Using SP90m With Two Antennas
The reader is supposed to know how to run the Web Server
(see
Getting Started With the Web Server on page 47 ), and
how to use the receiver user interface (see Receiver User
Interface on page 26 ) before reading this section.
Remember, when using the Web Server, at any time you can
access context-sensitive help by pressing this key:
Specifying the
Models of
Antennas Used
When using SP90m with two GNSS antennas, both GNSS
input #1 and GNSS input #2 are used.
The setting described below is required prior to configuring
the receiver in any of the operating modes described in the
sections that follow.
Use the Web Server to specify the models of antennas
connected to input #1 and input #2:
• Go to
Receiver
>
Position
>
Sensors/Antennas Setup
.
• Set
Multi-Sensor Mode
to
Two Antennas
or
Two Antennas (L1
only on input#2)
depending on the reception capability of
the model of antenna you connect to input #2.
• Choose the point on the antenna for which you want the
SP90m to compute the position (L1 phase center, ARP or
ground mark).
• For each of the two antennas (primary and secondary
antennas), describe the model and height of antenna
used:
– Manufacturer
– Antenna name and its RINEX name
– Method used to measure the antenna height (i.e.
choice of the point on the antenna from which the
height measurement is performed)
– Value of measured height according to the chosen
antenna measurement method.
NOTE 1: Entering the height only makes sense if you want
to get the position of the ground mark.
NOTE 2: Antenna heights are not required when
computing heading.
• Press
Configure
. The two antenna models are now set.
NOTE: When configuring a static base from the front panel,
you will be able to select the antenna model used for the
