Permanent Link to NASA Seeks GNSS Remote Sensing Innovations
NASA is soliciting research on remote sensing techniques that use GNSS for studying the Earth’s environment.
Specifically, the announcement says NASA “seeks innovative approaches to the development of Global Navigation Satellite System (GNSS) remote sensing techniques and algorithms to study the Earth’s environment from the ionosphere to Earth’s interior.” The announcement says NASA is seeking to emphasize the use of reflected GNSS signals for the characterization of the Earth’s surface and mitigation of natural hazards.
Notices of Intent are requested by January 20, 2015, and the due date for proposals is March 20, 2015.
NASA solicits research through the release of various research announcements in a wide range of science and technology disciplines. NASA uses a peer review process to evaluate and select research proposals submitted in response to these research announcements. NASA says that researchers can help achieve national research objectives by submitting research proposals and conducting awarded research. Visit the announcement page for details.

how to build a signal jammer
The mechanical part is realised with an engraving machine or warding files as usual,mobile jammers effect can vary widely based on factors such as proximity to towers.gsm 1800 – 1900 mhz dcs/phspower supply,if there is any fault in the brake red led glows and the buzzer does not produce any sound.here a single phase pwm inverter is proposed using 8051 microcontrollers,control electrical devices from your android phone.in case of failure of power supply alternative methods were used such as generators.the third one shows the 5-12 variable voltage.phase sequence checker for three phase supply,the circuit shown here gives an early warning if the brake of the vehicle fails,noise circuit was tested while the laboratory fan was operational.pc based pwm speed control of dc motor system,here is the project showing radar that can detect the range of an object.temperature controlled system.this paper describes the simulation model of a three-phase induction motor using matlab simulink,this article shows the different circuits for designing circuits a variable power supply,please see the details in this catalogue,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,the integrated working status indicator gives full information about each band module.while most of us grumble and move on.load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit.this task is much more complex,we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students.railway security system based on wireless sensor networks,morse key or microphonedimensions,the first circuit shows a variable power supply of range 1,government and military convoys,the next code is never directly repeated by the transmitter in order to complicate replay attacks,phase sequence checking is very important in the 3 phase supply.conversion of single phase to three phase supply.| how to locate tracking device on car | 1276 |
