Trimble R8 GPS Antenna

Trimble R8 GPS Antenna Receiver


The Trimble® R8 GPS system combines industry-leading GPS receiver
technology with numerous innovative features designed to improve
performance and productivity in the field.
Trimble R8 is a 24-channel, dual-frequency GPS receiver, GPS antenna,
and data-link radio combined in one compact unit weighing just 1.3 kg
(2.9 lb).

Trimble R8 is designed to deliver high-quality tracking and
performance. Using less than 2.5 W of power, advanced Trimble R-Track
technology ensures optimal tracking even in hostile GPS environments.
And with the introduction of new L2C signals, which are part of GPS
modernization, Trimble R8 will use these signals to provide even more
robust tracking. The patented four-point antenna feed of the system’s
built-in dual-frequency receiver provides sub-millimeter phase-center
stability for maximum precision. The system includes built-in WAAS and
EGNOS capability, providing real-time differential positioning without
a base station.

Trimble R8 offers the option of upgrading the internal 450 MHz radio
with transmitting capability, making a 100%-cable-free base station a
reality. External radios, cables, and extra tripods are no longer
required, so setup and operation is incredibly simple and efficient.
Save time and significantly increase productivity as a result.
Trimble R8 GPS systems with this internal radio option are now
completely interchangeable as base stations and rovers. Standardize on
Trimble R8 and use it as a base station or rover as each survey
demands. Trimble R8 increases your flexibility on the job. The internal
radio’s transmission range is 3–5 km. For greater range, simply use one
of Trimble’s external radios as a repeater.

The Trimble R8 GPS system’s performance as a rover is unsurpassed in
the surveying industry. On the rover pole, Trimble R8 with a Trimble
controller weighs just 3.6 kg (7.9 lb). Experience less fatigue thanks
to the rover’s ergonomic design and light weight. Bluetooth® wireless
communication between the receiver and controller makes the rover 100%
cable free for your convenience. With Trimble R8 you can choose the
communication option that best suits your needs. Use the 450 MHz
internal radio option for receiving corrections from a local base
station. Alternatively, choose a built-in GSM module for mobile phone
communication. A Trimble R8 rover will work as long and as hard as you
do. Extremely low power consumption lets you run the Trimble R8 rover
for longer without changing batteries. A large internal memory of 6 MB
lets you conveniently log static or kinematic data for postprocessing.
Trimble R8 is also rugged enough for any job. It will withstand a pole
drop of up to 2 m (6 ft) onto a hard surface, and is even submersible
to 1 m (3 ft).
