Mix-up Galileo Health and SISA when spare data are missing
Hi, For Galileo satellites, we've noticed that the function georinex.load inverts SISA and health value when the spare data on line BROADCAST ORBIT - 5 is missing. For example:
E03 2022 03 01 19 30 00-5.329113919288E-04-3.950617610826E-12 0.000000000000E+00 2.100000000000E+01-1.754062500000E+02 2.726899300587E-09 1.490182316738E+00 -8.136034011841E-06 1.614848151803E-04 1.358985900879E-05 5.440636070251E+03 2.430000000000E+05 3.352761268616E-08-2.121533263633E-01-6.332993507385E-08 9.566859616275E-01 4.578125000000E+01 1.171369975347E-01-5.395939048234E-09 -2.607251459631E-11 5.170000000000E+02 2.199000000000E+03 3.120000000000E+00 0.000000000000E+00 3.259629011154E-09 3.725290298462E-09 2.436840000000E+05
returns health = 3.12 and SISA = 0. This problem doesn't occur when the spare data is fixed to 0, for example:
E03 2022 03 01 19 30 00-5.329113919288E-04-3.950617610826E-12 0.000000000000E+00 2.100000000000E+01-1.754062500000E+02 2.726899300587E-09 1.490182316738E+00 -8.136034011841E-06 1.614848151803E-04 1.358985900879E-05 5.440636070251E+03 2.430000000000E+05 3.352761268616E-08-2.121533263633E-01-6.332993507385E-08 9.566859616275E-01 4.578125000000E+01 1.171369975347E-01-5.395939048234E-09 -2.607251459631E-11 2.580000000000E+02 2.199000000000E+03 0.000000000000E+00 3.120000000000E+00 0.000000000000E+00 3.259629011154E-09 0.000000000000E+00 2.437470000000E+05 0.000000000000E+00 0.000000000000E+00 0.000000000000E+00
I think it would be nice to correct this problem in the next version of georinex, since it could be very tricky. Meanwhile, I've implement the following patch based on regex: re.sub(r'(E\d{2,2}[^\n]{77,77}\n[^\n]{80,80}\n[^\n]{80,80}\n[^\n]{80,80}\n[^\n]{80,80}\n[^\n]{61,61})\n', r'\1 0.000000000000E+00\n', file_content) Do not hesitate to contact me for further details. Kind regards, Julie
