Other devices included Leica TC1800 electronic tachymeter, a micrometric table, a surveying tripod, three-axis photographic head--Manfrotto 405 Geared Head, geodetic tripod for engineering purposes with a jib, two tribrachs
, two targets and the observation pillar.
The measurements are conducted in the Laboratory on the observation pillar equipped with the tribrach
. By inserting the next plates under the base of the plummet the location of the optic fibre is inclined.
One part originates in the near vicinity of the antenna (pillar/tripod, tribrach
, mounting adapter, station marker, antenna ground plane, etc.), second part comes from more distant reflections.
One part is invoked by the near field of the antenna (pillar/tripod, tribrach
, adapter, marker, ground plane, etc.), second part comes from environment.
The traditional survey tool is a "total station," which is a conventional survey system with an instrument usually referred to as a gun, plus required prisms, poles, tripods, batteries, and tripod-mounted levels called tribrachs
. Until recently, the Army version of this set was the Geodimeter[R] Automated Integrated Survey Instrument (AISI) 444.
