Firmware GLIDE™
SUPERIOR PASS-TO-PASS
PERFORMANCE IN APPLICATIONS
WHERE RELATIVE POSITIONING IS
CRITICAL
SUPERIOR PASS-TO-PASS PERFORMANCE
NovAtel’s GLIDE technology oers superior pass-to-pass performance for
applications, such as agricultural guidance, where relative positioning is critical. GLIDE
significantly reduces the variation in position error dierences to less than 1 cm
RMS
1,2
from one epoch to the next. GLIDE works in autonomous, DGNSS and SBAS
positioning modes, and is optimized for use in open sky conditions. GLIDE technology
also utilizes GLONASS
3
and BeiDou
3
satellites as well as GPS, when in SBAS positioning
mode, providing better solution availability.
SINGLE-FREQUENCY GLIDE
Our GLIDE technology oers users of autonomous L1 code positioning superior
stability previously available only for dual-frequency carrier phase solutions. GLIDE
combines L1 code and phase data to produce a smooth positioning solution well suited
for applications such as agricultural guidance.
DUAL-FREQUENCY GLIDE
Dual-frequency GLIDE improves the absolute accuracy of the GLIDE position and
creates a robust solution resistant to the eects of high ionospheric activity. Dual-
frequency GLIDE also helps improve the pass-to-pass position performance.
The graphs

on the following page show the dramatic improvement in short term
position stability for a single point solution using dual-frequency GLIDE over the
standard 15 minute time frame for pass-to-pass testing.
1. Typical values. Performance specifications subject to GPS system characteristics, US DOD operational degradation, ionospheric and tropospheric
conditions, satellite geometry, baseline length, multipath eects and the presence of intentional or unintentional interference sources. GLIDE is
optimized for use in open sky conditions and accuracy can vary dependent on changes in satellite visibility.
2. Accuracy specified in RMS. Using dual frequency GLIDE in open sky conditions.
3. When GLONASS and BeiDou option is supported by the receiver firmware model and hardware.

Using the single-frequency GLIDE filter significantly
improves pass-to-pass accuracy without using SBAS
corrections. Using SBAS corrections with GLIDE will
further improve absolute and pass-to-pass accuracy.
Using the dual-frequency GLIDE filter further improves
upon single-frequency GLIDE pass-to-pass accuracy by
better reducing ionospheric errors without the need of
SBAS corrections.
