RTK Surveying Preliminary Steps
RTK Base Setup
• You will need a tripod and a tribrach (not provided) to
install the base. The provided antenna extension pole
fitted with a 5/8” male adapter is also required in this
configuration.
• For a long-range radio link, i.e. more than 1 mile or 1.6
km, for which the radio antenna should be placed as high
as possible, it is good practice to install the antenna on
top of an antenna pole secured on a tripod (neither of
these items is provided).
• To power the radio, you need an external 9-16 V DC power
source. Using a standard 12-V DC battery is a convenient
choice. In this configuration, the ProMark 800 can be
powered either from the same power source
(recommended), using cable P/N 802143, or from its
internal battery.
Powering the ProMark 800 from the external battery offers
two advantages:
1. Operating sessions can be extended significantly.
2. The external battery operates as a trickle charger for
the ProMark 800’s internal battery.
