10. Station Coordinates and Velocities Table 10.2: List of programs used for coordinate/velocity estimation. Program Input data type Location Station Coordinates CODSPP code, zero-difference ”Menu>Processing>Code-based clock synchronization” MAUPRP phase, epoch-difference ”Menu>Processing>Phase preprocessing” GPSEST code and/or phase, zero- or ”Menu>Processing>Parameter estimation” double-difference ADDNEQ2 combination on NEQ level ”Menu>Processing>Normal equation stacking” Station Velocities ADDNEQ2 combination on NEQ level ”Menu>Processing>Normal equation stacking” to generate good a priori coordinates – as recommended in Section 3.5 – these preliminary coordinate results are not needed anymore. Otherwise, they may be used as a priori information in subsequent analysis steps. Although GPSEST is still the main parameter estimation program in the Bernese GPS Software. It is gradually superseded by ADDNEQ2 when it comes to coordinate estimation. If final coordinate results are to be estimated, GPSEST is mainly used to create a normal equation file. The geodetic datum is then defined in a separate step with ADDNEQ2. Multisession solutions and velocity estimation are only possible with ADDNEQ2, anyhow. The program panels dedicated to datum definition are very similar in programs GPSEST and ADDNEQ2. The only differences are the minimum constraint solution and the velocity related panel, which both are not available in GPSEST. Figure 10.1 shows the corresponding ADDNEQ2 panel. The options let you select one of the datum definition types described in Section 10.2.2 and if necessary the corresponding constraints or minimum constraint conditions. The comboboxes next to each datum definition type offer several possibilities for reference site selection (stations to which the datum definition should apply). The FIRST, LAST, or ALL stations may be selected without any additional user interaction. The other three possibilities need further specifications in a subsequent panel. Reference sites can be picked by hand from a list of stations (MANUAL), taken from a station selection or sigma file (FROM FILE), or from a coordinate file depending on the corresponding flags (WITH FLAG). If coordinates are to be constrained FROM FILE, not only the list of reference sites but also the a priori sigmas are taken from that file. Sections 22.8.13 and 22.8.12 provide more details on station selection and station sigma files. Please note that the afore mentioned datum definition options do not apply for kinematic stations. The datum may be analogously defined for velocities in program ADDNEQ2. The a priori coordinates of the reference sites should always refer to the current epoch of the processed session. If the reference coordinates refer to a different epoch they must be extrapolated accordingly with program COOVEL before being introduced in GPSEST. For program ADDNEQ2 this is not necessary, provided that an a priori velocity file is specified in the input panel. In that case ADDNEQ2 internally propagates the coordinates before the normal equation system is solved. Page 218 AIUB
10.3 Coordinate and Velocity Estimation in Practice Figure 10.1: Datum definition options in ADDNEQ2. 10.3.1 Program Output and Result Files Related to Coordinates GPSEST and ADDNEQ2 provide very similar coordinate and velocity 2 related sections in the program output files. All introduced station coordinates and velocities (if set up) are reported in the first part of the program output. A priori coordinates and velocities are tabulated in a geocentric, Earth-fixed, cartesian system as well as in latitude, longitude and height. Each station is marked with one of the following flags: ESTIM : station coordinates/velocities are estimated, FIXED : fixed on their a priori values, HELMR : estimated and used to define the minimum constraints condition, or ECCEN : refer to an eccenter station. The next output section lists the coordinate/velocity constraints for each station or – in case of a minimum constraint solution – the network constraints. Figure 10.2 shows an excerpt of the result part in the program output (from ADDNEQ2, including estimated velocities). Cartesian coordinates are given in units of meters, geographical coordinates in degree/minute/second, and velocities in meters per year. The output is quite self explaining, only columns (7)–(10) need further explanation: 2 Velocity related information is only available in ADDNEQ2. Bernese GPS Software Version 5.0 Page 219
