Granted: 2004-09-27
Abstract: FIELD: increase of accuracy of satellite navigation, in particular, methods for elimination of tropospheric and ionospheric errors of range measurement in ordinary single-frequency receivers due to special appropriate processing of code and phase measurements with the use of only that information, which is accessible to the satellite receiver in its standard operating conditions. 
     SUBSTANCE: the increase of accuracy is attained by inclusion of the parameters of vertical tropospheric and ionospheric delays as interfering ones in the number of those estimated by the results of combined radio-navigational measurements (code and phase_ and thereby exclusing the influence of the current errors (tropospheric and ionospheric) on the results of the solution of the navigational problem of determination of the co-ordinates and components of the vector of the object velocity. A good quality of estimation of these interfering parameters (their joint keenness of observation) is provided by different signs of partial derivatives of the radial velocity and range according to the ionospheric delay, and similar ones according to the tropospheric delay. The measurements are processed both by the fixed volume of the sample by the method of the least squares with weighing of disproportionate measurements (which is convenient for fixed users) and by incremental volume with the aid of the method of recurrent squares or standard Kalman filter, which is more convenient for movable objects. For recurrent processing by the method of least squares and in the Kalman filter a matrix of partial derib\vatives is formed. 
     EFFECT: enhanced accuracy due to elimination of tropospheric and ionospheric errors in an ordinary single-frequency receives using only standard accessible for it satellite navigational and measurement information.

Title: Method and device for compensating frequency error of heterodyne by controlling external conditions
IPC: H03L7/06
Filed: 2001-05-08
Granted: 2008-09-10
Abstract: The frequency error of an oscillator is minimized by characterizing the operating environment of the oscillator. An electronic device monitors parameters that are determined to have an effect on the frequency accuracy of the internal frequency source. Temperature is one parameter known to have an effect on the frequency of the internal frequency source and a primary contributor to device temperature is the RF Power Amplifier (PA). The electronic device collects and stores the activity level of the PA. The effective PA duty cycle over a predetermined period of time is calculated. The LO operating environment is stabilized by operating the PA at the calculated duty cycle when the LO is required to operate in a high stability mode.
