Single Point Positioning

With either the external GNSS antenna or only the built-in antenna, Geosun eFix R2 series
can be used alone for single-point dynamic positioning, and the positioning accuracy can
reach decimeter level as the best. Furthermore, decimeter and even centimeter accuracy can
be achieved by post-processing software Caravel PP.

Caravel PP is high-precision GNSS post-processing positioning and velocity determination
software developed by Geosun. It can provide dynamic/static differential positioning and
dynamic/static precise single-point positioning. With the global advanced proprietary
single-epoch ambiguity resolution algorithm, as well as several exclusive core technologies,
Caravel PP has been proven to be preeminent and robust in various applications.

Wide Area Differential

Wide area differential means to get precise positioning by satellite broadcast system and the
GPS correction data provided by ground stations. Geosun eFix R2 series can receive
wide-area differential signals. By differential technology it can provide the decimeter level
high-precision coordinate data without purchasing additional equipment or paying any fee.

CORS Differential

CORS (Continuously Operating Reference Station) is a continuous-running network system
of base stations, strategically located throughout participating states, applying technologies
of modern computers, data communication and internet (LAN / WAN) to provide different
types of exact GPS observations (carrier phase, pseudo-range), various correction data,
status information, and other related GPS services in real time to different types and
different level of users with different needs.

With this technology, eFix R2 series handheld can carry out long-distance RTK surveying
with centimeter-level accuracy.

In the CORS system, eFix R2 series handheld operation diagram is as below:

eFix R2 Series Hardware Operating Instructions

46

RTK Positioning

Post-processing is needed in traditional GPS surveying, such as static, rapid static and
dynamic surveying, to get centimeter-level accuracy. But Geosun eFix R2 series system is
able to obtain real-time centimeter-level positioning accuracy in the field. With the carrier
phase dynamic real-time differential (Real-Time Kinematic) technology, eFix R2 series
brings new working methods for the construction stakeout, topographic mapping, various
control surveying and etc., and greatly improves the fieldwork efficiency.

Geosun eFix R2 series RTK system is composed of at least two R2 series handhelds. One is
used as base station while another or the others is (are) as rover (s). The base receiver and
the rover receiver are exchangeable.

Using eFix R2 series for RTK survey, the differential data link can be by either UHF radio
or GPRS/3G (WCDMA) (through such as GS server). For the latter, users only need to
purchase an ordinary phone card (SIM card), then connect to GS Server through the GPRS
network link to achieve data communication, which method is very simple and inexpensive.

Operation Mode and Configuration

47

Setting up Base Station

Base station can be mounted on a known point or unknown points. (Note: If you want to
use the conversion parameters calculated before, the location of the base station should be
the same with the last site. Open the project built last time, set up the base station, and then
you just need to modify the base station antenna height and make sure the base station is
transmitting differential signals. The rover can work directly without calculating the
conversion parameters.)

The location of base station must meet the following requirements:

 Open environment, no large shelter objects above 15 degrees elevation mask angle;
 No electromagnetic interference (No microwave stations, radar stations, cell phone

signal stations and etc. within 200 meters, and no high-voltage lines within 50
meters);

 Away from terrain and ground objects that reflect electromagnetic signals strongly,

such as high-rise building, water area and so on.

 In radio working mode, the base station should be set up at a high place and there

shouldn’t be large shelter objects between base station and rover.

 At least two known points (The known point can be coordinates of any coordinate

system. To check the correctness of the known points, three or more known points are
needed.)

The basic operations to set up base station are as follows:

1. Set up the tripod.

2. Install the GNSS antenna on the tripod.

3. Fix the base station handheld. First fix the tripod handheld bracket on the tripod, then

put the handheld into the bracket; tighten it, as shown below.

eFix R2 Series Hardware Operating Instructions

48

4. Connect the external GNSS antenna to handheld

Connect the external GNSS antenna to handheld by external antenna connecting cable, as
shown below.

When the antenna is connected, the base station setup of GPRS/3G communication mode is
done, as shown below.

Base Station (GPRS/3G Mode)

5. Install the transmitting radio

If radio communication mode is required, you need to install the external transmitting radio.
The radio transmitting antenna set up on a tripod should be placed on a high place. And
there should be at least three meters far between the handheld tripod and the transmitting
radio antenna.

After installing the transmitting radio antenna, fix the transmitting radio on the tripod, then
connect transmitting radio and lead-acid battery by the transmitting radio power cable, then
connect transmitting radio and handheld by the transmitting radio communication cable.
The base station in radio communication mode is done and shown as below.

Post-Differential Dynamic Positioning

For areas where real-time communication is difficult between base station and rover,
high-precision differential dynamic positioning can be realized by post-processing. In this
work mode, base and rover just need to save the fieldwork observation data. After back to
the office, using Geosun Caravel PP software to process the data, you can get the
centimeter-level accuracy differential positioning results.

1. The RF power switch of transmitting radio selects high power output in the HIGH

position while the action range is within 8km, selects low power output in the LOW
position while the action range is within 3km.

2. The input voltage range of PDL transmitting radio and receiving radio: 10.5V - 16V,

and the standard input voltage is 12V.

3.

The PDL enclosure is rugged extruded aluminum with integrated heat sink fins. The
enclosure is painted with weather resistant powder coat blue paint. Black bumpers are
integrated with front and rear gaskets to provide shock protection and watertight
operation. The enclosure is not designed to withstand submersion and must not be
allowed to sit in standing water.

4. The PDL enclosure and heat sink may become very hot during operation. This is

normal depending on the ambient temperature, RF power selection and transmission
duty cycle. Turn off the unit and allow it to cool prior to handling.

5. In the receiving radio has a built-in charger that monitors and controls the charging of

the internal battery. The internal battery quickly charges in less than 4 hours, and can
be charged with the supplied charger, or from an external 12 volt supply. We
recommend charging the internal battery at room temperature. Charging is inhibited if
the ambient temperature is below 0° C or above 40° C.
