Superior court trials arguing violation of privacy… Has GPS found a competitor? What GPS does for us GPS is used daily for coordinating airliners (NextGen), city transit, package delivery, keeping track of our children as well as felons under adult supervision by ankle monitor. In many search and rescue situations, natural disaster and criminal monitoring or investigating, time is as critical as life or death. On August 6, Fox News published a story on Precise Innovations kidsport GPS band developed by a concerned parent Brian Sullivan. A device that will give parents there child’s direct location to a partner app on the parent’s cellphone within 10 feet of the child. This device has a panic button to notify the parent if the child wonders outside the “geo-fence” (the perimeter the parent sets). In 2005 GPS was used with GIS (Geographic Information Systems) by giving precise location of landmarks, streets, and buildings. Precision agriculture or site-specific farming has been made possible by the use of GPS, GIS and remote sensing to locate and map field boundaries, roads, irrigation systems and problems such as weeds or disease soil. What GPS has done to us Now that I’ve given some great examples of what GPS does to help the...

...SSG Riemann, SSG Carerras & SGT Horner SFC Hopkins 13T ALC 11 October 2012 Equipments and Tactics from the World Wars and Today The Field Artillery is and always has been the King of Battle. Technology and tactic have been refined over the years based on lessons learned from the past. During the World Wars the implementation of new equipment and tactics helped shape the field artillery of today. However, some of the same equipment and tactics are still being used today. Warfare had changed in the years leading up to the United States involvement in WW1. A lot of the fighting went back into the trenches. This in return promoted the use of small munitions such as motors, for closer combat effectiveness. Initially, horses moved many of the smaller artillery pieces like the 3inch motors. They were able to move quicker and in tighter places than a vehicle. However, the ability to keep the horses combat effective became a challenge do to shipping them from so far away. The change from horses to jeeps became a reality. 105mm and 155mm howitzers conducted specific missions and large trucks or even tractors moved them. In 1944 the development of the rocket battalion which provided thirty-six rockets launchers. A single rocket could take out a larger area on its own. This allowed howitzers to be independent. Prior to the rockets they had to bring multiple howitzers together to take out as much real estate as one rocket. However, howitzers were more accurate. The soldiers became...

...332 IEEE SENSORS JOURNAL, VOL. 1, NO. 4, DECEMBER 2001 Inertial Sensor Technology Trends Neil Barbour and George Schmidt, Senior Member, IEEE Abstract—This paper presents an overview of how inertial sensor technology is applied in current applications and how it is expected to be applied in near- and far-term applications. The ongoing trends in inertial sensor technology development are discussed, namely interferometric fiber-optic gyros, micro-mechanical gyros and accelerometers, and micro-optical sensors. Micromechanical sensors and improved fiber-optic gyros are expected to replace many of the current systems using ring laser gyroscopes or mechanical sensors. The successful introduction of the new technologies is primarily driven by cost and cost projections for systems using these new technologies are presented. Externally aiding the inertial navigation system (INS) with the global positioning system (GPS) has opened up the ability to navigate a wide variety of new large-volume applications, such as guided artillery shells. These new applications are driving the need for extremely low-cost, batch-producible sensors. Index Terms—Accelerometer, gyroscope, inertial, MEMS. I. INTRODUCTION LECTROMECHANICAL inertial sensors have generally dominated guidance, navigation, and control applications since the dawn of inertial sensing in the early 1920s [1]–[4]. In recent years, however, new technologies have enabled other kinds of sensors that are challenging and have successfully...

...annoying. It's like living in a house with no doors. Everyone needs privacy in his or her life. I've always heard people refer to the government as "Big Brother". Big brothers are supposed to protect their younger siblings. Is "Big Brother" protecting us? Or just out right being nosey & invading our privacy? In our society today everything we do is being tracked. There's video surveillance everywhere we turn. Every click of a mouse or push of a button on the Internet is being tracked & logged. Almost everything today is GPS enabled. The government can access these records, videos, and locate people from their GPS enabled device without their knowledge. Scott McNealy couldn’t have said it any better “You have zero privacy anyway. Get over it” (Sprenger, 1999, para.1). The evolution of technology has made it easier for Big Brother to watch us. Our privacy against government intrusion is virtually impossible because technology has provided more access than our judicial, legislative and political systems have developed restrictions. After 9/11 The Patriot Act was one of many surveillance laws that made it easier for the government to keep an eye on us. The change in this law gave the government more authority to check any citizen’s Internet usage, obtain bank and credit card information, check emails, and monitor phone calls. The government obtains this information by sending out National Security Letters (NSLs). After the information is obtained and used...

