Alternative Characterization of Analog Signal Deformation for GNSS‐GPS Satellites
Analog Signal Deformation GNSS‐GPS Satellites
2015/6/24
Currently, analog signal deformation is described using individual-chip step response curves for each GPS/WAAS-GEO satellite. Such a set of curves is helpful– it allows us to have an overall idea of t...

With more than 70 navigation satellites orbiting the Earth,global navigation satellite systems (GNSS) users are fas-cinated to use multiple constellations to enhance position-ing availability, accurac...
Synthesis and characterization by infrared spectroscopy of hydantoin-based bonding agents, used in composite propellants
Hydantoin Synthesis Characterization MIR Composite propellant
2010/10/25
Reactions to obtain hydantoin derivatives were carried out with 5,5-dimethylhydantoin and short-chain aldehydes. Monitoring of the reactions was performed using qualitative mid-infrared spectroscopy (...
