Slope Measurement Type; Vertical Measurement Type; Receiver Setup: Pps And Event In; Background Information - Leica GR30 Online Help Manual

HO = Horizontal Offset
VO = Vertical Offset
VR = Vertical Height Reading
VE1 = Vertical Phase Center Offset for L1
VE2 = Vertical Phase Center Offset for L2
BPA = Physical Reference Plane (bottom of pre-amplifier)
ARP = Antenna Reference Point. Intersection of the BPA horizontal plane and the vertical symmetry axis.
SR = Slope Height Reading

Slope measurement type

Note: If the Offset Point on the antenna is above the Physical Reference Plane BPA, the Vertical Offset VO is negative!

Vertical measurement type

Antenna Height = VR + VO

Receiver setup: PPS and Event In

Background Information

PPS
PPS stands for pulse per second. If configured, the receiver sends out an electric pulse at a specified interval time. This can be used
e.g. to activate another device. The pulse is sent out via the dedicated PPS port. For further information go to Ports & Pins
Assignments: GR25.
Event Input
Event input is possible via serial port 2. The event input interface allows for the detection of pulses which are sent from external devices
connected to the receiver. The pulses can be recorded in the receiver and then later can be superimposed on the processed kinematic
data. The positions where the events took place can be interpolated in LGO.
Events logged during real time operation can also be exported to an ASCII file using an appropriate format file.

Info to log
Description
Check to activate the output of a periodic pulse, uncheck to deactivate.
Select the rate at which pulses are to be output. Ranges from 0.05s to 20.0s.
Select to output a pulse starting with a rising or a falling edge.
Rising edge: Generates a normally low, active high pulse with the rising edge as the
reference.
Falling edge: Generates a normally high, active low pulse with the falling edge as
the reference.
Description
Activates the detection and logging of events being received on serial port 2.
