Ajay Sandeep Vemuru

Objective:

To contribute my intellectual abilities and problem solving analytical skills to a highly innovative

and dynamic navigation company for the benefit of both the organization and me

Experience:

Study of the effects of Ionosphere such as amplitude fluctuations and phase scintillations on

performance of receivers (Ohio University custom built and NovAtel EURO 3M & OEM v’s)

installed at HAARP facility, Alaska using artificial ionospheric heating

Presently working on the algorithm development to reliably track the GPS signal with rapid

fluctuations of signal parameters in low signal power environment

Implementation of accurate carrier and code phase tracking algorithms with navigation data

bit detection and GPS time decoding for accurate time mismatch calculations between two

different receivers

Performance analysis of both block processing and sequential processing of GPS data

Radio link implementation at Electronics and Radar Development Establishment, India

involving the design of a wireless link including antenna fabrication, protocol development

and implementation

‘Optical Characterization of III-Nitride Thin Film Waveguide Slabs Implanted with Rare

Earth Ions for Light Emitting Devices’ a project which won the student enhancement award

and supported by Ohio University, involved the measurement of absorption and emission

cross sections of thin films

Integrate measurements of equipments such as CCD camera, spectrograph and

monochromator using drivers developed in ‘Turbo C’. The driver was also used for data

acquisition; using serial ports and interrupts, in photoluminescence excitation experiment in

lab

Data Acquisition using Device drivers in ‘Turbo C’ at Defense Research and Development

Laboratory, India to precisely control the trajectory of a missile system