...mobile systems with greater data transfer speed and capacity and 1st generation satellite mobile systems. Evolution to the current generation mobile networks to 3G doesn't necessarily mean seamless upgradation to the existing infrastructure to the 3G. Evolution should also be seen in context of coexistence of the 2G and 3G networks for some time, with users able to roam across the new and the old networks, able to access 3G services wherever 3G coverage is available. As mentioned before, a 3G network can have one of the 3 optional air interfaces supporting one of the two GSM MAP and IS-41 network architectures. This results in a range of choices for the existing networks to evolve/migrate towards 3G. Possible convergence of TDMA and GSM networks with EDGE adds another variable to the overall migration paths. Another variable that adds complexity to this already complex list of options is the time frames involved. By the time some of the 2.5 or 2.75G technologies go to field, we may see the emergence of 3G technologies also. So, a lot of thought regarding the costs involved, and/or the viability of 2.5G technologies like EDGE could be questioned. The same is true about the time frames of the so called "4G". Before I talk about evolution/migration paths of all the existing 2G mobile wireless technologies, let me briefly discuss the 3G network architecture and other technology factors involved in the migration to 3G. 3G Architecture The 3G network will have a layered architecture...

...In Ronald Bailey’s (2013) article “Your Cellphone is Spying on You,” he claims that with the recent evolution of technology the public has had less privacy, due to GPS and tracking systems. While GPS and location systems within cell phones can be viewed as beneficial to the people, it can also be used by third parties to view a person’s location at any given time. Not only can these parties access locations, they also have access to personal information within the cell phone itself. As stated by Sonia Sotomayor, a U.S. Supreme Court Justice, “Awareness that the Government may be watching chills associational and expressive freedoms” (para. 10). This means that with the knowledge that the government may be watching at any given time, the people...

...As technology advances throughout the years, American’s privacy slowly corrodes over time. It is almost impossible to not be tracked in the United States since there are so many technologies that invades American civilian’s privacy, like cellphone’s applications and satellites. Surely near the future, there will be a device that will allow anyone who uses it to be anonymous from all technologies. For now, this device can be called Personal Anonymous Device (or PAD). PAD will bring American back their privacy when used, but at the price that it could be potentially used for crimes. It is important to mention on how American’s privacy is being threaten over the past few years. According to http://www.pewresearch.org/fact-tank/2017/01/12/evolution-of-technology/, as of 2016, 77% of Americans own a smartphone and it is growing steadily yearly. Smartphones usually has many features, in which almost all smart phones have a GPS system, which...

...two very important, but competing, interests: the public’s interest in preserving its privacy rights and expectations, and the government’s interest in its ability to investigate and subsequently prosecute criminals. However, the methods and rules previously established have yet to be fully tested in our ever-evolving world of technological advances. This raises the question of whether certain well-established rules, specifically the Third-Party Doctrine, are ill-suited to address modern issues. As it has been applied since 1979, and in the absence of reevaluation, the Third-Party Doctrine is likely to impede, severely, on the privacies guaranteed by the Fourth Amendment. In order to fully understand the gravity of this predicament, the evolution of Fourth Amendment analysis must also be understood. In 1949, the Court established that the Fourth Amendment applies to the states through the Fourteenth Amendment. However, it was not until 1961 that the Court held that the exclusionary rule also applied to the states. And, in 1984, the Court explained that because the exclusionary rule was a judicially created remedy to deter Fourth Amendment violations the costs of excluding inherently trustworthy evidence...

...The 4G network was chosen for this topic because of the impact it has on wireless communications. I think the most important tool a person can carry these days is the cell phone. My essay attempts to show how critical the 4G networks is to our beloved cell phone and other wireless devices. Abstract The 4G Networks In telecommunications, 4G is the fourth generation of mobile communication technology standards. It is a successor of the third generation (3G) standard. While all 4G service is called “4G,” the underlying technology is not the same. Sprint, for example, uses WiMax technology for its 4G network, while Verizon Wireless uses a technology called Long Term Evolution, or LTE. No matter what technology is behind it, 4G wireless is designed to deliver speed. The Origin and Definition of the Term The fourth generation is a promising generation of the mobile communications that is characterized by a high data rate and high-quality voice communications. Advanced technologies that make data communications at a rate, exceeding 100 megabits per second for mobile subscribers, belong to the fourth generation. As a rule, the specifications of any generation of the mobile communications refer to the...

...Generation (2G) technology was launched in the year 1991 in Finland. It is based on the technology known as global system for mobile communication or in short we can say GSM. This technology enabled various networks to provide services like text messages, picture messages and MMS. In this technology all text messages are digitally encrypted due to which only the intended receiver receives message. These digital signals consume less battery power, so it helps in saving the battery of mobiles. The technologies used in 2G are either TDMA (Time Division Multiple Access) which divides signal into different time slots or CDMA (Code Division Multiple Access) which allocates a special code to each user so as to communicate over a multiplex physical channel. 3G technology generally refers to the standard of accessibility and speed of mobile devices. It was first used in Japan in the year 2001. The standards of the technology were set by the International Telecommunication Union (ITU). This technology enables use of various services like GPS (Global Positioning System), mobile television and video conferencing. It not only enables them to be used worldwide, but also provides with better bandwidth and increased speed. This technology is much more flexible as it can support 5 major radio technologies that operate under CDMA, TDMA and FDMA. CDMA accounts for IMT-DS (direct speed), IMT-MC (multi carrier). TDMA holds for IMT-TC (time code), IMT-SC (single carrier). This technology is also...
