Abstract: A satellite navigation device 110 including a receiver having an adjustable code generator is described. The adjustable code generator is configurable to generate a set of spread-spectrum code signals. Each spread-spectrum code signal has a respective length corresponding to a repetition period. The set of spread-spectrum code signals includes first and second spread-spectrum code signals having distinct first and second lengths.
