GAMIT10.71的track模块,使用出现如下错误:
TRACK Version 1.40 GPS Kinematic trajectory program
Running with batch file: track.cmd
DAY and WEEK Options 317 20793
STRING Options
* 32 satellites, at 96 epochs found in igs20793.sp3
Mapped PRNS found: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32
***FATAL** antmod_file command issued before ante_off information for sites
Note: The following floating-point exceptions are signalling: IEEE_DIVIDE_BY_ZERO
STOP TRACK: Use ANTE_OFF command before ANTMOD_FILE
原因是由于,默认的tables下面的track.cmd文件中ante_off参数出现在antmod_file后面了
NOTE: Command MUST be used after obs_file and ante_off commands
to ensure entries for antennas are read.
调整一下顺序就可以正常运行:
track -f track.cmd -d 317 -w 20793
