Sokkia Radian IS GPS Receiver

L1/L2 Integrated GPS Receiver
SOKKIA’s Radian IS is an integrated, dual-frequency, survey-grade
receiver that can perform both real time kinematic
(RTK) and post-processed surveys. By integrating the receiver, antenna,
memory and batteries into one lightweight
and rugged package, SOKKIA’s Radian IS requires fewer cables. These
features, combined with PAC and Pinwheel
Technologies (patented), provide comprehensive tracking capability with
advanced multipath rejection.

Integrated Design
Integrated, dual-frequency GPS
receiver, Internal Series 700 GPS
antenna (L1/L2) with Pinwheel
Technology (<1 mm phase center
offset and multipath rejection
equivalent to choke ring antenna),
memory and batteries.

Simple Operation
Single-button operation and LED
indicators for battery life, satellite
tracking status, remaining memory
and integer fixed occupation time.

Lightweight & Rugged
Weighs just 1.6 kg (3.5 lb) and
can withstand a pole drop of
2.2 m (7.2 ft)

Unlimited Memory
Removable and upgradeable
Compact Flash card provides
unlimited hours of data collection.

Reliable Power
Ability to hot swap batteries for
continuous surveying.

GPS Technology
PAC technology achieves
centimeter-level accuracy with
RTK corrections, while Pinwheel
technologies decrease errors
associated with multipath
and electromagnetic interference.

Data Collection Software
Built on knowledge from surveyors and previous generations of SDR
electronic fieldbooks, the SDR Level 5 CE
workflow is assembled to follow a logical field collection process.
Provided in one single package, SDR’s full
functionality increases your productivity by offering topographic
surveying, stake out, roading and coordinate
geometry (COGO). Save time with the ability to switch between GPS and
Terrestrial sensors, and ensure quality
of the reading as you check the coverage of collected points using a
graphical view.

SDR Level 5 Features:

  • Full functionality in one package enables you to finish your job
  • Handles
    a large range of GPS and Terrestrial sensors
  • Runs on multiple platforms, including Allegro CX™, JETT•ce®,
    Pocket PC PDAs and many others
  • Map vertical heights with a supplied GEOID file or an inclined
  • Complete any type of surveying, including solar observation
  • Access existing jobs, browse for other jobs, or create a new job
    simultaneously without using a file browser
  • Utilize customizable feature code lists with point-sorting
  • Automatic generation of linework.
  • Ability to export data by a serial port, IRDA connection, modem
    connection or pre-existing file.
  • Customize point code IDs with a range from numeric to alphanumeric
  • Handle data in many forms, including horizontal; horizontal and
    vertical; and horizontal, vertical and X-slope; using COGO or Roading
  • Export data to industry standard formats such as Delimited Text,
    SDR, ICS, MOSS, and SDMS.

Post-Processing Software
SOKKIA’s Spectrum Survey is a comprehensive, easy-to-use, Windows based
software package that supports
all phases of GPS survey operations. SpectrumSurvey Suite combines
Spectrum Survey and Planning into one
software package. This package provides all of the tools you need to
successfully manage your project, from
planning to processing, adjusting and analyzing GPS survey data.

Spectrum Survey Features:

  • Process single and dual-frequency GPS data (code and carrier)
  • An integrated GPS data processing and network adjustment
    environment makes it easy to process and adjust data in a few simple
  • Display data in geographic, state plane, UTM or user-defined
    coordinates. Compute and export data in ground coordinates
  • View and edit baselines before processing, either through menus
    or through the graphical interface
  • Supports commonly used methods of survey data collection,
    including static, rapid-static, kinematic and stop-and-go.
  • Compatible with SOKKIA’s Radian IS, GSR2600 and Stratus GPS
    receivers, along with other proprietary data formats including RINEX.

Integrated GPS System
With a focus on efficiency, SOKKIA’s Radian IS system enables a single
user to complete the toughest task,
saving time and money. Coupled with Spectrum® Survey or SDR Level 5,
the Radian IS system provides
high-accuracy results. With a rugged waterproof and dustproof design,
the system is ideal for a variety of
applications, including topographic mapping, control surveys and
construction staking.

Radian IS System:

  • Integrated receiver, antenna, memory and batteries in one
  • Spectrum® Survey Suite V3 processing and adjustment software
  • Windows® CE data collector and software
  • RTK radio data link
  • GSM connectivity

Post-Processed & RTK Applications:

  • Boundary surveys
  • Construction stake out
  • Create slopes and terraces in landscaping
  • Determine cut and fill for a road project
  • Establish station pairs
  • Geodetic Control points
  • Map utility lines, cables and piping
  • Position aerial photo panels
  • Position aerial towers
  • Plan haul roads, set out blasting patterns or reclamation work
  • Position recording pods
