Abstract: A GPS receiver includes management features and optionally the capability to correct for errors in its local oscillator which is used to sample received GPS  signals at an RF frequency from in view satellites. A downconverter is coupled to the receiver antenna for reducing the RF frequency of received signals to an intermediate frequency (IF) and a digitizer coupled to the downconverter and sampling the IF GPS signals at predetermined rates to produce sampled IF GPS  signals. Memory coupled to the digitizer stores the sampled IF GPS signals as a snapshot, and a digital signal processor (DSP) coupled to the memory performs Fast Fourier Transform (FFT) operations on the sampled IF GPS signals to provide pseudorange information, including signal preprocessing and postprocessing.  The calculation speed of pseudoranges, and sensitivity of operation, is enhanced by the transmission of Doppler frequency shifts in view of satellites to the receiver from an external source, such as a basestation.

Abstract: A system and method for mixing high viscous liquids with gas is provided. The disclosed embodiments include a reactor or mixing vessel having a draft tube disposed therein, a gas injection subsystem adapted to inject gas into the reactor or mixing vessel proximate the entrance of the draft tube. The embodiments also include an agitator disposed within the draft tube which makes the draft tube the primary site for the gas-liquid mixing. In particular, the agitator is adapted to create gas bubbles having an average diameter between about 0.3 mm and 3.0 mm which are then ejected into the reactor or mixing vessel. The mass transfer efficiency associated with the present system and method is enhanced from the combined effect of gas dissolution into the high viscous liquid within the draft tube and greater bubble residence time within the high viscous liquid.
