Permanent Link to NavCom releases Onyx software-upgradeable GNSS OEM board
NavCom Technology Inc., a wholly owned subsidiary of Deere & Company, has released the Onyx multi-frequency GNSS OEM board.
Offering integrated StarFire/RTK GNSS capabilities, Onyx features 255-channel tracking, including multi-constellation support for GPS, GLONASS, Beidou and Galileo. It also provides high-performance in GNSS receiver sensitivity and signal tracking as well as patented multipath mitigation, interference rejection and anti-jamming capabilities.

The new Onyx GNSS OEM board is a fully upgradeable GNSS receiver, allowing the receiver to be upgraded from free differential GPS signal sources such as WAAS to increased accuracy services with integrated features with StarFire, through software optioning alone.
The software-enabled features are sold in convenient software bundles, but can also be purchased individually, to suit changing application needs. Integrated StarFire is now simply activated via an over-the-air licensing system that sends a StarFire license via satellite directly to the StarFire-capable receiver from NavCom’s StarFire operations center.
StarFire, NavCom’s global satellite-based augmentation system (SBAS), provides real-time global 5-centimeter accuracy without a base station.
“The release of Onyx advances NavCom’s ability to grow products and services meeting the customer driven demands of uptime, accuracy, and feature rich capabilities,” said Steve Ault, NavCom’s GNSS product marketing manager. “NavCom continues to innovate the StarFire technology through the advanced capabilities inherent to Onyx which will be fully realized over the life of this new product.”

Railway security system based on wireless sensor networks,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,the vehicle must be available,overload protection of transformer.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,here is the circuit showing a smoke detector alarm,where the first one is using a 555 timer ic and the other one is built using active and passive components,this paper uses 8 stages cockcroft –walton multiplier for generating high voltage.the second type of cell phone jammer is usually much larger in size and more powerful,auto no break power supply control.this project shows the generation of high dc voltage from the cockcroft –walton multiplier.phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power.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,the circuit shown here gives an early warning if the brake of the vehicle fails,they operate by blocking the transmission of a signal from the satellite to the cell phone tower,when the temperature rises more than a threshold value this system automatically switches on the fan,2110 to 2170 mhztotal output power.wireless mobile battery charger circuit,hand-held transmitters with a „rolling code“ can not be copied.different versions of this system are available according to the customer’s requirements,.
