SPS855 features

This receiver is ideal for contractors who operate mid-to-large size projects with machine control.

This receiver is also suitable for system integrators. It can accept site calibration data and user-defined geoid and then output site coordinates.

The receiver has the following features:

• Integrated GNSS receiver and radio

• The following options and upgrades are available for this receiver:

  • Location RTK

  • Location RTK with Precise Vertical

  • Precision RTK base

  • Precision RTK rover

  • Precision RTK base and rover

  • Moving Base/Heading

  • GLONASS

  • Galileo

  • BeiDou

  • Data logging (32 MB)

  • 2 watt output for interval 450 UHF radio

  • 1PPS (Construction version only); it is standard on the Marine version

  • Trimble xFill™ RTK service is available as a one-time purchase option for rover systems with the SPS855 modular receiver.

• 450 MHz (403 MHz to 473 MHz) or 900 MHz internal radio. The 450 UHF is a wideband 403 MHz to 473 MHz radio.

• Supports the SNM941 cellular modem

• Upgradeable receiver from Location GPS to Precision RTK modes. The modes are:

  • Location GPS precision at sub meter

  • Location RTK precision of 10 cm horizontal and 10 cm vertical

  • Location RTK precision of 10 cm horizontal and 2 cm vertical

• Precision RTK mode for highest 3D accuracy. Optional Base only, Rover only, or Base/Rover modes.

• 440-channel L1/L2C/L5 GPS and QZSS plus L1/L2 GLONASS receiver, Galileo, BeiDou

• Trimble CenterPoint® RTX and OmniSTAR XP/HP/VBS service capable

• 4-channel WAAS (Wide Area Augmentation System), EGNOS (European Geo-Stationary Navigation System), and MSAS Satellite Based Augmentation (SBAS) compatible

• Long-life integrated battery, typically provides 9 hours operation as a base station or 12 hours operation as a rover with internal transmit/receive radio

• Configuration and monitoring interface through the following methods:

  • Web interface

  • Networked or peer-to-peer Ethernet

  • Integrated display and keyboard

  • Trimble Siteworks™ or SCS900 Site Controller software

• Choice of external GNSS antenna for base station or rover receiver operation. See GNSS antenna chart.

• Small, lightweight design – 1.65 kg (3.64 lbs) receiver only, including the battery; 4 kg (8.82 lbs) complete system weight (rover including controller and rod)

• Permanent/semi-permanent and mobile quick setup base station capability

• Backpack, belt, rod, truck, and marine vessel mounting options for rover applications

• Front panel display can be inverted for use on cabin wall mounting

• Capable of all site measurement and stakeout operations within radio or cellular coverage

• Easy-to-use menu system for rapid configuration and status checking

• AutoBase technology for rapid and automated repeated daily base station setups

• Can broadcast corrections through multiple radio links from one base station, for example, through an internal 450 MHz radio and an external 900 MHz radio or over the internet

• Rugged, weatherproof construction with an IP67 environmental rating

• –40 °C to +65 °C (–40 °F to +149 °F) operating temperature range

• 10.5 V to 28 V DC input power range, with over-voltage protection on a 26-pin connector

• 11.5 V to 28 V DC input power range with over-voltage protection on a Lemo connector to prevent deep discharge of external batteries

• Capable of rover operation within a VRS network and Internet Base Station service

• Moving baseline and heading capability when the SPS855 receiver is combined with any SPS85x or SPS55xH receiver (ensure that Moving Base/Heading mode is installed on each SPS855 receiver).

• RoHS and WEEE compliant

• 1 pulse-per-second (1PPS) output - standard on Marine version, optional on Construction version

Base station

• Unrestricted operational range for rovers and grade control systems

• Base station and rover operation in a single receiver depending on the options purchased

• Integrated transmit radio or add-on SNM941 Connected Site Gateway

Rover

• 5 Hz, 10 Hz, or 20 Hz measurement update rate (10 Hz maximum in Heading mode)

• Integrated receive radio or add-on SNM941 Connected Site Gateway

• Base station-free rover capability within a VRS network or Internet Base Station Service (IBSS)

• Base station-free rover capability using CenterPoint RTX/OmniSTAR services

• Operates as an SBAS rover when coverage is available
