Hexagon Veripos LD8 - 4.8.9 Setting PPS via terminal; 4.8.10 Enabling RAIM Mode via terminal; 4.8.11 Enabling Veripos RTCM output via terminal

4.8 Output configuration
4.8.9 Setting PPS via terminal
The LD8 allows for the PPS polarity to be configured and set to an increase in pulse from 0v (POSITIVE)
or a decrease in pulse to 0v (NEGATIVE). The pulse has a width of 2000 microseconds.
An example of the PPSCONTROL command is given below which shows the pulse being set to
POSITIVE:
PPSCONTROL ENABLE POSITIVE
PPS output can be disabled by sending the following:
PPSCONTROL DISABLE
4.8.10 Enabling RAIM Mode via terminal
Receiver autonomous integrity monitoring (RAIM) is a technology developed to assess the integrity of
GNSS signals used by a GNSS receiver. RAIM uses redundant signals and a statistical function to
determine if there are problems with the positioning solution; in simple terms, RAIM acts as an internal
self-check. RAIM is enabled by default.
High Ionospheric activity may cause problems with the RAIM algorithm; only in this scenario and with
consultation and guidance from Veripos Support should users disable RAIM. RAIM should be enabled
once conditions return to normal.
RAIM Mode can be enabled by sending the following:
RAIMMODE VERIPOS RAIM ON
RAIM Mode can be disabled by sending the following:
RAIMMODE VERIPOS RAIM OFF
4.8.11 Enabling Veripos RTCM output via terminal
RTCM can be output on any of the LD8 serial COM ports. Within the terminal window enter the
commands below where updating COM1 with the desired output COM port number.
UNLOGALL COM1
INTERFACEMODE COM1 NONE RTCM OFF
LOG COM1 VERIPOSRAWRTCMDATAB ONNEW
To change the baud rate of the serial port, send command below. COM should be the same COM port as
used in the initial step and the field 9600 replaced with the appropriate baud rate.
