Tracking Using GPS Technology

The use of global positioning system (GPS) technology underpins many different methods of tracking. GPS tracking involves the use of a beacon that sends the location of a device to satellites to determine the precise location of the beacon. In recent years, technological improvements have meant that GPS tracking units have become exponentially smaller in size. Whereas early portable beacons such as the Magellan (launched in 1989) were 22 cm in length and around 700 grams in weight, if not larger than television screens, they can now fit into the back of watches and mobile phones (Shoval and Isaacson, 2010). This chapter will explore the development of GPS technology and its application to tourism research, when utilised with portable GPS loggers.

The crucial question that this chapter examines is whether an employer may track employees during work hours using the Global Positioning System (GPS) without violating employees’ right to privacy. This chapter argues that GPS installation in employer-owned mobile phones and computers can coexist harmoniously with employees’ right to privacy when the GPS tracking does not seek to keep track of employee whereabouts but, instead, to optimize a travel route and enhance employee safety by providing the possibility of immediate intervention if necessary, such as when a specified location is needed. If a GPS has been installed in order to assist employees in reaching a destination most efficiently, then this system must be placed solely and exclusively for this purpose, and the employee must retain the right to deactivate it at will.

Precision agriculture is already being used commercially to improve variability management in row crop agriculture. In the same way, understanding how spatial and temporal variability of animal, forage, soil and landscape features affect grazing behavior and forage utilization provides potential to modify pasture management, improve efficiency of utilization, and maximize profits. Recent advances in global positioning system (GPS) technology have allowed the development of lightweight GPS collar receivers suitable for monitoring animal position at 5-min intervals. The GPS data can be imported into a geographic information system (GIS) to assess animal behavior characteristics and pasture utilization. This paper describes application and use of GPS technology on intensively managed beef cattle, and implications for livestock behavior and management research on pasture. Key words: Livestock behavior, electronics, grazing, forage, global positioning system, geographic information system

The purpose of this research is to design an attendance system using Global Positioning System (GPS) technology, as a useful solution. At PT. Cipta Anugrah Musi for the marketing staff to still be able to do attendance without using a fingerprint attendance machine. Based on the results of research and discussion on the marketing employee attendance monitoring system in the form of this android mobile, the following conclusions can be drawn. From the black box testing that has been done, it can be concluded that the employee attendance monitoring system can run well and there are no problems. GPS technology can provide information on where to take employee photos so that it is easy to find out the position of the employee's absence at that time to avoid cheating in attendance.

A user’s position-specific field has been developed using the Global Positioning System (GPS) technology. To determine the position using cellular phones, a device was developed, in which a pedestrian navigation unit carries the GPS. However, GPS cannot specify a position in a subterranean environment or indoors, which is beyond the reach of transmitted signals. In addition, the position-specification precision of GPS, that is, its resolution, is on the order of several meters, which is deemed insufficient for pedestrians. In this study, we proposed and evaluated a technique for locating a user’s 3D position by setting up a marker in the navigation space detected in the image of a cellular phone. By experiment, we verified the effectiveness and accuracy of the proposed method. Additionally, we improved the positional precision because we measured the position distance using numerous markers.

AbstractThe aim of this study was to examine the physical demands imposed on professional soccer players during 11-a-side friendly matches in relation to their playing position, using global positioning system (GPS) technology. One hundred and eleven match performances of a Spanish “La Liga” team during the 2010-11 and 2011-12 pre-seasons were selected for analysis. The activities of the players were monitored using GPS technology with a sampling frequency of 1 Hz. Total distance covered, distance in different speed categories, accelerations, and heart rate responses were analyzed in relation to five different playing positions: central defenders (n=23), full-backs (n=20), central midfielders (n=22), wide midfielders (n=26), and forwards (n=20). Distance covered during a match averaged 10.8 km, with wide and central midfielders covering the greatest total distance. Specifically, wide midfielders covered the greatest distances by very high-intensity running (>19.8 km·h-1) and central midfielders by jogging and running (7.2-19.7 km·h-1). On the other hand, central defenders covered the least total distance and at high intensity, although carried out more (p<0.05-0.01) accelerations than forwards, wide midfielders, and fullbacks. The work rate profile of the players obtained with the GPS was very similar to that obtained with semi-automatic image technologies. However, when comparing results from this study with data available in the literature, important differences were detected in the amount of distance covered by sprinting, which suggests that caution should be taken when comparing data obtained with the GPS with other motion analysis systems, especially regarding high-intensity activities.

Abstract The Department of Mechanical Engineering and the Avionics Engineering Center at Ohio University are developing an electromechanical system for the calibration of an inertial measurement unit (IMU) using global positioning system (GPS) antennas. The GPS antennas and IMU are mounted to a common platform to be oriented in the angular roll, pitch, and yaw motions. Vertical motion is also included to test the systems in a vibrational manner. A four-dof system based on the parallel Carpal Wrist is under development for this task. High-accuracy positioning is not required from the platform since the GPS technology provides absolute positioning for the IMU calibration process.
