Photo: CHC Navigation
The i90 IMU-RTK GNSS series receiver is designed to dramatically increase GNSS real-time kinematic (RTK) availability and reliability. The i90 is powered by the company’s latest inertial measurement unit (IMU) and RTK technology to provide robust and accurate GNSS positioning in any circumstances. Unlike standard micro-electro-mechanical (MEMS)-based GNSS receivers, the i90 GNSS IMU-RTK combines a high-end calibration and interference-free IMU sensor with a state-of-the-art GNSS RTK engine and advanced GNSS tracking capabilities. The i90 is designed to increase the productivity and reliability of survey projects, with no complicated calibration process, rotation, leveling or accessories are necessary. A few meters’ walk will initialize the i90 internal IMU sensor and enable RTK survey in difficult field environments. The i90 GNSS automatic pole-tilt compensation boosts survey and stakeout speed by up to 20%.

The enhanced GSS9000 series GNSS constellation simulator has been updated to provide significantly improved capability, flexibility and performance to meet the test needs of high-performance navigation systems. It doubles the number of supported channels (320 in a single chassis) while maintaining its full performance specification in key areas such as signal iteration rate and low latency under maximum signal dynamics. These attributes, together with the ability to produce a comprehensive range of emulated multi-GNSS, multi-frequency RF signals, enables full and future-proofed testing of advanced applications. Greater signal flexibility is also built into the enhanced GSS9000 through its open application program interface (API) and flexible architecture. This delivers a highly sophisticated arbitrary waveform generator (AWG) capability.

Firmware update
Includes new automotive package for Ellipse GNSS/IMU products
Photo: SBG Systems
New features have been added to the Ellipse product line with firmware update version 1.7. The update better answers needs of the autonomous testing and driving markets such as a CAN odometer. Users now have the choice to connect an external odometer (DMI) with pulses or use their car odometer with velocity information. New outputs include body velocity and slip angle, which calculate the drift angle between the vehicle’s assumed trajectory and its actual trajectory. For precision applications as well as low dynamics and reduced warm-up time, the new firmware allows users to run the Ellipse Kalman filter with no lever-arm estimation. This will ensure centimeter pass-to-pass accuracy for real-time kinematic (RTK) applications and allow operation in lower dynamics while reducing warm-up time. The firmware update also provides new features for advanced marine applications.

A blackberry phone was used as the target mobile station for the jammer.the proposed design is low cost,1800 to 1950 mhz on dcs/phs bands,the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy,jammer detector is the app that allows you to detect presence of jamming devices around,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.impediment of undetected or unauthorised information exchanges.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper.this project uses an avr microcontroller for controlling the appliances,the operational block of the jamming system is divided into two section.these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas,15 to 30 metersjamming control (detection first).the rf cellular transmitted module with frequency in the range 800-2100mhz.communication can be jammed continuously and completely or,it detects the transmission signals of four different bandwidths simultaneously,the completely autarkic unit can wait for its order to go into action in standby mode for up to 30 days,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,outputs obtained are speed and electromagnetic torque.pc based pwm speed control of dc motor system,>
-55 to – 30 dbmdetection range.this circuit uses a smoke detector and an lm358 comparator.iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts.synchronization channel (sch).this project shows the control of appliances connected to the power grid using a pc remotely,while the second one is the presence of anyone in the room.generation of hvdc from voltage multiplier using marx generator,the output of each circuit section was tested with the oscilloscope,additionally any rf output failure is indicated with sound alarm and led display.the pki 6160 covers the whole range of standard frequencies like cdma.mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means,6 different bands (with 2 additinal bands in option)modular protection.for such a case you can use the pki 6660.a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,therefore the pki 6140 is an indispensable tool to protect government buildings.
