The Initialisation of the Base station is done with the GPS > Start Base submenu or the button shown above.
In this menu you can enter the name of the reference station (PntNo.), the plane coordinates of the reference point, the antenna height, the elevation mask and the radio-port.
Furthermore for TPS-receivers the maximal number of used satellites can be chosen and the Multipath-Reduction can be activated. Therefore the Base- and the Rover-receiver need to have the necessary option. The multipath settings should be the same for base and rover receiver. To send out Base corrections over multiple radio ports the Multi-Base check box needs to be activated.
The button <Nav.Sol.> reads a position from the navigation solution of the receiver if the receiver tracks four or more satellites. The button <Satellites> shows the available satellites if GART-2000® CE is able to establish a connection to the GPS receiver. After having done all settings the button <OK> initialises the Base receiver and saves the reference coordinates.
The button >> next to the field Ant.Height opens the submenu for the Antenna Height. Choose the manufactory and the antenna type. For each antenna type the individual antenna offsets are shown.
Enter the type of antenna height measurement:
- instrument height: measured from the marker to the bottom of the antenna at the base of the mounting threads,
- slope: measured from the marker to the lower edge of the groove around the antenna at the seam between the top and bottom halves of the antenna casing.
In the field Measured enter your slope or vertical antenna height. The true vertical height will be calculated immediately and will be shown in the field Calc (TV). After terminating this window with the <OK> button, the true vertical height will be set as antenna height in the measurement window. The button <Save> is only needed to store additional antenna types.
The true vertical antenna height in GART-2000® CE accounts for different antenna offsets in case different antenna types are used on base and rover. In addition to the predefined antenna types in the list; you may enter your own antenna types. To do so enter a new name for your antenna and edit the values in the offset fields. The button <Save> stores the new entry.
