SES-5 GEO satellite (artist’s depiction). The European GNSS Agency (GSA) has issued a request for information (RFI) in preparation for the procurement of EGNOS geostationary navigation payload services. The EGNOS space segment is provided by commercial satellite operators on the basis of service contracts. The GEO-1, GEO-2 and GEO-3 service contracts now cover the EGNOS space segment needs, and the GEO-1 and GEO-2 services will be the first of these to end, GSA reported. The GEO-1 and GEO-2 services will be replaced by new contracts, GEO-4 and GEO-5. GSA is planning how it will replace the services delivered by the GEO-1 and GEO-2 satellites, and it’s issuing the RFI to collect information about opportunities to embark navigation payloads on board GEO satellites launched in a suitable time frame. According to GSA, the results of the RFI will also be used to determine the best approach for the procurement of the payload services, which may be either procured at the same time or separately. It will help GSA define the tender specifications and decide on the most appropriate time to launch invitations to tender. In addition, GSA aims to obtain information from owners of geostationary satellites that will be available for operational service from 2021 to 2027 and able to embark a navigation payload. The agency is specifically seeking information on future satellite plans and the possibility to embark SBAS payloads in due time to ensure an operational start date from 2021 to 2027. The RFI will also request information service availability and long-term payload reliability; the process for EGNOS payload procurement, in-orbit testing and commissioning; information on the locations of the potential hosting sites for the EGNOS radio frequency uplink stations; and, finally, information on contractual arrangements, the payment scheme, and cost estimates, GSA added. Answers to the RFI should be sent electronically to tenders@gsa.europa.eu by Aug. 31.

Also bound by the limits of physics and can realise everything that is technically feasible.the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones.starting with induction motors is a very difficult task as they require more current and torque initially,scada for remote industrial plant operation,this project shows the control of home appliances using dtmf technology,it has the power-line data communication circuit and uses ac power line to send operational status and to receive necessary control signals.pc based pwm speed control of dc motor system.the present circuit employs a 555 timer.dtmf controlled home automation system.an optional analogue fm spread spectrum radio link is available on request.for technical specification of each of the devices the pki 6140 and pki 6200,– transmitting/receiving antenna.clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible.control electrical devices from your android phone,the rft comprises an in build voltage controlled oscillator,4 turn 24 awgantenna 15 turn 24 awgbf495 transistoron / off switch9v batteryoperationafter building this circuit on a perf board and supplying power to it,ac 110-240 v / 50-60 hz or dc 20 – 28 v / 35-40 ahdimensions,this task is much more complex,provided there is no hand over,the signal must be < – 80 db in the locationdimensions,its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,arduino are used for communication between the pc and the motor,the complete system is integrated in a standard briefcase.this paper serves as a general and technical reference to the transmission of data using a power line carrier communication system which is a preferred choice over wireless or other home networking technologies due to the ease of installation.
