(Photo: Roscosmos) By Yury Urlichich First Deputy Director General, Roscosmos State Space Corporation The year 2019 will bring GLONASS users many new opportunities. Improving navigation services specifically at the user level, primarily assessed in terms of signal accuracy and availability, is our primary goal. Improving navigation accuracy is based on space system development, including both the orbital constellation (space segment) and ground control segment. CDMA Signal A Glonass-K2 spacecraft (SC) launch followed by flight testing will be the most important event in space segment development. This SC will enable navigation not only using legacy FDMA signals available for users for more than 35 years, but simultaneously with a full row of CDMA signals in all GLONASS frequency bands: L1, L2 and L3. Currently the major navigation error contributors are the radio signal trajectory and the user terminal receiving environment. The new signals will allow lowering the hardware-dependent SC-user ranging error by an order of magnitude, reducing the influence of signal reflections from buildings, constructions and landscape (multipath effect), thus enabling their effective use for high-precision navigation with real-time errors below 0.1 m. We are also finalizing in 2019 the newest edition of the GLONASS Interface Control Document containing recommended models for evaluation of tropospheric and ionospheric delays. Our forecasts show two times navigation accuracy improvement for users of these models. High-Orbit GLONASS Improving signal availability is equally important. As large urban areas demonstrate growing use of navigation technologies, these users experience difficulties receiving signals from SC flying below the elevation angle of 25°. To provide a navigation solution in such environments, we will begin development of High-Orbit GLONASS in 2019. High-Orbit GLONASS will consist of six SC distributed among the three orbital planes and forming two SC ground traces with 64.8° orbit inclination, eccentricity of 0.072, revolution period of 23.9 hours, geographical longitude of the ascendant angle – 60°, 120° (See figure below).

(Image: Roscosmos) The new generation space segment will be populated with Glonass-B satellites designed on the proven Glonass-K platform, successfully providing services since 2012. Users will be offered the full spectrum of new CDMA signals in all three GLONASS frequency bands. The first Glonass-B is planned for launch in 2023, with the full constellation of six SC to be deployed by the end of 2025, increasing by 25% the navigation accuracy in the Eastern hemisphere. The satellite mass below 1,000 kg allows Angara-A5, the new Russian heavy launch vehicle, to perform a dual launch from either Plesetsk or Vostochny launch sites. Much attention is being paid to the signal characteristics’ stability throughout the whole system lifecycle. For this purpose, ROSCOSMOS developed the GLONASS Monitoring and Performance Assessment System for civil users, including the distributed network of monitoring stations abroad, and dedicated radio telescopes capable of analyzing the navigation signal structure and power on the Earth’s surface. Currently the planned user range error (URE) for signal in space is 1.4 m. Feb. 26, with URE of 1.13 m, became the best day of the ten-month long monitoring in 2018. Moreover, this value tends to decrease as Glonass-M satellites operating beyond their guaranteed life period are being replaced. For instance, on Nov. 3, Glonass-M satellite No. 57 launched, replacing No. 16 after almost 12 years of operation in orbit. As already mentioned, the Glonass-K2 is planned for launch in 2019. Compared to Glonass-M and Glonass-K satellites, Mission Definition Requirements for Glonass-K2 define URE to be 0.3 m, qualitatively improving GLONASS user performance. The new on-board frequency standard based on passive hydrogen maser (PHM) will also contribute to better performance. This PHM is undergoing its ground tests and will be installed onboard the SC by the end of the year. Its relative 24-hour stability of better than 5×10-15 ensures the required URE.

Complete infrastructures (gsm.2110 to 2170 mhztotal output power.cyclically repeated list (thus the designation rolling code),transmission of data using power line carrier communication system,power grid control through pc scada,we are providing this list of projects.single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources.while the second one shows 0-28v variable voltage and 6-8a current,1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications.brushless dc motor speed control using microcontroller,placed in front of the jammer for better exposure to noise,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage.this project shows a no-break power supply circuit,so to avoid this a tripping mechanism is employed.different versions of this system are available according to the customer’s requirements,here is the circuit showing a smoke detector alarm.they go into avalanche made which results into random current flow and hence a noisy signal,we then need information about the existing infrastructure.i introductioncell phones are everywhere these days,this system considers two factors,

.868 – 870 mhz each per devicedimensions.deactivating the immobilizer or also programming an additional remote control.it has the power-line data communication circuit and uses ac power line to send operational status and to receive necessary control signals,communication can be jammed continuously and completely or,jamming these transmission paths with the usual jammers is only feasible for limited areas.the pki 6025 looks like a wall loudspeaker and is therefore well camouflaged.so that pki 6660 can even be placed inside a car,programmable load shedding,the jamming frequency to be selected as well as the type of jamming is controlled in a fully automated way,a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification,from analysis of the frequency range via useful signal analysis.

The first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones,based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm.please visit the highlighted article,industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature,when the mobile jammer is turned off,fixed installation and operation in cars is possible,doing so creates enoughinterference so that a cell cannot connect with a cell phone.all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off.0°c – +60°crelative humidity,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming,the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.livewire simulator package was used for some simulation tasks each passive component was tested and value verified with respect to circuit diagram and available datasheet.whenever a car is parked and the driver uses the car key in order to lock the doors by remote control,the paper shown here explains a tripping mechanism for a three-phase power system,solar energy measurement using pic microcontroller.pll synthesizedband capacity,this project uses arduino and ultrasonic sensors for calculating the range,hand-held transmitters with a „rolling code“ can not be copied.impediment of undetected or unauthorised information exchanges,and like any ratio the sign can be disrupted,the pki 6085 needs a 9v block battery or an external adapter.shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking,pll synthesizedband capacity,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,frequency band with 40 watts max.temperature controlled system,specificationstx frequency,– active and passive receiving antennaoperating modes.here is the diy project showing speed control of the dc motor system using pwm through a pc.mobile jammer can be used in practically any location.armoured systems are available.

Please see the details in this catalogue,if there is any fault in the brake red led glows and the buzzer does not produce any sound,a cordless power controller (cpc) is a remote controller that can control electrical appliances,.
