BINEX is a data format
designed by UNAVCO. It defines
several method for encoding binary information with an emphasis on how
to handle GNSS-related data. The NetRS can be configured to stream
Binex formatted data containing GPS observables and related data.
(Similarly formatted Binex data can be recorded in internal data files,
as described in the Data Logging
description.)
The Binex streaming service can be
configured on any type of port (Serial, UDP, TCP or REP). The
configuration setup page provides several options for which Binex record
types are included, the rates of those records, and the exact contents
of the records.
GPS observables data can be sent, based on one of several
different epoch intervals, or suppressed altogether by setting the
Interval to "Off". The observables have several options:
- Carrier phase measurements (in either type 0x7f-02 or type 0x7f-03
records) can be smoothed or unsmoothed.
- Observables can be encoded as either types 0x7f-02 or 0x7f-03,
or BOTH. (Sending both is useful for comparison of the newer
type 0x7f-03 with the older style 0x7f-02 in the same stream.) Note
that type 0x7f-02 has no other options while type 0x7f-03 has
several degrees of flexibility.
- Type 0x7f-03 records can optionally include L1-C/A code Doppler
frequencies for each satellite.
- Type 0x7f-03 records can optionally include Cycle Slip counter
information for each satellite.
- Type 0x7f-03 records can optionally include the receiver
clock offset information. This can be included in every
0x7f-03 record, or ONLY in those in which a millisecond clock
rollover adjustment was made.
A System Status Record (type 0x7d-00) can be saved at specified
intervals. The record will contain the NetRS internal temperature and
readings of the power source voltages.
MetaData Records (type 0x00) can be saved at specified intervals.
These records can optionally contain several different fields.
- Site Description - Field Identifer 0x04
The string entered in the Reference Station Setup
Description field.
- Station ID - Field Identifer 0x0f
The 4 character string entered in the Reference Station Setup
Binex Station ID field.
- Receiver Type - Field Identifer 0x19
This will always indicate "TRIMBLE NetRS".
- Rinex Receiver Number - Field Identifer 0x1a
This will be the ten digit NetRS serial number.
- Firmware Version - Field Identifer 0x1b
This will be a string of the form '1.1-0,18/AUG/2004'.
- Antenna XYZ - Field identifer 0x1d
This is the most recently calculated position in the WGS-84
coordinate system.
- Antenna Offset - Field Identifer 0x1f
This field contains the offset (in East, North and Up) of the
Antenna Phase Center (APC) from the reference position. The values
include the Height field entered from the Antenna Configuration
page, as well as the APC characteristics of the antenna.
- Rinex Antenna Number - Field Identifer 0x18
This value is Text Antenna Serial Number as entered on the
Antenna Configuration page. If that value is blank, then the
Numeric Antenna Serial number will be used instead.
