MEASUREMENT MODELS
-----------------------------------------------------------------------------
Preprocessing : Delete outliers and detect cycle slips, by processing
undifferenced phase and pseudorange data. Cycle slips
are detected by using linear combinations of phase and code data,
the wide-lane combination, and the ionospheric, or narrow-lane, combination.
Data decimated to 5 minutes.
Basic Observable : Undifferenced ionosphere-free carrier phase
Undifferenced ionosphere-free range
Elevation angle cutoff: 7 degrees.
Elevation dependent weighed scheme: sqrt(sin)
Data sampling rate: 5 minutes
Data sigma for phase data type: 1 cm
Data sigma for range data type: 1 m
Modelled : Undifferenced data, ionosphere-free linear combination
Observable
Ground antenna : absolute PCV (individual/type mean) are applied
Troposphere : Dry priori model: exponential
Mapping function: VMF for final solutions; VMF_FC for rapid, GMF for hourly solutions
Estimation : zenith path delays and horizontal gradients
every 5 minutes for each station
Ionosphere : ionosphere eliminated by forming the ionosphere-free linear
combination of GNSS observables.
Second order iono correction applied for final solutions
-----------------------------------------------------------------------------
ESTIMATED PARAMETERS (APRIORI VALUES & SIGMAS)
-----------------------------------------------------------------------------
Adjustment : Square Root Information (Kalman type) Filter (SRIF)
Rejection Criter : No rejection during parameter estimation procedure.
Outliers are marked during pre-processing step.
Station : PPP solutions are carried. Reference frame correlated
coordinates noise added aposteriori.
Troposphere : Zenith delays and horizontal gradients estimated as stochastics
at each data interval (5 min) for each station.
Ionospheric : Not estimated.
Ambiguity : Float
Receiver clock : Receiver clock biases are estimated every 5 minutes as white noise parameters.
bias
Orbits and ERPs : CODE rapid product for final/rapid solutions
IGS ultra-rapid product for hourly solutions
Tidal : Ocean loading: FES2004 applied
coefficients provided by H.G.Scherneck.
Atmospheric loading: not applied.
Solid Earth tides : applied (IERS Conventions 1996,2000)
