The GPS L1 carrier has a wavelength of 19 cm which is much smaller than the 100 m
chip length of the modulated C/A (”Clear Access”) pseudo--random noise code used for
GPS satellite positioning. Thus, obstacles of correspondingly small size disturb the
heading determination process. The satellite compass is much more susceptible to ob-
stacles than a satellite positioning receiver.
Consequently, extreme care is required when installing the STD 21 Antenna Unit. Proper
operation is only effective if the installation requirements detailed in Chapter 3.2 ”In-
stallation of the Antenna Unit” have been met!
