Detailed Description

Class to assign weights to satellites based on the Appendix J of MOPS document RTCA DO-229D.

This class implements an algorithm to assign weights to satellites based on the RTCA "Minimum Operational Performance Standards" (MOPS), version C (RTCA/DO-229D), sections J.2.3. "Variance of Ionospheric Delay", J.2.4. "Variance of Airborne Receiver Errors" and J.2.5. "Variance of Tropospheric errors".

It is meant to be used with class "MOPSTropModel".

int getWeights (  CommonTime &  time, Vector< SatID > &  Satellites, TabularSatStore< Xvt > &  preciseEph, Vector< double > &  ionoCorrections, Vector< double > &  elevationVector, Vector< double > &  azimuthVector, Position  rxPosition, int  rxClass = 2 )  throw (InvalidWeights) [virtual]

Computes a vector with the weights for the given satellites. Parameters: time  Epoch weights will be computed for. Satellites  Vector of satellites. preciseEph  Satellite precise ephemeris. ionoCorrections  Ionospheric corrections computed using Klobuchar model. elevationVector  Vector of elevations, in degrees. azimuthVector  Vector of azimuths, in degrees. rxPosition  Position of the receiver. rxClass  Integer indicating receiver class. according MOPS-C. It is 2 by default (conservative setting). Returns: Number of satellites with valid weights. Note: Method isValid() will return 'false' if some satellite does not have a valid weight. Also, its PRN will be set to a negative value. Definition at line 143 of file MOPSWeight.cpp. References SimpleIURAWeight::getWeights(), and GPSTK_THROW.
