Innovation in geodesic devices

In geoinformatic systems increases necessity of providing sufficient carrying capacity of transmission distant information.

Among different types of ICT (Information and communications technology), in recent years in information and communications technology industry, there is a huge extension of wireless devices <Wireless> [1], which transfer the dates on distance between points and it don’t requires the electrical guide conductor. The most well- known technology are Wi-Fi, Bluetooth, WiMAX, each of them has some peculiarities which determine its scope use. For a fareness of data transfering they share on: WLAN – Wireless Local Area Networks, WMAN – Wireless Metropolitan Area Networks, WPAN – Wireless Personal Area Networks, WWAN – Wireless Wide Area Network [2].

The pupose of investigetion is searching software information technology and items on them, which will be able to secure automatic calculation of integrated measurements, automatic detection of mistakes and guarantee fast wireless transfer dates on bearers.

There are main types of wireless communication:

1) DCE – transfer – stable wireless communication, when the interact nodes constantly are in boundary visible short territory.

2) Satellite system – receives radio signals from ground stations and transfer signals back on ground stations in boundary of straight visibility satellites.

3) Laser communication system – durable resonance chamber which work on fundamental mode with minimal diffraction bereavement.

4) Mobile communication – wireless telecommunication system which consist of a network of ground receiving and transmitting base stations and mobile communication center.

5) WiMAX (Worldwide Interoperability for Microwave Access) – standard of wireless connection, which secure fast band communication in long distance, comparatively with cable connection very fast.

6) Wi-Fi (Wireless Fidelity) – wireless technology connection and access to Internet with special points of access. Speed of reception transfer radio signals to form 11–300 Mbit/s.

7) MMDS (Multichannel Multipoint Distribution System) – wireless technology which is used for access to Internet, IP-telephony, transfer dates, organization main radio channel for connection ATS in distant settlement.

8) Bluetooth- wireless technology of transfering dates in short distance no more than of 10 meters with speed before 1 Mbit/s.

9) Li-Fi (Light Fidelity) – wireless technology of transfering dates and fast connection to network in any part of the world with special light diodes [1].

In modern geodesic devices it is used flash card or wire connection with electronic carrier. In some measure such method of transfering dates is trustworthy, as information and dimensions is always near operator or give possibility to transfer dates on processing. However such kinds of transfering dates increase time their processing and speed of making documentation. To transfer dates in geodesic devices it is possible using of connection by Bluetooth and Li-Fi. Each other types of connection have their own benefits and drawbacks.

Bluetooth connection possible to use for device and electronic carrier by using realize surveying. It is give possibility for invariable wireless and uninterrupted connection, what will allow conduct survey for operator don’t interact with device. Electronic addition, can interact with device guided by already fixed parameters, which are incorporated in the annex. Li-Fi technology realizes dates transfering and connection with device and carrier by special LEDs. This technology becoming popular and don’t have high coefficient of popularity. Speed of transfering dates allow regularly and constant supporting connection and stream of information from operator, which conduct survey in field condition to office for processing information. Technology combines three colors of light: blue, red and green in – white. Transfering realizes in principle of Boolean algebra. Coding realize by intensity of flickering lamp, when lamp is switched on – 1, when switched off – 0. This technology can decide the problem with keeping custody information and also diminish costs for manufacture. Among advantages of this technology are: abundant functionary possibility, low price, fast transfer dates, energy efficiency, environmental friendliness and economic use. Drawbacks: slow technology development, straight line apparition between transmitter and receiver [2].

Conclusion. Current technology of wireless transfering dates allow economize outlay of making geodesic devices and secure uninterrupted and invariable transfer dates. To take into consideration possibility it may be substitute using flash cart and diminish form device, which in turn influence on weight and outlay on manufacturing device.
