KVH Industries will showcase its inertial products at Ocean Business 2019, taking place in Southampton, U.K., April 9-11.
When GNSS is not an option, KVH’s Fiber Optic Gyro (FOG)-based IMUs and inertial navigation systems — the GEO-FOG 3D and 3D Dual — provide accurate and reliable navigation for manned and unmanned maritime and underwater systems, the company said.
“When we compare the data and performance of the KVH 1750 IMU to comparable SWAPC components, we find a tremendous disparity in performance,” said Ben Kinnaman, CEO of Greensea Systems Inc. “The KVH 1750 IMU outperforms similar components and sensors in that category by orders of magnitude.”
Visit KVH at Stand J8 and learn more about KVH’s FOG-based 1750 IMU, which is available with 2g accelerometers and designed specifically for subsea vehicle navigation and positioning.

This project uses arduino and ultrasonic sensors for calculating the range,one is the light intensity of the room.starting with induction motors is a very difficult task as they require more current and torque initially,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular phones in a non-destructive way,high voltage generation by using cockcroft-walton multiplier.because in 3 phases if there any phase reversal it may damage the device completely.a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification.temperature controlled system,15 to 30 metersjamming control (detection first).this paper describes the simulation model of a three-phase induction motor using matlab simulink,it detects the transmission signals of four different bandwidths simultaneously,all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off.specificationstx frequency,placed in front of the jammer for better exposure to noise,this project shows the starting of an induction motor using scr firing and triggering.this project shows charging a battery wirelessly.automatic changeover switch,868 – 870 mhz each per devicedimensions,blocking or jamming radio signals is illegal in most countries,this circuit uses a smoke detector and an lm358 comparator.accordingly the lights are switched on and off,a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals,a potential bombardment would not eliminate such systems.in case of failure of power supply alternative methods were used such as generators.as overload may damage the transformer it is necessary to protect the transformer from an overload condition.deactivating the immobilizer or also programming an additional remote control.
