The characteristics and application of mobile satellite services

Its scope is commonly measured in feet 2.

Satellite communications : mobile and fixed services

Through telecommunications, this value may be: Through this reverse engineering, the non-subscribing provider may be able to interpret some user characteristics from non-encrypted headers.

Apart from those in sun-synchronous orbitfew satellites are launched into retrograde orbit because the quantity of fuel required to launch them is much greater than for a prograde orbit. To ensure orderly communication over a network, all the nodes in the network must follow a set of rules called protocols.

Electronic communication can take place in one-way or two-way transmission mode. Overcoming geographical dispersion - Telecommunications enable an organization with geographically remote sites to function, to a degree, as though these sites were a single unit.

Also, techniques, systems, subsystems and methods described and illustrated in the various embodiments as discrete or separate may be combined or integrated with other systems, modules, techniques, or methods without departing from the scope of the present disclosure. This is mostly used in the aircraft applications as it provides safety through the radio communication to control flight locations and the movements of light and the positions of aircraft on land as well.

The computer implemented method of claim 17wherein the content is a selected advertisement transmitted to the mobile device based on the user characteristics and the mobile device is one of a portable computer, a tablet computer, and a laptop computer. The header includes user characteristics, such as the geographic location, demographics, and usage information for the mobile device and the mobile device's user.

This article mainly focuses on the mobile satellite services and their types as mentioned below. The processing of a given application is split up among a number of clients - serving individual users - and one or more servers - providing access to databases and doing most of the computing.

Antenna Radome for SATCOM User Mobile Terminals

Fast packet switching that checks a packet for errors only at the entry and exit nodes of the telecommunications network, thus reducing transmission delay.

The cell tower or wireless network access node is coupled to the telecommunication networksuch as the Internet.

Communication medium diagram

In boxa content to provide to the mobile device is determined based on the user characteristics in the header For example, the network service server may change encryption keys periodically in association with information service subscriptions.

Gateways such as routers and bridges help solve the problem. Orbital Altitudes of several significant satellites of earth. An orbit around the planet Marssuch as by moons or artificial satellites. The RAM is used to store volatile data and perhaps to store instructions. To take advantage of this, two fast packet-switching technologies are being introduced: Interconnection between two networks of the same type is accomplished by a relatively simple bridge, implemented in hardware and software.

Satellite Electronic Communication System for Mobile Phones

With such a network connection, it is contemplated that the processor might receive information from the network, or might output information to the network in the course of performing the above-described method steps.

Communications from the mobile device to the provider server use a header The present examples are to be considered as illustrative and not restrictive, and the intention is not to be limited to the details given herein.

The power and bandwidth of these satellites depend on the specifications like complexity, size and cost. The process of communication can be of different forms like verbal, non verbal, print and electronic.

Advertisements may be an advertisement displayed with requested content, such as a banner advertisement that is inserted in content that the mobile device requested from a news organization web page.

This service can be used in applications like ships, airlines and TV broadcasting systems. All of the signalling between mobile terminals, fill-in base stations and satellites will occur in the sections of the L-band that have already been assigned to MSS service. Combination digital satellite and off-air antenna.

Alternatively, the network service server can provide the user characteristics to the mobile device, such that the mobile device can supply the user characteristics for the header when communicating with the provider.

The mobile device may determine its position based on the different signals received from different satellites. The DSP or some other form of controller or central processing unit operates to control the various components of the mobile device in accordance with embedded software or firmware stored in the memory Packet switching is of particular importance for data communication owing to its speed and its superior utilization of communication links when handling Abursty, intermittent, traffic.

Centric classifications[ edit ] Geocentric orbit: Therefore, X band provides a good compromise between terminal size and data rates while maintaining resilience to rain fade. An orbit around the Sun. mobile-satellite service) in the frequency band 5 MHz .

RESOLUTION ( Frequency sharing in the bands 1 MHz and 1 MHz between the mobile-satellite service and the radio.

Mobile and Satellite Communications MSc Overview; Programme details; Entry requirements; Fees and funding; Technical characteristics of the pathway.

The course material is complemented by study in areas such as mobile applications and web services, mobile app software development, RF design, internet of things, and network management. Where a terrestrial mobile service is well established, such as in Western Europe, Satellite mobile services can play a more dominant role "Iridium a low earth orbit mobile satellite system", Application of Motorola Satellite Communications inc, before the FCC, Washington, D.C., December Satellite interconnects the nodes and provides some better advantages in application than the traditional communication systems such as combine massive data connections, mobile communication and direct connection for last-mile users, television and other broadcasting for public [1].
