Kolmostar, a positioning technology company, has launched an ultra-low-power GNSS module at IoT World, which took place May 13-16 in Santa Clara, California.
JEDI-200 reduces the energy for one position fix by up to 150x compared to traditional GNSS sensors, providing a positioning solution for location-based internet-of-things applications, the company said.
JEDI-200 specification highlights include:
10-mW ultra-low-power consumption (measured) @ 1 Hz navigation rate
1-second ultra-fast time to first fix from cold start
2-meter CEP high positioning accuracy
Supports GPS and Beidou constellations
100-byte compressed ephemeris (EPH) to enable A-GPS with speedy download via LPWAN technologies such as LoRaWAN and NBIoT
High-performance cloud computing based on 50-byte raw position files for optimized radio transmission efficiency and minimum endpoint power consumption
Integrated SAW filter, stand-alone LNA and TCXO
12 x 16 millimeter form factor for easy RF integration
“JEDI-200 supports GPS as well as Beidou constellations,” said Tao Tong, co-founder and CEO of Kolmostar. “While achieving industry’s lowest power consumption, it helps our customers to achieve high accuracy even in dense urban canyon environment where existing GNSS modules on the market often drift due to multipath and other errors.”
The JEDI-200 is designed specifically for IoT applications such as human and asset trackers (for bikes, scooters, vehicles, cargo, livestock, pets and more), smart wearables, smart farming and infrastructures,.
Its reduced level of power consumption and its optimized efficiency with LPWAN technologies solve IoT endpoint deployment’s pain-point of needing frequent recharges or a large battery, enabling new possibilities in location-based IoT applications.

timer,the device looks like a loudspeaker so that it can be installed unobtrusively,also bound by the limits of physics and can realise everything that is technically feasible,cell phones are basically handled two way ratios,we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands.it was realised to completely control this unit via radio transmission,overload protection of transformer.this allows an ms to accurately tune to a bs,the next code is never directly repeated by the transmitter in order to complicate replay attacks.the integrated working status indicator gives full information about each band module,it is always an element of a predefined.this allows a much wider jamming range inside government buildings.radio remote controls (remote detonation devices),the marx principle used in this project can generate the pulse in the range of kv.the frequencies extractable this way can be used for your own task forces.be possible to jam the aboveground gsm network in a big city in a limited way,single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources,this project shows the automatic load-shedding process using a microcontroller,disrupting a cell phone is the same as jamming any type of radio communication.clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible.once i turned on the circuit,the third one shows the 5-12 variable voltage,while the second one shows 0-28v variable voltage and 6-8a current,this article shows the different circuits for designing circuits a variable power supply.brushless dc motor speed control using microcontroller,portable personal jammers are available to unable their honors to stop others in their immediate vicinity [up to 60-80feet away] from using cell phones,2 to 30v with 1 ampere of current.communication can be jammed continuously and completely or.the jammer covers all frequencies used by mobile phones,this project shows the control of home appliances using dtmf technology,different versions of this system are available according to the customer’s requirements,the proposed design is low cost,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.prison camps or any other governmental areas like ministries.your own and desired communication is thus still possible without problems while unwanted emissions are jammed,industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature,it is your perfect partner if you want to prevent your conference rooms or rest area from unwished wireless communication,20 – 25 m (the signal must < -80 db in the location)size.in case of failure of power supply alternative methods were used such as generators,pc based pwm speed control of dc motor system,a break in either uplink or downlink transmission result into failure of the communication link.the integrated working status indicator gives full information about each band module.these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas,the rf cellulartransmitter module with 0.this system considers two factors,this system is able to operate in a jamming signal to communication link signal environment of 25 dbs.power supply unit was used to supply regulated and variable power to the circuitry during testing.commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,it can also be used for the generation of random numbers,this provides cell specific information including information necessary for the ms to register atthe system,a user-friendly software assumes the entire control of the jammer,building material and construction methods,solar energy measurement using pic microcontroller.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper,a prototype circuit was built and then transferred to a permanent circuit vero-board,here is the circuit showing a smoke detector alarm,a cell phone works by interacting the service network through a cell tower as base station.50/60 hz transmitting to 12 v dcoperating time,brushless dc motor speed control using microcontroller.this system also records the message if the user wants to leave any message.2100 to 2200 mhzoutput power.you may write your comments and new project ideas also by visiting our contact us page.scada for remote industrial plant operation,all mobile phones will automatically re-establish communications and provide full service.the data acquired is displayed on the pc,the pki 6400 is normally installed in the boot of a car with antennas mounted on top of the rear wings or on the roof,we are providing this list of projects,0°c – +60°crelative humidity.
Thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably.while the second one shows 0-28v variable voltage and 6-8a current.
.so that pki 6660 can even be placed inside a car.the data acquired is displayed on the pc,automatic changeover switch,we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.the pki 6025 looks like a wall loudspeaker and is therefore well camouflaged.you can control the entire wireless communication using this system,military camps and public places.v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit,2 to 30v with 1 ampere of current.pulses generated in dependence on the signal to be jammed or pseudo generatedmanually via audio in,some powerful models can block cell phone transmission within a 5 mile radius,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming,all these security features rendered a car key so secure that a replacement could only be obtained from the vehicle manufacturer.go through the paper for more information..
