Base mode
The BASE, power led and selected datalink (UHF, GPRS/GSM or EXTERNAL) will keep lighted.
When satellites fulfill the conditions, the base will enter into the transmit mode and start to
send data through the datalink. The datalink green led flashing every one second means the
base transmit normal. The satellite light will blink according to the number of satellites as
described for static mode.
Rover mode
The ROVER, power led and selected datalink (UHF, GPRS/GSM or EXTERNAL) will keep lighted.
The datalink green led flashing every one second means the rover is receiving data packets. The
satellite light will blink according to the number of satellites as described for static mode.
IV.4 How to measure the antenna height
The height of receiver is 99mm, the diameter is 186mm, the height from the center of the
sealed rubber ring to the bottom is 62mm.
The antenna height is conventionally defined as the vertical height from the phase centre to the
ground surveyed point (the distance “h” in fig. 4.5). It is not possible to measure it directly: you
have to measure other reachable heights (the distances “a”, “d”, “s” in fig.4.5). The distance “a” is
the vertical height from the ground to the mainframe’s bottom, “d” is the vertical height from
the ground to the middle of the rubber ring: both are defined as “vertical heights”. On the
contrary the distance “s” is measured from the ground surveyed point to the middle of the
rubber ring and is called “slant height”. You have to choose the measuring method according to
the used software.
