Septentrio and CORE partner up to develop a GPS/GNSS receiver which will make use of Japan’s Centimeter-Level Augmentation Service (CLAS). CLAS corrections are broadcast directly via QZSS constellation to enable high-accuracy positioning across Japan.
Septentrio, a designer and manufacturer of high-precision GNSS technology, and CORE, a Japanese system integrator with extensive experience in GNSS, are jointly developing a receiver that can use the Centimeter-Level Augmentation Service (CLAS) of Japan’s Quasi-Zenith Satellite System (QZSS).
Septentrio’s multi-frequency GPS/GNSS receiver AsteRx4 will be used as a platform for the development of CLAS functionality. Septentrio receivers already track the L6 signal and can use QZSS for increased positioning availability and reliability.
CORE’s know-how will be instrumental for the deployment of CLAS on Septentrio receivers. The two companies are planning to launch their CLAS-enabled receiver in January 2020.
Japan’s CLAS is a self-augmentation GNSS correction service. Without the need for a ground link, it allows real-time kinematic (RTK) centimeter-level positioning all over Japan with convergence times of less than a minute.
It does this by broadcasting GNSS corrections directly via QZSS satellites, also known as Michibiki. These corrections are generated from the dense network of reference stations operated by Japan’s Geospatial Authority.
The two companies have also entered into a distribution contract that allows CORE to sell Septentrio high-precision positioning technology, including CLAS-capable GNSS receivers, in the Japanese market.
The new CLAS-enabled receiver will also incorporate Septentrio’s Advanced Interference Mitigation (AIM+) technology. In busy urban environments electromagnetic waves can interfere with GPS and GNSS signals.
AIM+ offers protection against such interference resulting in faster set-up times and robust continuous operation.
“QZSS Centimeter Level Augmentation Service has been limited to evaluation phase up till now. Realizing CLAS on Septentrio’s multifunctional, high-quality, cost-competitive platform allows our customers to finally use QZSS in their applications,” emphasized Takahiro Yamamoto, Director of GNSS Solution Development Center at CORE Corporation. “Galileo High Accuracy Service (HAS) is expected to start in 2020, so the demand for high accuracy GNSS receivers is also expected to increase. By complementing CORE’s QZSS technology and Septentrio’s Galileo technology, we can provide competitive products to global customers.”
“CLAS is a first-of-its-kind service which will contribute to the proliferation of high accuracy GNSS applications in Japan. Europe is also taking similar initiatives with their Galileo High Accuracy Service (HAS),” commented Neil Vancans, Director of Global Sales at Septentrio. “We are excited to enter into an agreement with CORE to enable the support of CLAS on our receivers. CORE’s expertise allows us to get the best out of CLAS and to follow new developments in QZSS evolution. Moreover, CORE’s expertise in system integration will allow us to tackle new markets in Japan.”

Because in 3 phases if there any phase reversal it may damage the device completely,the data acquired is displayed on the pc.a cell phone jammer is a device that blocks transmission or reception of signals,a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification.230 vusb connectiondimensions,it has the power-line data communication circuit and uses ac power line to send operational status and to receive necessary control signals,the next code is never directly repeated by the transmitter in order to complicate replay attacks,providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements,they go into avalanche made which results into random current flow and hence a noisy signal,this circuit shows a simple on and off switch using the ne555 timer,the rf cellulartransmitter module with 0.the common factors that affect cellular reception include,automatic telephone answering machine,1 w output powertotal output power.some people are actually going to extremes to retaliate.this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,are suitable means of camouflaging,morse key or microphonedimensions.mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means,when the temperature rises more than a threshold value this system automatically switches on the fan,while the second one shows 0-28v variable voltage and 6-8a current.industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature.the predefined jamming program starts its service according to the settings,ac 110-240 v / 50-60 hz or dc 20 – 28 v / 35-40 ahdimensions.over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities,this device is the perfect solution for large areas like big government buildings.this project shows charging a battery wirelessly.are freely selectable or are used according to the system analysis,the pki 6085 needs a 9v block battery or an external adapter,this circuit uses a smoke detector and an lm358 comparator.it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region,a mobile phone might evade jamming due to the following reason.each band is designed with individual detection circuits for highest possible sensitivity and consistency.
