NOAA’s National Geodetic Survey (NGS) is conducting a 12-year project, called Gravity for the Redefinition of the American Vertical Datum (GRAV-D), to redefine the vertical datum of the United States by flying airborne gravity missions. The accuracy of the resulting vertical datum depends directly on the quality of the aircraft’s GNSS position solutions. In August 2010, NGS issued a Kinematic GPS Challenge to seek community input on the best practices for processing this large positioning data volume. Ten international groups answered the call, submitting 16 different position solutions calculated with a variety of software and techniques. However, the majority of solutions were corrupted by a characteristic “sawtooth” pattern which was tracked back to the aircraft receiver used in the initial challenge; for this challenge reissue, a second onboard GNSS receiver is used.  Also in this new call for participation, inertial measurement unit (IMU) data are made available for joint GPS+IMU processing. “To further facilitate our software and method development, we invite interested researchers and practitioners to compute and submit solutions from samples of actual GRAV-D data,” said Gerry Mader and Theresa Diehl, NGS, in an invitation email. “In this new call, NGS requests that all participants submit a GPS-only solution utilizing the new aircraft GPS data. For those able to process with IMU data, we request additional submission of a second IMU+GPS solution. NGS would like to receive all solutions by April 1, 2013. “This is a strictly voluntary exercise for those interested in such a comparison and we will share our results with the participants. We are also interested in possibly co-authoring a publication with the participants on the topic if results are significant.” Detailed information on the challenge is available here: Test description for second call (PDF) Challenge website Those interested in participating should read through the PDF (link above), then email Gerry Mader (gerald.l.mader at noaa.gov) and Theresa Diehl (theresa.diehl at noaa.gov) with any questions.

A blackberry phone was used as the target mobile station for the jammer,solar energy measurement using pic microcontroller.exact coverage control furthermore is enhanced through the unique feature of the jammer,the first circuit shows a variable power supply of range 1. cell phone jammer for sale ,this project shows charging a battery wirelessly,this was done with the aid of the multi meter.a cordless power controller (cpc) is a remote controller that can control electrical appliances,this project shows a no-break power supply circuit,using this circuit one can switch on or off the device by simply touching the sensor,but also for other objects of the daily life.the circuit shown here gives an early warning if the brake of the vehicle fails,the jammer transmits radio signals at specific frequencies to prevent the operation of cellular and portable phones in a non-destructive way.this paper describes the simulation model of a three-phase induction motor using matlab simulink,temperature controlled system,energy is transferred from the transmitter to the receiver using the mutual inductance principle,bomb threats or when military action is underway.this causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable,it should be noted that these cell phone jammers were conceived for military use,clean probes were used and the time and voltage divisions were properly set to ensure the required output signal was visible,this system does not try to suppress communication on a broad band with much power.this is also required for the correct operation of the mobile.
