pyacs.sol.sinex module¶

pyacs.sol.sinex.glx2snx(glx, snx, dir_snx='.')[source]¶

converts a GLOBK glx file into a sinex file

pyacs.sol.sinex.snx2ssc(snx, ssc, dir_ssc)[source]¶

simplifies a sinex file into a ssc file

pyacs.sol.sinex.glred_1_day(glx, dir_prt, dir_log, apr, eq_rename=None)[source]¶

run glred over a day

class pyacs.sol.sinex.SSinex(name=None, estimates=None, VCV=None)[source]¶

Bases: object

Sinex class: reads and manipulates a Sinex solution. Sinex (Solution/Technique Independent Exchange format) : Sinex format handling Description of the Sinex format is available at: http://www.iers.org/documents/ac/sinex/sinex_v210_proposal.pdf

classmethod from_sinex(snx)[source]¶

Constructs a PYACS Sinex instance from a P. Rebishung sinex instance

clear()[source]¶

Clear the sinex

add_site(M)[source]¶

Adds a Gpoint M in the current Sinex instance

subset_from_code(lcode, lsoln=None)[source]¶

Takes a subset from a SINEX according to a list of code and optionally a list of associated soln. Returns a dictionary of Gpoint with key (code,soln)

subset_from_keys(H)[source]¶

Takes a subset from a SINEX according to the key of a dictionary made of (code,soln) Returns a dictionary of Gpoint with key (code,soln)

apply_helmert(T, verbose=True)[source]¶

Applies an Helmert transformation to a SINEX instance returns a new SINEX instance

write_tsxyz(fname, HCOV=None)[source]¶

Write a tsxyz file from the current Sinex instance

common(H_Gpoint, prefit=3.5, strict=True, verbose=True)[source]¶

Returns a dictionary of Gpoint common to the current Sinex object and a dictionary (code,soln) of Gpoint Coordinates will be the ones from the Sinex and NOT from the list of Gpoints commons point are points with the same code pt and soln

read_section_estimate(lexclude=[], lonly=[], discontinuity=None, rename=None, verbose=False)[source]¶

Reads the ESTIMATE section of a SINEX file. a dictionary with double key 4-letters code and SOLN

Parameters

• lexclude – list of code to be excluded from reading

• lonly – lonly code on lonly will be considered

• discontinuity – if provided, discontinuity will be used to populate the SOLN field.

Generated by the Discontinuity module usually from a IGS soln file. :param rename: a dictionary having as key the sinex file for which rename will be applied and values a list of tuples (‘OLD_CODE’,’NEW_CODE’). The dictionary is usually generated by the Read_Conf_Pyacs module :param verbose: boolean for verbose mode

Returns

a dictionary with double key 4-letters CODE and SOLN and values of Gpoint instance

Note

Strictly, a point in a SINEX file is defined by several codes, including CODE, PT, DOMES and SOLN. The choice here is to ignore the PT and DOMES for versatility.

write_sinex(sinex_name, Agency_Code='IRD')[source]¶

get_STA(code, epoch, soln=None, soln_file=None, psd_file=None, discontinuity=None, verbose=False)[source]¶

Provides the predicted coordinates for a site at a given epoch. Accounts for soln and psd if provided.

print_STA(code, soln=None)[source]¶

print STA values for a given code and optional soln

add_to_STA(code, soln, add_sta)[source]¶

add sta [dx,dx,dz] to STA values for a given code and soln

change_STA(code, soln, add_sta)[source]¶

change STA values for a given code and soln

site(code, soln)[source]¶

return site for a given code and soln

info_gpoint(code, soln=None)[source]¶

Print info for a given code and optionally soln

lcode()[source]¶

Returns a list of all point codes in current Sinex object

read_apr(lexclude=[], discontinuity=None, rename=None, verbose=False)[source]¶

Reads a Globk apr file.

Parameters

• lexclude – list of code to be excluded from reading

• discontinuity – if provided, discontinuity will be used to populate the SOLN field.

Generated by the Discontinuity module usually from a IGS soln file. :param rename: a dictionary having as key the sinex file for which rename will be applied and values a list of tuples (‘OLD_CODE’,’NEW_CODE’). The dictionary is usually generated by the Read_Conf_Pyacs module :param verbose: boolean for verbose mode

Returns

a dictionary with double key 4-letters CODE and SOLN and values of Gpoint instance
