22. Data Structure<br />

(3) TYPE 003: HANDLING OF STATION PROBLEMS<br />

RXOBV3 checks the entries and does not write a <strong>Bernese</strong> observation file for a station<br />

specified in this type for the time interval processed. ADDNEQ2 pre-eliminates the<br />

corresponding station coordinates before stacking within the specified time interval.<br />

(4) TYPE 004: STATION COORDINATES AND VELOCITIES<br />

This part of file allows you to constrain the estimates of the station coordinates and/or<br />

station velocities of two stations relatively to each other. To get identical velocities for<br />

two stations the a priori velocities must be identical. It is possible to constrain north,<br />

east, and up components independently.<br />

(5) TYPE 005: HANDLING STATION TYPES<br />

In this section the “MARKER TYPE” of an antenna may be specified. This is mandatory<br />

for spaceborne receivers. Programs check the marker type inorder to distinguish<br />

ground and spaceborne receivers.<br />

Remarks<br />

• The file contains the basic station information used to check RINEX header information<br />

with RXOBV3, to update header information in <strong>Bernese</strong> observation files with<br />

CHGHED, and to check and adapt station information in ADDNEQ2. All information<br />

is centralized in one single file.<br />

• Table 22.5 lists the programs accessing the different sections of the station information<br />

file. For details concerning the use of the file during data import with RXOBV3<br />

see Section 4.2.3, for more information on how to use the file with ADDNEQ2 see<br />

Section 9.4.6 and wrt PHCCNV see Section 16.3.<br />

• Flags available in the file are currently not used.<br />

• Empty epoch fields are considered as open time interval boundaries.<br />

• For TYPE 002 and TYPE 004 values that should not be checked may be replaced by<br />

unknown/undefined (see Table 22.6).<br />
