3.5 GLIDE
NovAtel’s GLIDE
®
is a positioning algorithm for single-frequency GPS and GPS/GLONASS applications.
GLIDE produces a smooth position output tuned for applications where time relative accuracy (pass-to-pass) is
more important than absolute accuracy. Because of this, it is well suited for agricultural applications.
Multipath signals tend to induce time varying biases and increase the measurement noise on the L1/L2 pseu-
dorange measurements. Carrier phase measurements are much less susceptible to the effects of multipath. The
GLIDE algorithm fuses the information from the L1 code and the L1 phase measurements into a Position Velo-
city Time (PVT) solution.
GLIDE includes settings for a dynamic mode, a static mode and an “auto” mode, where the filtering parameters
are automatically adjusted as vehicle velocity varies between stationary and dynamic states.
