The ring buffer data will be stored on
the chosen memory device in the
following directory:
\DATA\GPS\RINGBUF
The static point which is stored into
the ring buffer has the following point
Id automatically assigned:
RBxxxxff
where:
xxxx - 4 character sensor ID (by
default serial number of the sensor,
last 4 digits)
ff - 2 character ring buffer number
(00, 01 , … 09)
Additional External Devices
The RS500 supports additional
external devices, which may be
required for GPS reference stations
serving special applications. Currently
supported devices are:
• Meteorological Data Sensors
• Paroscientific, Inc.: Met3A
Fan-Aspirated Pressure,
Temperature and Humidity
Sensing System
• Paroscientific, Inc.: Met3
Pressure, Temperature and
Humidity Sensing System
•
Vaisala : PTU200GPS (must
be programmed to mimic
MET3 data string)
•
Tilt Data Sensors
•
Applied Geomechanics, Inc.:
MD900-T Digital/Analog
Clinometer
Data received from all of these
sensor types can be logged along
with the GPS raw data onto the
sensor PC card or internal memory if
installed. The data will be logged
into the same raw measurement files
as the GPS raw data. External
application software such as
ControlStation™ is required to
convert this data to ASCII readable
formats, e.g. RINEX.
It is further possible to directly pass
this data through the sensor and
output it directly via the remote
communication port to the controlling
application software. This is possible
in addition or instead of direct logging
this data internally.
The above external devices can be
connected to Ports 1, 2 or 3 of the
RS500. Specific interface cables are
available from your Leica
Geosystems representative, which
provide power to the external sensors
from the RS500 thus creating a much
neater Reference System installation.
