Introduction
This document is user guide for S900A and it is intended to introduce how to
use the receiver correctly.
S900A GNSS receiver is a multiple-frequency receiver and designed for GNSS
surveying applications. It is available as a base station, or as a standalone rover,
which can be switched freely whenever and wherever, offering maximum
versatility in the system configuration to meet your specific requirements. At
the same time, S900A receiver can upgrade easily to continually meet your
new demand.
The integrated design of the receiver makes the S900A only 1.3 kg, which is
light and portable. The internal antenna supports the all satellite system
signals like Beidou, GPS, GLONASS, Galileo, QZSS, IRNSS. The users no longer
have to worry about upgrading RTK hardware to support other satellite
systems.
The internal use of the latest Sensor Fusion system allows the field to take the
tilt measurement without calibration, and the field surveying is more
convenient.
An important feature inside S900A is Atlas reception: Atlas is a differential
corrections systems broadcasted on L-Band, allowing increase in position
accuracy in area not covered by conventional CORS working under Ntrip
Technology (lack of reference stations, lack of GPRS signals, etc). Atlas is
broadcasted by satellite systems, so the reception is nearly ensured all over
the world. Atlas uses similar technology compared to SBAS, but providing
better positioning accuracy.
The new S900A has the new GSM modem. Worldwide LTE, UMTS/HSPA+ and
GSM/GPRS/EDGE coverage Multi-constellation GNSS receiver available for
applications requiring fast and accurate fixes in any environment. EG25-G is
backward-compatible with existing EDGE and GSM/GPRS networks, ensuring
that it can be connected even in remote areas devoid of 4G or 3G coverage.

3.4 Receiver self-check
Self-check functionality is to check whether every module works normally.
When S900A receiver has indicators off or module doesn’t work normally, you
can use self-check to inspect the receiver. S900A self-check consists of six
parts, namely GNSS, radio, network, WIFI, Bluetooth, and sensor. The self-
check results will be voice broadcasted in the process. Self-check operation
and result broadcast are as followed:

Stonex S900A GNSS Receiver – User Manual 15
When receiver is powered on, press power button and hold it until the receiver
voice broadcasts “power off”. Press it again until the receiver sounds a beep
and voice broadcasts “self-check”, which means the receiver starts to operate
self-check. New receiver is recommended to operate self-check at least once.
In the process of self-check, each module inspection is followed by its
inspection result. If the module inspection passes, it will voice broadcast “OK”
and module led keeps on until the whole self-check finishes. If the module
inspection fails, it will voice broadcast current module inspection fail, keep
module led flashing and buzzer sounding until you restart the receiver. Self-
check lasts for about 1 minute. If there is self-check failure, please contact local
dealer.
If every module indicator is lit with no flashing, and voice broadcast says every
module work normally (such as “GPS self-check. OK.”), it means all the modules
work normally. Receiver starts to work after the whole self-check finishes
3.5 Insert cards

4. New IMU Technology
The New S900 series receivers are equipped with the new IMU1 System that
allows tilted measurement (TILT).
It has the following advantages:
 The initialization process is much simpler.
You can use Stonex Cube-a field software to calibrate the sensor; Cube-
a will ask to initialize the IMU when needed and it will show how to do
it. The process is very fast, usually a few seconds for IMU initialization.
 The receiver with integrated inertial navigation module ensures the real-
time interference-free tilt compensation.
It’s not affected by any geomagnetic and external metal structures and
other environmental influences. It adopts "satellite and inertial
navigation" dual inspection.
 Fast and precise survey.
It’s possible survey and store points with just one measure with slant pole
up to 60° (2 cm accuracy up to 30°, 5 cm accuracy up to 60°).

4.1.1 Sensor Activation and Configuration
To use the S900A with new IMU technology it’s necessary to enable the feature
in the specific options menu.
Before using the receiver to collect points with the slanted pole, check if the
pole tilt correction functionality has been enabled.
With Stonex Cube-a, follow this path to find the configuration menu:
Configure  System Settings  Sensor Options.
There, enable the Pole Tilt Correction.

Stonex S900A GNSS Receiver – User Manual 19
In the same screen, it is possible to ask the software to show on screen the
angle of the tilt angle (in decimal degrees, 0° = true vertical).
To show this information, mark the relative check inside the Sensor Option
menu.
The user can also define the verticality tolerance of the instrument.
That is, the maximum value of the (sensor) tilt angle that the software shall
accept when checking for the pole verticality.
The value is in decimal degrees.
Example: 0.3 means +/- 0.3° from true (local) verticality.
