A brief introduction of S9III PLUS
STONEX® devoted itself to offer to surveyors the most advanced GPS tools.
GPS RTK surveying technology plays an important role in surveying tasks and
its use is getting more and more widespread.
As a leading GPS RTK instrument producer, STONEX® guarantees that the
S9III PLUS, our new RTK GPS receiver, is suited for nowadays demands of
precision, reliability and user friendliness.
S9III PLUS is a multi-constellation GNSS receiver, able to receive three GPS
signal frequencies, GLONASS and Compass/Beidou, ready for GALILEO
constellation.
S9III PLUS mainframe integrates a GNSS antenna, GNSS module, UHF
transmitting and receiving radio, radio antenna, GSM/GPRS modem,
Bluetooth device and battery.
So S9III PLUS is totally integrated: it means that the surveyor only needs the
handheld to start its job.
The exquisite outlook and the amazing color bring you a fashioned surveying
station. This device has a higher stability, lesser power consumption, smaller
volume and lighter weight than the previous STONEX® receivers.
S9III PLUS has a special design which makes it waterproof, dustproof and
vibration-proof. The batteries and built-in radio are set in the bottom of
mainframe, giving more effective dustproof and waterproof qualities and
makes the S9III PLUS a better performer in field of surveying. The Wireless
receiver unit (weighs) 1.2 kg: the rover is light and easy to carry. The low power
consumption of receiver allows users to carry out and work in long time with
only one single battery.
Integrated design and anti-jamming property are combined perfectly: the
former avoids the problem of a cumbersome external antenna, and the
mainframe design can resolve the jamming problem effectively.
The S9III PLUS receiver mounts a GPS/GLONASS/BD antenna with a four feed
technology.
This design is able to reduce the electrical phase center error ellipsoid and in
addiction it improves the Right Hand Circular Polarization Characteristics
(RHCP) of the antenna, resulting in enhanced GPS signal tracking and
improved multipath rejection, in case a polarization reversal has taken place
as a result of the signal reflection.
S9III PLUS has a new 3G GPRS/GSM module which allow faster and more
reliable connections.
