Trimble - SPS751 and SPS851 Modular RTK GPS Receivers
Trimble® SPS751 and SPS851 Modular RTK GPS Receivers are ideal for semi-permanent or permanent setups, marine-based applications, as well as construction rover applications. The antennas can also be mounted in a marine vessel or on a site supervisor's vehicle.
The Trimble SPS751 and SPS851 receivers combine the radio and GPS receiver in a single housing. This allows contractors to secure the majority of their investment inside a site trailer or carrying case, protected from the elements and/or theft, leaving only the antennas outside.
Available in a range of options to suit your individual applications, flexibility and performance requirements, versatile Trimble GPS receivers are a future-proof investment. The receivers are designed to use all curretly available satellite signals including L1, L2 and the GPS modernized L2C code. The SPS851 receiver can be upgraded with GLONASS and L5 GPS signals to optimize performance in areas of tough GPS-only conditions and maximize your investment well into the future.
The Trimble SPS751 offers the following key features and benefits:
1cm horizontal and 2cm vertical accuracy in RTK mode – providing maximum RTK precision available today
Tracks L1, L2 and L2C GPS signals
Uses the industry-leading Trimble RTK Engine for real-time corrections
1 Pulse Per Second (1PPS) output for precise synchronization with other positioning equipment such as marine multibeam echosounders
Operational in all Location GPS modes, including Satellite Based Augmentation Systems (SBAS), DGPS, OmniSTAR (VBS, XP, and HP services, subscription required), as well as high accuracy precision RTK mode
Can be used with an external radio modem, or optional built in internal radio modem for transmit / receive of CMR or RTCM corrections
Modular design allows mounting flexibility for greater accuracy and added security
Add on the Trimble SPS551H GPS Receiver for precise heading output
Supports Base Station, Rover and Moving Base for marine site applications
The Trimble SPS851 offers the same features as the SPS751 plus:
Upgradeable to track GLONASS signals for increased performance in areas of obstructed sky view for GPS-only
