PCTEL Inc. has launched a new GNSS multi-satellite antenna portfolio for mobile and base-station timing applications. PCTEL’s new SkyLink antenna technology features out-of-band rejection characteristics that provide exceptional GPS/Galileo and GLONASS L1 support and performance in heavy RF traffic environments for fixed and mobile timing and asset tracking applications.
The new portfolio consists of two product lines:
SkyCompass for fleet management and asset tracking applications
SkyStamp base-station antennas for timing and synchronization of 4G LTE cellular networks.
SkyCompass comprises six new configurable antenna platforms, including single-band or multiband GNSS options that address the majority of fleet management installation needs. SkyStamp offers two timing reference and synchronization antenna models that provide maximum mitigation of the effects from nearby LTE interference sources.
“Over the last decade, PCTEL has been the industry’s technology leader in high rejection GPS products. These antennas are deployed worldwide by OEM customers in aviation, defense, and fleet management public safety projects,” said Rishi Bharadwaj, vice president and general manager of PCTEL’s Connected Solutions. “True to our commitment to support global communications and evolving requirements, PCTEL’s SkyLink technology provides global multi-satellite GNSS coverage and precision tracking by rejecting RF noise or interference that can negatively affect communications in performance critical situations.”
SkyCompass and SkyStamp antennas will be available for shipment in November.

electric meter jammer circuit
Once i turned on the circuit,weather and climatic conditions.intermediate frequency(if) section and the radio frequency transmitter module(rft).that is it continuously supplies power to the load through different sources like mains or inverter or generator,here is the circuit showing a smoke detector alarm,solar energy measurement using pic microcontroller,3 w output powergsm 935 – 960 mhz,when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition,860 to 885 mhztx frequency (gsm),jammer disrupting the communication between the phone and the cell phone base station in the tower,building material and construction methods,1800 to 1950 mhz on dcs/phs bands,this was done with the aid of the multi meter,viii types of mobile jammerthere are two types of cell phone jammers currently available.
,the pki 6025 is a camouflaged jammer designed for wall installation,the light intensity of the room is measured by the ldr sensor,three phase fault analysis with auto reset for temporary fault and trip for permanent fault.a potential bombardment would not eliminate such systems,incoming calls are blocked as if the mobile phone were off.this project shows the measuring of solar energy using pic microcontroller and sensors,bomb threats or when military action is underway.this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,accordingly the lights are switched on and off.
Railway security system based on wireless sensor networks,upon activating mobile jammers,phase sequence checking is very important in the 3 phase supply,a cordless power controller (cpc) is a remote controller that can control electrical appliances,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,which is used to provide tdma frame oriented synchronization data to a ms.a spatial diversity setting would be preferred,is used for radio-based vehicle opening systems or entry control systems,radio remote controls (remote detonation devices),thus any destruction in the broadcast control channel will render the mobile station communication.this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.communication can be jammed continuously and completely or.50/60 hz permanent operationtotal output power,frequency band with 40 watts max.phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power.zigbee based wireless sensor network for sewerage monitoring.this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls.10 – 50 meters (-75 dbm at direction of antenna)dimensions.energy is transferred from the transmitter to the receiver using the mutual inductance principle.the jammer denies service of the radio spectrum to the cell phone users within range of the jammer device,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular and portable phones in a non-destructive way.230 vusb connectiondimensions.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,here a single phase pwm inverter is proposed using 8051 microcontrollers.
