the computing of RTK solution, if a pause on the order of tens of minutes
in RTK data link occured, has been resolved.
A.6 The support of decoding of NMEA-0183 XDR message has been implemented. The
contents of XDR message is available for output via TPS message [XD].
A.7 New options have been added: SEED, _IMU, OMSV, TPBN, TPPM, TPVC, _L2C,
A.8 Antenna database has been updated. New types of antenna have been added

to the troposphere model).
A.24 The parameter for switching between PZ-90 and PZ-90.02 dynamic
constants has been implemented. This parameter is required to maintain
compatibility with previous versions of firmware.
A.25 Datum ID "P90" corresponds to PZ-90.02 datum now. Previous PZ-90 datum
has got "P90-I" designation.

modified.
A.29 Support of mmGPS functionality in EG3 boards has been tuned and modified.
0. Compatibility Notes.
0.1 Starting at the version 3.2, new method for turning the Extended
Information Mode on/off has been supported. It is required to push FN button
three times over the period of three seconds to enable/disable this mode.
0.2 It is not recommended using the parameter "/par/lock/pcode". Use the
parameters "/par/lock/gps/pcode" and "/par/lock/glo/pcode" instead.
0.3 Argument of the parameter "/par/lock/gps/l2c" has been changed. Now it
contains two arguments for turning on/off tracking of CL and CM
signals separately from each other.
0.4 File name conventions for AFRM mode have been changed for Net-G3
receivers: files created at hour boarders have the following names:
XXXXa, XXXXa001, XXXXa002... for interval 00:00:00-00:59:59;
XXXXb, XXXXb001, XXXXb002... for interval 01:00:00-01:59:59 etc.
0.5 TPS message [EN] has been outdated. Use [E3] instead.
0.6 Parameters "/par/ant/inp" and "/par/ant/curinp" are obsolete. Use the
parameters "/par/ant/rcv/inp" and "/par/ant/rcv/curinp" instead.
0.7 The default value of the parameter "/par/lock/notvis" is set to "on" for
G3-based boards (it is a read only parameter for these boards).
0.8 The range of arguments in parameters for locking/using GLONASS satellites
have been changed (parameters "/par/lock/glo/fcn/N" and
"/par/pos/glo/fcn/N"): now N is in the range of -7 - +13 (previous
range was +1 - +24).
0.9 The change in GLONASS datum leads to incompatibility when working with
previous versions of the firmware provided RTCM Message Types
20/21/31/32/34 are in use. In other words, the problem arises when
working in code differential mode or in RTK mode (if Message Types 20/21
are used). It is recommended to upload both the base and
the rover receiver with the same version 3.2. When working with Message
Types 20/21, it is required, also, to change the parameter
"/par/pos/datum/glo/dyn" to maintain compatibility with previous versions.

Type: enumerated
Values: [ int | ext ]
Default: int
Description: Set /query OmniStar antenna input mode:
int - use internal antenna for OmniStar
ext - use external antenna for OmniStar
Note: this command is not supported in the current receivers.
Name: /par/ant/rcv/inp
Access: rw
Type: enumerated
Values: [ int | ext | auto ]
Default: int
Description: Set /query receiver antenna input mode:
int - use internal antenna for receiver;
ext - use external antenna for receiver;

2.2 mmGPS (NBEAM) parameters.
Name: /par/pos/pd/nbeam/id
Access: rw
Type: enumerated
Values: 1 | 2 | 3 | 4 | any | auto
Default: auto
Description: Selection of ID of the transmitter the sensor must work
with. The best one from rms point of view will be selected
if the value is set to ’any’. In this case the receiver will try
to switch the best one. If you choose ’auto’ PZS itself
will try to find ID from present in view according
its own rules. Anytime it is possible to change ’any’ to
’auto’ to acquire signal again if there is any problem with
signal availability.
Do not forget properly set serial port used by PZS with help
of command /par/pos/pd/nbeam/port !
Name: /par/pos/pd/nbeam/any
Access: rw
Type: enumerated
Values: permanent | auto | arrange
Default: permanent
Description: In case of id==any this command instructs receiver what to do in cases:
- dissapering laser signal because of e.g. shading;
- unsuccessful switching to the best transmitter;
Value ’permanent’ instructs receiver try to continue acquiring signal up
to success. ’auto’ instructs PZS to try to find ID from
present in view according its own rules. ’arrange’ instructs
receiver to arrange all enabled IDs according rms and to try
consecutively catch one from available
Name: /par/pos/pd/nbeam/wait
Access: rw
Type: list {float t1, float t2}
Values: {0.099...60 , 0.099...60}
Default: {4.,60.}
Description: t1 defines time interval in seconds how long it is necessary
to waiting for choosed signal acquiring in cases of dissapering signal
and unsuccessful switching for values any==auto or
any==arrange. t2 defines how long it is necessary to work with
found signal. After t2 passing away the receiver will try to
acquire the best ID again.
Name: /par/pos/pd/nbeam/bridging
Access: rw
Type: boolean
Values: on | off
Default: off
Description: Setting this parameter to ’on’ instructs receiver to bridge
(to compensate jump) mmGPS height estimation at ID
changing. If you choose ’on’ be sure there is not considerable
changing of height during laser signal absence
Name: /par/pos/pd/nbeam/type
Access: rw
Type: enumerated
Values: const | dissap
Default: const
Description: This parameter defines type of bridging. Value ’const’ means the
compensation is distributed uniformly (constantly) over all zone where you
works with current ID. This type is recommended only for case
compact site (non-stretched) and when height installation /
initialization error of transmitter is dominant source of
error. Value ’dissap’ means a jump is instantaneously
compensated but then height estimation is slowly returning
back to original level (compensation is
dissapearing). Dissapering process has linear behaivour and
distibuted over zone with radius equal to double distance
between receiver and transmitter in moment of ID
changing. This type allow to avoid accumulation of error as
sqrt(N)*sigma where N- is total number of used transmitter
along path; sigma - standard deviation of error of single
transmitter. With help of this technique it is possible to
provide standard deviation of just sigma between design (project)
profile and measured by mmGPS. This technique is recommended
for stretched site (e.g. road work) when number N is large
enough (N>10) and when dominant error is either:
- horizontal installation/initialization error of transmitter
- thermal variation of self leveling mechanism of transmitter (wrong level calibration)
- strong beam refraction at long distances
- strong beam nonlinearity at long distances
- any other effect with non constant yield over distance
