gps_smask
Mask specifying types of packages from
which data has been obtained
gps_sig
GPS quality indicator (0 = Invalid; 1 =
Fix; 2 = Differential, 3 = Sensitive)
gps_fix
Operating mode, used for navigation (1
= Fix not available; 2 = 2D; 3 = 3D)
These measurement labels are arrays, where the indexed element points to the
same satellite (E.g. gps_info_satsigstrength[3] tells the receiving signal strength
of satellite 3. Satellite 3 has the SAT‐ID given in gps_info_satid[3]).
