Positioning
ANTOISE 2
The ANTOISE 2 set allows you to measure the position of the work to be carried out with an accuracy of 3 cm, as well as its inclination and orientation.
It consists of two GPS receivers, a GPS receiver called “base” placed above a point of known and exact coordinates.
It corrects the measurement of a second mobile receiver, the “machine” GPS receiver. It is composed of a metal support of one meter equipped with 2 GPS antennas and a housing containing the calculation unit.
One of the antennas is the positioning reference antenna, the other is used to determine the orientation
NORMA 2
The NORMA2 accurately measures the orientation and inclination of the mast on which it is mounted.
It is an efficient aid for Kelly piles, auger cast piles and mine or quarry parameters. It enables an accurate inclination and drilling direction control, independently of the positioning of the machine.
No effort or additional calculation is required, the driller controls the positioning of the mast on the X and Y axes on the screen of DIALOG MX4.
