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 L1, L2,
P1 and P2 data, the wide-lane combination, and the
ionospheric, or narrow-lane, combination. Data is
decimated to 5 minutes.
Basic Observable : Undifferenced ionosphere-free carrier phase, LC
Undifferenced ionosphere-free pseudorange, PC
Elevation angle cutoff: 7 degrees.
Data sampling rate: 5 minutes
Data weight, LC: 1 cm
Data weight, PC: 1 m
Modelled : Undifferenced data, ionosphere-free linear combination
Observable
Ground antenna : absolute PCV are applied
Troposphere : Dry priori model: exponential
Mapping function: VMF for final solutions; GMF for rapid/hourly solutions
Estimation : zenith path delays and horizontal gradients
every 5 minutes for each station
Ionosphere : Not modelled : ionosphere eliminated by forming the
ionosphere-free linear combination of
L1 e L2.
-----------------------------------------------------------------------------
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.
All stations with residuals, w.r.t. the previous
weekly euref combined solutions, N/E>15mm and U>25mm
are flagged and removed.
Station : Solutions are carried out as "fiducial-free" through
coordinates the introduction of a priori coordinates with unique
standard deviations of +/- 1 m.
Troposphere : Zenith delays and horizontal gradients estimated as stochastics
at each data interval (5 min) for each station.
Ionospheric : Not estimated.
Ambiguity : Fixed to integer values
Satellite clock : Satellite clock biases are estimated every 5 minutes as white noise
bias parameters relative to a reference clock.
Receiver clock : Receiver clock biases are estimated every 5 minutes as white noise
bias parameters relative to a reference clock.
Orbits and ERPs : IGS final orbits & ERPs.
Tidal : Ocean loading: FES2004 applied
coefficients provided by H.G.Scherneck.
Atmospheric loading: not applied.
Solid Earth tides : applied (IERS Conventions 1996,2000)
