epoch 50 GnSS System
1 Accuracy and reliability may be subject to anomalies due to
multipath, obstructions, satellite geometry, and atmospheric
conditions. The specifications stated recommend the use of stable
mounts in an open sky view, EMI and multipath clean environment,
optimal GNSS constellation configurations, along with the use of
survey practices that are generally accepted for performing the
highest-order surveys for the applicable application including
occupation times appropriate for baseline length. Baselines longer
than 30 km require precise ephemeris and occupations up to 24 hr
may be required to achieve the high accuracy static specification.
2 May be affected by atmospheric conditions, signal
multimath,obstruction, and satellite geometry.Initialization reliabilityis
continuously monitored to ensure the highest quality.
3 Depends on SBAS (WAAS/EGNOS) system performance.
4 Below –20°C, external power must be used.
5 Three batteries supplied standard.
6 When used with Survey Pro, only 1 Hz and 5 Hz modes are
supported.
7 Not all protocols will work with all radio baud rates and channel
spacing.
