This article reviews that from the Cold War to Voyager, the work of Robert Goddard has received much recognition. Independently, Goddard started conceiving and designing a variety of air and space vehicles, and analyzing methods for propulsion and control. In 1903, Wilbur and Orville Wright had achieved powered flight with the three-axis control they had invented, but the flying machine was extremely difficult to manage. In 1907, while he was still an undergraduate, Goddard studied the dynamics of the Wright Flyer, and designed a gyroscope-based stabilizer for automatic control. His attempts to procure government funding were rejected by a United States military that did not recognize any value of rockets beyond the possibility of assistance at takeoff for aircraft. Rockets increasingly are supporting the marvels of our post-Cold War information revolution. The satellite-based Global Positioning System has brought the most sophisticated navigation system into the personal automobile. Within the century, Robert Goddard’s vision and life’s work begat far more than he could have imagined.

The increasing use of vehicles, especially motorbikes, has the potential to increase motor vehicle theft cases. The increase in motorcycle theft cases can occur due to the weakness of the owner in installing a motorcycle security system, so that it has the potential to experience losses due to theft. An indication of the problem is how to develop an application that can be used to carry out tracking that can display the position of the vehicle with integrated maps and vehicle control remotely in the event of a vehicle theft. The development of Internet of Things (IoT) technology as well as information and communication technology can now be used to develop an application for wireless vehicle monitoring and control. So that it can make it easier for vehicle owners to track and control the vehicle to minimize vehicle loss. In this study using MIT App Inventor as an application development platform and using ThingSpeak as an IoT database server. Furthermore, the application will be integrated with the Tracking Device device consisting of a microcontroller, Global Positioning System (GPS) module, and a DC relay installed on the vehicle, utilizing an internet connection as a link between the application and the tracking device. The result is that vehicle position data can be displayed through a mobile application with map visualization integrated with google maps and the user can turn off or turn on the vehicle through the application with the farthest distance that has been successfully tested of 141 km. The time for the tracking device to respond to commands from the application varies from 5 to 20 seconds depending on the strength of the internet connection used.

ABSTRACT The U.S. Navy's Supervisor of Salvage (SUPSALV) Response Asset Tracking System (RATS) was developed to provide enhanced safety and logistics support, improve worldwide contingency planning capabilities, and increase operational responsiveness through automated tracking of oil spill containment and recovery equipment. RATS's worldwide tracking capability is accomplished by combining Global Positioning System (GPS) technology with VHF and INMARSAT-C transmission links. The system allows the equipment's position to be automatically overlaid on digitized mapping systems and nautical charts. The application of GPS-based RATS technology to oil spill containment and recovery scenarios greatly enhances “command and control” and operational effectiveness.

Abstrak Pentingnya untuk mempertahankan kelangsungan hidup masa depan perusahaan, maka diperlukan perencanaan yang jelas dan pengendalian yang efektif terhadap biaya pengeluaran pada kegiatan operasionalnya. PT SLI merupakan perusahaan yang bergerak dibidang penyedia jasa tracking system atau Global Positioning System (GPS). Pada kegiatan tersebut tentunya dikenakan biaya operasional, karena pada setiap kegiatan kerja terdapat biaya-biaya tertentu yang diperlukan dalam menjalankan kegiatan operasi perusahaan. Pentingnya efektivitas pengendalian biaya terhadap biaya operasional yaitu dapat membantu perusahaan dalam menganalisis varians biaya operasional sesungguhnya terjadi, agar pada realisasi biaya yang sebenarnya terjadi tidak mengalami kelebihan dari anggaran yang telah ditentukan sehingga tujuan pada perusahaan dapat tercapai. Metode analisis yang digunakan yaitu dengan metode deskriptif mix methods. Hasil penelitian dari analisis varians biaya operasional di PT SLI, terjadi penyimpangan biaya yang menguntungkan maupun tidak menguntungkan. Tentunya telah dilakukan upaya perbaikan pada pengendalian efektivitas terhadap biaya operasional yang dilakukan perusahaan pada setiap penyimpangan biaya yang terjadi.   Kata Kunci : biaya operasional, efektivitas, pengendalian, analisis varians     Abstract The importance of maintaining the future viability of the company, it is necessary to have a clear plan and effective control of the costs of spending on its operational activities. PT SLI is a company engaged in providing tracking system or Global Positioning System (GPS) services. These activites are of course subject to operational costs, because in each work activity there are certain costs needed to carry out the company’s operations. The importance of cost control effectiveness on operational costs is that it can assist companies in analyzing the variance of operational costs that actually accour, so that the actual cost realization does not experience an axcess of the predetermined budget so that the company’s goals can be achieved. The analytical method used is descriptive mix methods. The results of the analysis of the variance of operational cost at PT SLI, there are profitable and unfavorable cost deviations. Of course, efforts have been made to improve the effectiveness of controlling operational costs by the company on any cost deviations that occur.   Keywords: operational costs, effectiveness, control, analysis of variance

This essay criticizes the continuing use of prisons as the primary means of controlling adjudicated criminal offenders. After conceding that prisons do control, but in ways which violate most of what has been discovered and should be known about how to promote lasting, positive behavior change, the argument is advanced that prisons are obsolete and should be replaced by a satellite surveillance system that would offer a better, less costly method to both monitor and control criminal offenders under conditions with far more potential for successful rehabilitation efforts.

Precision-guided airdrop systems have shown considerable accuracy improvements over more widely used unguided systems through high-quality position, velocity, and time feedback provided by global positioning system (GPS). These systems, like many autonomous vehicles, have become solely dependent on GPS to conduct mission operations. This necessity makes airdrop systems susceptible to GPS blackout in mountainous or urban terrain due to multipathing issues or from signal jamming in active military zones. This work overcomes loss of GPS through an analysis of guidance, navigation and control (GNC) capabilities using a single radio frequency (RF) beacon located at the target. Such a device can be deployed at the target by ground crew on site to retrieve package delivery. Two novel GNC algorithms are presented, which use either range from or direction to a RF beacon. Simulation and experimental flight testing results indicated that beacon-based methods can achieve similar results as GPS-based methods. This technology provides a simple and elegant solution to GPS blackout with best method studied showing only a 21% decrease in landing accuracy in comparison to GPS-based methods.
