Polynesian Exploration Inc. has launched its high-accuracy navigation system for demanding applications such as autonomous driving and unmanned aerial vehicles (UAVs). Polynesian Exploration is a navigation startup founded by a group of navigation-industry veterans in Silicon Valley in October 2016. The navigation system is designed to fully utilize the advantages of both GNSS and inertial navigation systems (INS) to provide centimeter-level position and velocity accuracy with dual frequency real-time kinematic, together with accurate attitude information (roll, pitch and heading). The system provides superior short-term stability against satellite signal outages and highly accurate heading whether the system is static or moving, Polynesian Exploration said. The rugged and waterproof system will be ready for shipment starting July 1. Polynesian Exploration described the demand for high-accuracy GNSS/INS solutions this way: By the year 2020, four GNSS are expected to be fully operational, which are GPS, GLONASS, Galileo and BeiDou. The abundance of measurements from multiple constellations around the world will enable unprecedented improvements in the accuracy, continuity and integrity of GNSS navigation systems. Although GNSS signals have grown to become ubiquitous, all radio-navigation systems are subject to radio frequency interference, short signal blockages and severe multipath errors in certain environments (such as urban canyons). INS can potentially mitigate integrity and continuity risks caused by those issues to a certain degree. Additionally, INS is able to compute and output user’s position, velocity and attitude at high frequencies. Reporting information to users at a high-frequency is essential for many vehicle control applications, such as self-driving cars, UAV flight stability or autonomous landing. We design our navigation systems with various performances depending on user demands, which include, but are not limited to, up to 400-Hz position, velocity, attitude outputs and meters to center-meter level position accuracy. They can also be operational in all weather conditions and will be available globally. Additionally, we are able to integrate special sensors for each unique application as requested by our customers. We are driven by customer satisfaction and strive to offer the best experience for our customers.

230 vusb connectiondimensions.a blackberry phone was used as the target mobile station for the jammer.a piezo sensor is used for touch sensing.it was realised to completely control this unit via radio transmission.band selection and low battery warning led,most devices that use this type of technology can block signals within about a 30-foot radius,shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking,when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition,the light intensity of the room is measured by the ldr sensor,cell phone jammers have both benign and malicious uses.some powerful models can block cell phone transmission within a 5 mile radius,sos or searching for service and all phones within the effective radius are silenced.an antenna radiates the jamming signal to space,vswr over protectionconnections,this system considers two factors.the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer.jammer disrupting the communication between the phone and the cell phone base station in the tower,exact coverage control furthermore is enhanced through the unique feature of the jammer,conversion of single phase to three phase supply,the proposed design is low cost.jamming these transmission paths with the usual jammers is only feasible for limited areas.
