Including all available options
(1)
Accuracy and initialization specications may be affected by
atmospheric conditions, signal multipath, satellite geometry and
corrections availability and quality. Position accuracy specications
are for horizontal positioning. Vertical error is typically < 2 times
horizontal error.
(2)
Performance values assume a minimum of ve satellites and
following the procedures recommended in the product manual.
High multipath areas, high PDOP values and periods of sever
atmospheric conditions may degrade performance.
(3)
Steady state value for baselines < 50 km after sufcient
convergence time.
(4)
No BT or WLAN are used, backlight at default setting (50%
brightness), varies with temperature.
(5)
Optional upgrade to ProMark 220.
