Mobile Positioning Technology

Nikos Deligiannis, Spiros Louvros, Stavros Kotsopoulos · IGI Global eBooks · 2009

A radio mobile-position system operates by measuring, processing, and storing physical quantities related to radio signals travelling between a mobile terminal and a set of transceivers, for example, satellites or Base Stations (BSs). Positioning techniques in cellular networks are of great importance for supporting emerging services that require a sufficient, precise estimation of the position of the mobile terminal (MT) associated with a number of given base stations. The ability to support position location within wireless networks provides network operators with valuable services, as well as users with a host of new applications. This includes navigation, location-based services, network management, and security applications. Nowadays in GSM networks, there is no specific algorithm included in the software to locate subscribers. The only possibility to locate a subscriber is accomplished by using GPS technology or special firmware. An innovative development should be the design and implementation of certain location positioning techniques, as Time of Arrival (ToA) and Angle of Arrival (AoA), over the existing GSM network. Although there are already next generation networks in use nowadays (UMTS, GPRS, WLAN), and there also is extensive research towards the fourth generation cellular networks, GSM seems to be the most popular network so far. GPRS network is a data network over GSM platform and it exists only with GSM architecture. The reason is that GPRS uses the GSM air interface (Radio Network Part) and it only diverts in the core network where it transmits the data packets towards a different switch. UMTS, on the other hand, is a unique network supporting cellular and voice-data applications, and is the evolution of GSM towards IP applications. Although it could be implemented separately from GSM, most of the operators preferred to implement it in a GSM convergence mode towards the core network for eliminating the investment. As a result, in most countries GSM is the major network with full geographical coverage and network location positioning techniques are most implemented in a network environment with a satisfactory number of Base Stations.

Positioning Technology (GPS)

David A. Tyler · ASSA, CSSA and SSSA · 1993

The global positioning system (GPS) was designed primarily as a military navigation system intended to provide 24-h, all weather, real-time positioning to within tens of meters worldwide. This chapter describes the basic properties of the system and explains the principle ways in which it is used, particularly in the context of agriculture. The former USSR has implemented a navigation system call GLONASS which is very similar to the GPS. GLONASS consists of 24 satellites in three orbital planes at an altitude of 19,100 km with an 11.25-h orbit. The first commercial GPS receiver designed for civilian use in the early 1980s, the Macrometer, was designed to ignore the coded signal completely andonly use the carrier phase. Pseudo ranges from four satellite positions will allow the computation of the receiver position, X, Y, and Z in an earth-centered Cartesian coordinate system and the clock offset.

Geomagnetic positioning and navigation technology

Yirui Cui, Shihang Liang, Qing Ma et al. · 2026

This paper designs and develops a geomagnetic positioning and navigation device, which is a passive autonomous positioning technology. Based on the Earth's magnetic field as a vector field and a natural coordinate system, it relies on geomagnetic information to form a geomagnetic database corresponding to geographic coordinates. Using a three-axis fluxgate orthogonal structure, three sensors measure magnetic field components. Combined with quantum sensing and AI algorithms, and integrated with inertial and satellite navigation, the system constructs a 3D model from the geomagnetic database to provide guidance direction, target direction, and navigation object position information, achieving precise positioning in multiple fields. The system's measurement deviation is only 0.004%, with high precision (0.15%) and other features.

Patient Positioning and Surgical Technology

Ben Creavin, Michael E. Kelly, Desmond C. Winter · 2021

Patient positioning is extremely important as it impacts on operative access and anesthetic needs, and can reduce potential complications for the patient. Ultimate responsibility of patient position lies with the principal operator, although all surgical staff are responsible for ensuring that the position and safety of the patient is maintained throughout the procedure. Traditional methods of suture ligating a vessel are challenging in deep pelvic surgery and have been aided by the use of energy devices, clips, and stapling devices. Setup of operating room is an important component in any surgical procedure and should be discussed with all members of the surgical team prior to commencing the operation. Operating room setup is more complicated for robotic surgery and requires complex and expensive equipment. A modified Lloyd-Davies approach is the most common position encountered in pelvic exenterative surgery. Sacrectomy is usually performed in the jackknife prone position following the completion of the abdominal and perineal phase.

Indoor positioning: technology comparison analysis

Marina Md Din, Norziana Jamil, Jacentha Maniam et al. · International Journal of Engineering & Technology · 2018

A system that allows users to find and track a specific position is known as positioning system. Global Positioning System (GPS) is one of top known position tracking system that commonly used to find position and location of object outdoor. Tracking an object indoor using GPS is not highly recommended because the signals transmitted through a satellite to a device indoor gets blocked and resulted in weak signals. Thus, an indoor positioning system (IPS) that tracks and positions object indoor has been implemented to overcome the issues of signals multipath that resulted from GPS. The aim of this paper is to provide up to date indoor positioning technologies and compares the technologies according to its technical perspectives.

Indoor positioning using NFC technology

Viljem Dernikovič · 2014

In this diploma thesis an example of the indoor positioning system using NFC technology is presented. The indoor signal of satellites, such as GPS, is not visible to the navigational devices, so the positioning there is not possible. The thesis covers the development of several applications including Android application for smartphones. The smartphone user reads ID from NFC label and gets his current position and the list of all possible destinations from the server. User can then select one destination and can receive the shortest path from the current position to the destination from the server. Mobile application navigates him between NFC labels on this shortest path until the destination is reached. The thesis also covers some mathematical and physical problems connected with the topic and possible solutions. In the last chapter the statistical analysis that can help find strong magnetic field anomalies is presented.

Positioning creative design in Technology?

Alison McGlashan · ResearchSpace (University of Auckland) · 2010

In an effort to enhance the education of young designers in New Zealand this paper looks at the key role of design thinking and methodology in Technology education. It suggests that the inclusion of ‘designerly thinking’ (Cross 2001) will shift the current emphasis in the learning area of Technology in the New Zealand curriculum from an information gathering, declarative and procedural knowledge viewpoint towards a state of balance through the development of creative, innovative and curious minds. In comparison, innovation developed by curious minds through a “wealth of design experiences, a way of seeing and perceptive reflection-in-action,” Mc Glashan (2010) is at the core of creative design practice.
