SPS651 Modular GPS Receivers
Trimble SPS651 Modular GPS Receiver
The Trimble® SPS651 Modular GPS Receiver is the receiver of choice for a Site Supervisor's System - where cost-effective real-time positioning with precise vertical measurement is required. With 10cm (location) horizontal accuracy and 2cm (precise) vertical accuracy, contractors can be confident knowing they are getting the right positioning tool at the right price.
The SPS651 receiver can operate in all Location GPS modes, including Satellite Based Augmentation Systems (SBAS), DGPS, OmniSTAR (VBS, XP, and HP services), and Location RTK mode.
It can also be upgraded to track the GLONASS satellite constellation signals - allowing it to operate in areas with obstructed sky visibility or during times of limited GPS availability.
Modularity allows the flexibility to mount the receiver and GPS antenna in a variety of ways, example on a pole, backpack, site vehicle, light machinery or marine vessel. The receiver can be mounted in an accessible location where it is easy to configure and is secure from theft and weather, while the antenna can be mounted in a location that provides clear line of sight to sky and that reduces the potential for multipath.
SPS651 Features and Benefits
- 2cm (V) and 10cm (H) accuracy in Location RTK mode - provides the RTK vertical precision at a reduced cost
- Tracks L1 and L2 GPS signals, upgradeable to track L2C and GLONASS 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
- Can be used with an external radio modem, an internal 900 MHz radio for CMR corrections or an internal 450 MHz radio for transmit/receive of RTCM corrections
Applications
- Construction site supervisor operations
- Pole and ATV-mounted rover applications
- Dredging operations,Harbor construction or Land reclamation
