Local Base Station setup, on Tripod
Local Base Station setup, on Tripod step-by-step
☞ Ensure Satel Radio CCD22 is correctly installed and configured.
1. Setting Up the Equipment
• Set up the tripod, mount and level the CTB102 tribrach onto the tripod.
• Check that the tribrach is correctly centred over the marker.
• Place and lock the GRT246 carrier into the tribrach.
• Screw the CGA100 GNSS antenna onto the carrier.
• Attach the GAD33 arm to the base of the CGA100 GNSS antenna.
• Attach the Gainflex radio antenna to the GAD33 arm.
☞ The GAD32 telescopic rod can be used to increase the antenna height. This will increase the radio signal and therefore the reception of correction signals from a base station or when using a NTRIP solution.
• Check that the tribrach is still correctly positioned and levelled.
• Hang the iCG81 instrument onto a tripod leg.
• Hang the external battery GEB371 onto a tripod leg.
• Use the Antenna cable to connect the GNSS antenna to port
ANT1 on the iCG81.
• Use the second Antenna cable to connect the GAD33 arm to the RADIO port on the iCG81.
• Use the MSC1259 cable to connect the external battery to the P1 port on the iCG81.
• Turn on the instrument.
☞ GSZ4-1 Height hook is needed to measure the Antenna Height later on.
2. Perform a Base Station setup on the iCG81.
