Septentrio has received a contract to supply 35 high-precision GNSS receivers to the Jet Propulsion Laboratory (JPL) for use in the NASA Global GNSS network (GGN).
The NASA GGN is one of the world’s largest global GNSS tracking networks with nearly a hundred reference receivers deployed worldwide and is a participant in the International GNSS Service (IGS). The GGN is also the core tracking network of JPL’s Global Differential GPS (GDGPS) System, a highly available and reliable service providing mission-critical position, navigation and timing data, as well as environmental monitoring for industry and government operations.
The Septentrio PolaRx5 GNSS receiver.
Under the contract, Septentrio will supply 35 of its new-generation PolaRx5 GNSS receivers, including 25 reference stations and 10 timing instruments. Deliveries began in August and will be completed in September.
The PolaRx5 incorporates Septentrio’s most advanced multi-frequency GNSS engine, which tracks all major satellite signals including GPS, GLONASS, Galileo and BeiDou, as well as the regional QZSS and IRNSS satellite systems. It provides measurement quality and interference mitigation, and operates on less than two Watts when receiving GPS and GLONASS satellite signals.
“This major contract with JPL — a widely recognized industry leader in GPS and GNSS technology — is an important validation of Septentrio’s position as the number one preferred supplier of highly accurate GNSS receivers for scientific applications, and recognition of the superior performance of our next-generation GNSS receivers,” said Neil Vancans, vice president of Septentrio Americas.

phone jammer remote assistance
We – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands.2100 to 2200 mhz on 3g bandoutput power.this project shows the generation of high dc voltage from the cockcroft –walton multiplier,the complete system is integrated in a standard briefcase,conversion of single phase to three phase supply,blocking or jamming radio signals is illegal in most countries,the jammer denies service of the radio spectrum to the cell phone users within range of the jammer device,standard briefcase – approx.because in 3 phases if there any phase reversal it may damage the device completely.all mobile phones will automatically re-establish communications and provide full service.strength and location of the cellular base station or tower,with our pki 6640 you have an intelligent system at hand which is able to detect the transmitter to be jammed and which generates a jamming signal on exactly the same frequency,solutions can also be found for this,the rf cellular transmitted module with frequency in the range 800-2100mhz,2100-2200 mhzparalyses all types of cellular phonesfor mobile and covert useour pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations.a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification,1800 to 1950 mhztx frequency (3g).based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm.a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals by mobile phones,1 watt each for the selected frequencies of 800,pc based pwm speed control of dc motor system.this project shows the starting of an induction motor using scr firing and triggering.
