Setting a Base With a Radio Transmitter
This page is an abridged version of the Base Setup-Full Setup page only showing the settings required to configure a base with the internal or an external radio transmitter.
These groups of parameters are detailed below.
Base
Use this area to enter the position of the base.
Parameter |
Designation |
$PASHS |
Dynamic |
Necessarily static. |
DYN |
Station ID |
Choose and enter a station ID for your reference station, according to the type of differential messages it will generate: • 0-1023 (RTCM 2.3) • 0-4095 (RTCM 3.x and ATOM) • 0-31 (CMR & CMR+) |
STI |
“Get current position” button |
Click on this button if you want to allocate the last position computed by the receiver as the reference position for the base. As a result, the Lat/Lon/Height fields below are updated with the coordinates of this last computed position. |
CPD,MOD |
Latitude Longitude Ellipsoid Height |
Latitude, longitude and ellipsoidal height defining the reference position of the base. May be entered manually or using the “Get Current position” button. |
POS |
Antenna
Use this area to define the parameters of the antenna used physically at the base, as well as a virtual antenna if necessary. A virtual antenna may be defined to allow the base to deliver raw data as if it were collected with this antenna.
See the description of each parameter in the table below.
Parameter |
Designation |
$PASHS |
Reference Position |
Select one of the options below to define the physical location of the base: • L1 phase center • Antenna Reference Point (ARP) • Ground mark |
ANR |
Measurement Type |
Specify the type of measurement (“Slant” or “Vertical”) through which the above antenna height was measured. |
ANH |
Antenna Height |
Enter the measured antenna height according to the measurement type used and the selected distance unit. |
ANT or ANH |
Receiver antenna |
Select the name of the antenna used at the base. This antenna name can only be chosen from a list of antenna names stored in the receiver. UNKNOWN, NULLANTENNA, ADVNULLANTENNA are special definitions of antennas typically used as virtual antennas. |
ANP,OWN |
Antenna Radius |
(Only if “Slant Height” measurement type selected). Enter the antenna radius according to the selected distance unit. |
ANT |
SHMP Offset |
(Only if “Slant Height” measurement type selected). Enter the vertical offset of the Slant Height Measurement Point for the antenna used by the rover. Take care to enter this parameter in the selected distance unit. See also the Note below. |
ANT |
Virtual Antenna |
This parameter allows you to define a virtual antenna: • Select “Off” if you do not want to define one • If you want one, select the virtual antenna name for which you would like the receiver to deliver raw data, i.e. as if the raw data had been collected using this antenna. This antenna name can only be chosen from a list of antenna names stored in the receiver. NULLANTENNA, ADVNULLANTENNA, etc. are the most commonly used virtual antennas. |
ANP,OUT |
Satellites
Use this area to define the constellations tracked by the base as well as the elevation mask applied to all constellations. See the description of each parameter in the table below.
Parameter |
Designation |
$PASHS |
Recording and Output Elevation Mask |
Enter the elevation mask, in degrees, used by the receiver to determine which raw/differential data from each visible satellite should be recorded or output, depending on the elevation of the satellite. No data from any visible satellite located below this elevation angle will be recorded or output. |
ELM |
GLONASS |
Check this button to enable GLONASS tracking (requires installed S option). Clear it otherwise. |
GLO |
SBAS |
Check this button to enable SBAS tracking. Clear it otherwise. |
SBA |
Transmitter
Use this area to set the receiver port to which the radio transmitter is connected, declare the type of radio used and enter its settings.
Parameter |
Designation |
$PASHS |
Message |
Choose the type of differential message that will be broadcast by the transmitter. The detail of the selected message appears next to the field. |
BAS |
Device |
Select the model of the radio used: • None/Cable • U-Link TRx • Magellan UHF: Radio transmitter P/N 800986 • PDL HPB/LPB • ARF7474B EU: License-free radio for use in Europe • ARF7474A NA: License-free radio for use in North America • ADL Vantage • ADL Foundation |
RDP,TYP |
Following the selection of a radio type, new fields appear after and just underneath the Device field showing the required settings for the transmitter. The table below lists the possible choices for each setting, depending on the selected radio.

• NA: Not Applicable.
• Possible choices for air link speed depend on channel spacing and protocol used.
• Using the Load Transmitter Settings button: When this button is made visible at the bottom of the web page, first click on it to read the current settings of the chosen radio type (“Loading..” is displayed in the Channel field while these settings are being sent for your reading). (Using this button is equivalent to using the $PASHQ,RDP,PAR command.) As a result, the relevant fields are refreshed to view the current radio settings.
• Relevant $PASHS command for all radio parameters: RDP,PAR.
