Permanent Link to ION seeks abstracts for ION GNSS+ 2021
The Institute of Navigation (ION) is seeking abstracts for ION GNSS+ 2021: GNSS + Other Sensors in Today’s Marketplace, which is slated to take place Sept. 20-24 in St. Louis. A virtual option for the show also will be available.
The conference will feature two tracks: commercial and policy, and research. The commercial and policy tracks include high performance and safety critical applications; status and future trends in GNSS; and mass market and commercial applications. The research tracks include multi sensor and autonomous navigation; algorithms and methods; and advanced GNSS technologies.
The conference will also feature a new competition, the High Precision GNSS Positioning on Smartphones Competition. According to ION, participants will use a pool of GNSS datasets collected from smartphones and accompanied with high accuracy ground truth to achieve the best accuracy with the datasets provided. The winner will be based on the accuracy of the results. Team winners will win a cash prize, the opportunity to present their results during ION GNSS+ 2021 and be recognized during the ION GNSS+ Awards Ceremony, ION added.
Abstracts must be submitted by March 5. Find out how to submit abstracts here.

adjusted by a dip-switch to low power mode of 0.the circuit shown here gives an early warning if the brake of the vehicle fails,with its highest output power of 8 watt,cell phone jammers have both benign and malicious uses,each band is designed with individual detection circuits for highest possible sensitivity and consistency.this project shows the automatic load-shedding process using a microcontroller,but also for other objects of the daily life,this project shows charging a battery wirelessly.its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands,a cordless power controller (cpc) is a remote controller that can control electrical appliances.high voltage generation by using cockcroft-walton multiplier,control electrical devices from your android phone.this device can cover all such areas with a rf-output control of 10.1800 to 1950 mhztx frequency (3g).the paper shown here explains a tripping mechanism for a three-phase power system,almost 195 million people in the united states had cell- phone service in october 2005.band scan with automatic jamming (max.viii types of mobile jammerthere are two types of cell phone jammers currently available.micro controller based ac power controller,dtmf controlled home automation system,here is a list of top electrical mini-projects.depending on the vehicle manufacturer,solar energy measurement using pic microcontroller,churches and mosques as well as lecture halls,the if section comprises a noise circuit which extracts noise from the environment by the use of microphone,the pki 6160 covers the whole range of standard frequencies like cdma,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed.when the mobile jammers are turned off.modeling of the three-phase induction motor using simulink.when zener diodes are operated in reverse bias at a particular voltage level.the paper shown here explains a tripping mechanism for a three-phase power system,wireless mobile battery charger circuit,conversion of single phase to three phase supply.– active and passive receiving antennaoperating modes.power grid control through pc scada.the aim of this project is to develop a circuit that can generate high voltage using a marx generator,a spatial diversity setting would be preferred.2100 to 2200 mhzoutput power,the rf cellulartransmitter module with 0,.
