General Base Station Setup Rules
and Notes
• Every time the Base Station is setup, a new slant measurement
must be taken since the height of the antenna is different, unless
using a fixed-height tripod, or other permanent mount. If using a
permanent mount, you only need to measure the height of the
antenna once and initialize the Base Station once using
Pocket-3D. The Topcon receiver remembers the initial settings.
However, if any setting stored in the receiver has been changed or
initialized (like a reset function), you need to re-initialize the
Base Station.
• When the receiver tracks a sufficient number of satellites, the
receiver takes only a few seconds to process and report a
successful start. See Chapter 7 if the receiver fails to respond or
fails to initialize.
• Ideally, the Base Station should be placed in an area free of
objects that can obstruct signals from satellites and degrade
positioning accuracy. Obstructions can include trees, buildings,
vehicles, or fences.
• Ideally, the radio antenna should not be placed too close to the
receiver. For large job sites, or sites with hilly terrain, use a tall
tripod or a sturdy structure to raise the radio antenna as high as
possible for better radio transmission range.
