readgssi.constants
(essentials)
This module contains a number of variables that readgssi needs to perform physics calculations and interpret radar information from DZT files.
Physical constants
c = 299792458
- celerity of electromagnetic waves in a vacuum
Eps_0 = 8.8541878 * 10**(-12)
- epsilon naught, the vacuum permittivity
Mu_0 = 1.257 * 10**(-6)
- mu naught, the vacuum permeability
GSSI constants
MINHEADSIZE = 1024
- minimum DZT file header size in bytes
PAREASIZE = 128
- DZT file fixed info area size in bytes
Dictionaries
UNIT
- dictionary of GSSI field units and associated unit codes
ANT
- dictionary of GSSI antennas and associated antenna codes (read more about these in Antenna code errors)
