GpsTools : Parameter Estimator

Item		Operation
Satellites		The satellite list for estimation is shown here. To modify the list, push button "Satellites..." and edit it in Satellite List Editor dialog.
Receivers		The receiver (station) list for estimation is shown here. To modify the list, push button "Receivers..." and edit it in Receiver List Editor dialog.
Estimation Start Time		Set estimation start time (year/month/day hour:minute:sec) in GPS Time.
Estimation End Time		Set estimation end time (year/month/day hour:minute:sec) in GPS Time.
Estimation Interval		Set estimation interval (sec). The interval has to be in the range from 0.01 to 86400 sec. The interval also has to be multiples of sampling interval of the observation data.
Est Unit/Overlap Time		Set estimation unit time (hr) and the estimation overlap time (hr). The estimation unit time is used to separate sessions. Each session is executed in order and results of each session are separately saved. For example, in case that the estimation start/end time is 2004/1/1 2:30-9:30, the estimation interval is 60 sec and the estimation unit time is 3 hr, the estimation period is separated into sessions of 2:30-2:59, 3:00-5:59, 6:00-8:59 and 9:00-9:30. If you intend continuous and not separated session, set it long enough. The overlap time is length of additional estimation period before and after a session. In usual, set it 0. Refer Definition of Processing Unit Time and Overlap Time for details.
Exec Obs Data Editor		Set execution condition of Observation Data Editor. - ON : execute observation data editor and generate clean observation data. The parameters for the observation data editor can be settled by Observation Data Editor Setting dialog. - OFF : not execute observation data editor. If you intend to use clean observation data which already exist by executing the editor previously, set it OFF.
Exec Parameter Estimator		Set execution passes of Parameter Estimator. - OFF : no execution of Parameter Estimator. - 1pass(F) : 1-pass (forward pass) - 2pass(FB) : 2-passes (forward and backward passes) - 3pass(FBF) : 3-passes (forward, backward and forward passes)
Estimation Strategy		Set estimation strategy for Parameter Estimator. - ZD/PPP : zero-differenced measurement or PPP (precise point positioning) - DD : double-differenced measurement (current version does not support DD)
Est/Fixed Parameters		Set estimated or fixed parameters for Parameter Estimator. Push the button and set conditions by Estimated/Fixed Parameters Setting dialog.
Baselines		Set baselines for Parameter Estimator in case of DD as the estimation strategy. Push the button and set conditions by Baseline Setting dialog.
Satellite Clock Model		Set the model of satellite clock variation in case of estimating satellite clock. - White-Noise : white-noise process - Gauss-Marcov : Gauss-Marcov process
Receiver Clock Model		Set the model of receiver clock variation in case of estimating receiver clock. - White-Noise : white-noise process - Gauss-Marcov : Gauss-Marcov process
Receiver Position Model		Set the model of receiver position variation in case of estimating receiver position. - Static : static or random-walk process - Kinematic : kinematic or white-noise process In case of estimating the position of stationary receiver, set it Static and set the process noise of receiver position 0. In case of estimating the position of low-dynamics receiver, set it Static and set the process noise of receiver appropriate value (>0).
Clock Reference		Set the reference clock receiver in case of estimating satellite clock. The estimated clock is relative value to the specified receiver clock. If setting it blank, no reference clock is used.
Raw Observation Data		Set the data file and file name type of input raw observation data. The raw observation data have to have the following file name in [...]. - RINEX : RINEX OBS [rrrrddd0.yyo] - RINEX (3H) : RINEX OBS (3H) [rrrrdddh.yyo] - RINEX (1H) : RINEX OBS (1H) [rrrrdddx.yyo] - RINEX (15min) : RINEX OBS (15min) [rrrrdddxmm.yyo] (rrrr : receiver/station id (4 characters), ddd : day of year, yy : year (2 digits), h : 1,2,.. (=0:00,3:00,...), x : a,b,c,... (=0:00,1:00,2:00,...), mm : minutes) If the input file does not comply the name above, rename the input file. The raw observation data file can be compressed by Hatanaka-Compression, compress or gzip. If the file is compressed, the file extension has to be comply to the compression. (e.g., : .yyo.Z, .yyo.gz, .yyd, .yyd.Z, *.yyd.gz)
