TayAbsTEC is software for calculation of the absolute vertical total electron content (TEC) in the ionosphere and differential code biases (DCB) values. TayAbsTEC uses a slant TEC value derived from global navigation satellite systems data by tec-suite.
Just download and extract TayAbsTEC archive wherever you want (for Windows only yet).
TayAbsTEC takes tec-suite output files as an input. These files must contain the following data:
- tec.p1p2 or tec.c1p2
In order to get it you must set
recFields parameter in
tecs.cfg to the following:
recFileds = 'tsn, hour, el, az, tec.l1l2, tec.p1p2, validity'
For further information see tec-suite documentation.
Once you get tec-suite out files, you can
c:\dat\ path to .dat files, outputted by tec-suite 10 elevation angle cutoff 2009 year for which evaluation is performed 9 day of year for which evaluation is performed joze site for which evaluation is performed 0.5 time step in hours 0.97 the correcting coefficient: 0.97 - for mid-latitude stations, 0.94 - for high-latitude stations, 0.87 - for low-latitude stations
You can find an output of TayAbsTEC in a directory three which looks like
SITE- name of station
There are two kinds of files in the directory:
DDD here it is a day of year.
SITE_DDD_YYYY.dat you find the following values:
UT- universal time in hours
I_v- absolute vertical TEC in TECU
G_lat- linear longitude and latitude gradients in TECU/°
G_q_lat- quadratic longitude and latitude gradients in TECU/°
G_q_t- linear and quadratic time derivation in TECU/hour
DCB_SITE_DDD_YYYY.datfiles contain DCBs for each satellite (DCB sat) and GPS/GLONASS receiver channel (DCB rec) measured in TECU.
