% Model a rate gyro. Includes all noise sources
and temperature dependence. The data structure is:
h.measurement
h.scaleFactor
h.bias
h.temp
h.tempNominal
h.maxRate
h.unitVector(3)
h.resolution
h.deadband
h.accelCoeff(2) [g g^2]
h.biasTempCoeff(n) [(temp - tempNominal) (temp - tempNominal)^2 ... ]
h.biasDayToDay
h.biasRandomDrift
h.biasRandomWalk (Optical Gyros)
h.scaleFactorDayToDay
h.scaleFactorTempCoeff(n) [(temp - tempNominal) (temp - tempNominal)^2 ... ]
h.scaleFactorPositiveCoeff(n) [omega omega^2 ... ]
h.scaleFactorNegativeCoeff(n) [omega omega^2 ... ]
h.initialize (0 means initialize and apply the day-to-day uncertainties)
Since version 2.
